how to build a 3d printer

Now that you’ve decided on what kind of printer you want to build. It is important to understand and know what kind of budget you have and what kind of quality machine you are wanting to build. This is usually done with springs inbetween the two with bolts through both boards and a nut on the other end. You can never have enough screws. These printers have a hotend that is moved on both the X and Y-axis at the same time or independently. Once connected, we can connect the coupler to the motors and feed the leadscrews down through the nut on the bed mount. The RepRap movement has done more to democratize 3D printing than anything else. Yes that’s true. I use simple paper clamps to clamp it to the bed on all 4 corners. I have one of these for my next printer build, but have not tested it yet. I personally use flex plates so removing and adding it after every print can have adverse effects on the bed position but so can trying to pry off a stuck print from a stationary bed. You can put them in any orientation you like, but I recommend going from the top. Attach the thermistor to the bottom of the board through the hole in the middle. The next thing to move onto is getting the linear rails in place. You’ll probably need to put the computer on it’s back. If both motors turn in the same direction, the hotend will move along the X-axis. Core XY is like Cartesian but it's mechanics, has some advantages over the traditional cartesian. It will never be fast. I'm currently building one that is 330 (diameter) and 1250mm high. Not pure acetone, but just plain cheap fingernail polish remover. I even picked a special 3D printer to use with this book. How they work is vastly different from the other style printers. Smooth but slightly resistant from the motor. But you don’t have to buy it or any other 3D printer right now. This 3D printer used for demonstration in this course is especially designed for easy assembly and use, and gives you a head start in building your own 3D-printers for now and for the future. They come with or without teeth in M5 sizes. You might get a print to finish in 14 hours instead of 18 but we're still talking hours. This is because you’ll likely be making changes to the Arduino Mega or other board and uploading firmware regularly. It is not easy switching from one to the other. A Duet Wifi will easily cost you upwards of $150 (that does not include the Touch screen LCD and excellent smart effector). ABS on top of that needs an enclosure around the printer for optimum quality. To mount it to the bearing assembly, I just used regular bolts without insulation. E3D v6 hotend x 01 Nos. Mechanically many printers can now go faster. I get a great kick from building 3D printers. One of the last things before connecting power is installing the hot bed. (Have someone help you if you can). What type of frame do you want to have? If you plan on printing with flexible materials, beware that this gets more challenging (not impossible) with bowden extrusion. This instructable however, is going to take a more general look at what to expect when building a 3D printer. This is only possible due to the rigidity of the bed base. Delta printers work with 3 different Z-axis driven … More recently, manual bed leveling has for the most part, been surpassed by automatic bed leveling. If you’re going through the trouble of building your own printer, you should definitely use a heated bed. They are easy to troubleshoot with a general understanding of 3D-printing. NEMA 17 stepper motor x 05 Nos. A small crescent wrench is highly recommended. Speaking of angles; if you're going rely on connecting extrusions directly to each other, consider getting it pre-cut from the vendor. Some places this is unavoidable like in the hotend, There is a mesh tubing wrap that I would recommend getting that works great to wrap around wires. Now we can adjust the Z endstop so that the nozzle almost touches the glass and the endstop clicks. Usually with a heatsink and fan connected. It’s called The Simple. Anycubic … I highly recommend having a heated bed. Here's is my latest Delta implementation (the C3Dt/bd) at work: If you have to look at it from a complexity standpoint I would say the easiest (and most common) to build is the Cartesian Model, the Core XY is a bit more complex and the Delta is probably the hardest. Building it yourself, allows you to get outside the range of standard sizes. They are connected together via a moving rod that spins along with that axis of movement. With everything loaded, we can now try out our first print….. After we figure out what we’re going to do for bed adhesion. Because the effector is controlled by fairly thin arms you generally don't use direct extrusion but a bowden type of extrusion. One of the most remarkable things about building a 3D printer is that you'll amaze yourself (and can take great pride in) at what you are capable of. Once we get that part put in, we can connect the belt. If not, time to troubleshoot. Many have gone before and many will follow and most that did will are part of a huge 3D printing community that in most part is there to help you. Decide on whether you want to go bowden or direct extrusion. It's nice to have a huge printer but, how often are you really printing upwards of 1 meter? The other good thing: It's all free! Recently, there has been an invention that uses a direct drive bowden configuration. How cool is that? If it does, you’ll need to adjust the tension and equalize it. On the hotend assembly, I used 12x – 3x8x4mm(I ordered the wrong ones and just used them anyway). We can now install the hotend(s) into the XY carriage. Survival Whistle. Ramps 1.4 controller board x 01 Nos. The vast majority of 3D printers are powered by an "Universal Regulated Switching Power Supply". It's currently selling on Amazon for under $400. My second large printer, I made my own roller bearings in 2 triangle formations about an inch and a half apart. I've personally never used anything other than Pronterface (Printrun) for all my Marlin printer. The course will uncover the core processes behind 3D printing and reveal one of the most powerful capabilities of the 3D printing revolution—that it’s accessible to anyone, and that companies like Shapeways make the process easier than ever through online 3D printing. For many printer this will suffice but there's more cooling needed for excellent quality. Steel – Can be bought as angle iron and welded, or as threaded rod and secured with nuts, Very inexpensive. This is for those who have CAD experience but not necessarily those with printing experience. If this isn’t working, you’ll need to troubleshoot the problem. This is when we can put Loctite on the leveling nuts to keep them in place. You are paying for the experience and out of it you happen get a working project. Then home the Z-axis. The gantry moves up and down with two leadscrews powered by 2 motors working in parallel. Now’s a good time to route all of the wires to where you will be mounting the main electronics board. Loop it over itself and put a zip tie on it. The most popular materials are plastic filaments like ABS and PLA, but there are more materials to choose from.If you want a tough and flexible material, plastics like ABS or nylon works great especially for functional parts like gears and integral hinges. I have little experience with this but I'll add some links under the resource step. The most current common seems to be the E3D-V6. If you’re going to put the insulation on the bed, now is the time to do it. If it doesn’t move smoothly, then it’s time to troubleshoot. Also make them strong enough to withstand all of the different stresses that you anticipate. Interested in learning more about creating a new type of printer from scratch. It’s a small 3D printer that you can build from an inexpensive kit. Just so we are all on the same page, Fused Filament Fabrication or FFF is a type of 3D printing technology where parts are created through a layer-by-layer deposition of a molten … You can get away with a cold bed and lower temperatures. You’ll need a second fan on the hot end assembly to cool filament as it prints. Can be expensive for hardwood. The newer version is the aluminum version, the MK3. BEWARE!! Lets go over a detailed assembly of a Prusa style printer first. Determine whether it's a Makerbot Davinci or Replicator. Here are some of the tools I have in my constant reach: Caliper: Make sure it's both inches and millimeters. I allows the user to print (almost)anything he/she could imagine! With a direct drive, you should be able to release tension on the tensioner and directly push the filament through. Several 3D-printing apps allow you to build products of your own without having to know CAD. A plain RAMPS 1.4 kit (shield on top of arduino with simply LCD) will cost you less than $40 on amazon.com. Those can be just plain cylinders. … You can give the files to someone to print for your or even order the parts to be printed. Eventually over time, these wear into the rods causing some slop and sticky spots. I have 4 printers running on this board and never had an issues. It prints better than all previous builds, I designed and created. A KFB 3.0 kit (arduino integrated into controller baord) will go for even less at $35 on Amazon.com. It is a complex belt drive system that requires both belts to move in order for any movement to be made. I personally like the Maketbot type switches that have an LED on but any will work. That's exciting stuff! The Z height varies but is typically also around 200mm as well. Make a 3D printer: Human factors, form & ergonomics is an advanced level CAD course for mechanical engineering students and educators wishing to further develop their CAD skills using Autodesk Fusion 360™ CAD/CAM. Auto Bed Leveling itself is really not the right term. Once everything appears to be level, go around and check each corner again. They have most brands covered and if it's a popular brand you'll be able to get parts that fit. … This is especially helpful if you don’t have a printer to begin with. The Delta Smart Effector has a contact sensor (smart PCB, where a piezo is somehow built into the circuit board) that triggers when it hits the bed regardless of material and has no mechanical parts to it (that I'm aware of). Adjusting each nut on the bottom until the paper barely grabs. It has a regular bowden tube that has an extruder assembly on the hotend assembly. With your software open and the printer connected, the first thing to try to do is move the axis to check and see if they are moving correctly. Learn the basics of 3D printing with a MakerBot desktop 3D printer. Not all of it is fun. One repeating question I get at shows is, how much it costs to build a 3D printer. Cost will immediately go up though. Most common is Aluminum because it is heat resistant and very rigid. A construction 3D printer is a machine that can build houses by depositing a material (concrete for example) layer by layer. Move the Leadscrews so the X-axis is in a comfortable position to work on. Once you have all of the ideas of what style of printer you want, the size and shape, etc…, you’ll want to start thinking about how you need to put everything together. With direct extrusion your stepper motor and extruder sit on top of the hot-end. Concrete 3D printing – a.k.a. Just remember, research your investment before purchasing. hi! There seems to be a difference between the two. If you’re going to use a bowden setup, now is a good time to assemble the extruder and mount it to the frame with everything installed including the motor, just not the bowden tube. Adjust the bed height to be as level as you feel it can be, with enough room on each corner to loosen or tighten each one a certain amount. But if you want to render it, then go for making them as detailed as possible. The claim is that this type of motion allows for much more speed and it produces less artifacts (blemishes) on the final print. The small DVD drive stepper motor can print only maximum 4 cm X 4 cm but this big diy 3d printer … Check out our top picks for the best 3D printer blueprints available. It would look like an H. The center part of the H is what moves up and down and the other axis would be the exact same, except sideways. Arduino Mega 2560 x 01 Nos. You can make very fancy lapse photography videos but simply have the ability to look in on your print from the bedroom is a nice feature to have. Secure the belt to the other side of the Y carriage. Depending on how thick the design parts are and how they are connected will determine the length you’ll need. Wood – Easy to shape and manipulate. It works well but the one downside to this approach is that an awful lot of mass is moved around in all directions. They took a lot of design time, and a lot of small bearings. TL;DR; Bought multiple cheap Ramps boards that ended up costing what the original was. This is also a moral dilemma of quality over quantity. Most popular printers like the Prusa line of printer, Enders and Crealities all operate in this fashion. I think preference will grow based on which you use the first and/or the most. The most common type of bearings used in 3D printers are 608ZZ. Then there are is the BLTouch that does it's sensing in its own way (instructable here). Explore the key technologies that work together to make MakerBot 3D Printers possible. It is simple and sturdy and resists heat as well. If you’ve done the calculations correctly and put the correct steps per mm into the firmware, everything should roughly print correctly. There's something about bending a flexplate and listen to the print separating itself from the build surface. It's a bit more pricey and the heating of your bed might need some adjustments. In order to operate a 3D printer you will need at least the following types of software: Firmware will most likely be Marlin Firmware or RepRap Firmware if your dealing with a 32 bit controller board. Stepper motors come in different sizes and different power needs. If you’re going to use a bowden setup, now is a good time to assemble the extruder and mount it to the frame with everything installed including the motor, just not the bowden tube. Instead go with metal corner bracket and corner plates when possible. That flex would end up with horribly misshapen prints. I also went with them again for my large printer build. First connect one end of the belt onto the Y carriage. Maximize your production capability with the Continuous Build 3D printer. Yes, it can be more expensive (I won't pass judgement on the quality of the cheaper, ready made products) but think of the process of building a printer as a learning experience. Did you make this project? However, the term DIY 3D printer, in its current commonly accepted use, actually means: the first and the last 3D printer someone ever built, which often ends in … At least look into a parts cooling fan that will cool the filament as it is deposited. The second type of printer is notably known as the Ultimaker or Darwin. What kind of power supply do you want to use? Hotends usually heat up very well. Keeps sharpies and pencils around for marking stuff. Lead Screws can be used in place of belts, but the performance is generally not as fast as a belt driven system. Typically, the Z-axis consists of only one leadscrew and two linear rails fixed at one end. You can also "enforce" proper angles by relying on corner brackets and plates. The more common ones are the inductive proximity sensors that will detect metal and in this case an aluminum bed (or spring steel removable bed). This is usually done with springs in between the two with bolts through both boards and a nut on the other end. Of course you could buy a cheap pre made one for $200, but the print area is pretty small, and the quality isn’t the best. If all of those are working, we can now go on to test the function of hotend and the heated bed. (I’ll explain why later on). I even ordered a high power mosfet that worked for a little while, but eventually fried the board traces because it couldn’t handle the power. It’s more logical to go with a size that is standardized rather than unusual sizes. You bed is not adjusted as part of the process. Depending on the size of your printer, most meter size lengths will be more than enough. As matter of fact, when you see an instructable stating "build a 3D printer for less than $200" take into account you may need to buy some tools you don't have yet. Load the filament after the hotend is at temp. If you buy Kit like mentioned above they'll come with generic A4988 or DRV8825 stepper drivers that will do just fine, or you can get something like the TMC2130 stepper drivers that offer features like stallgaurd and stealchop (you won't know, your printer is working unless you look at it). Thanks for checking this out. When it moves down, it moves away. A fair warning: Building a 3D printer is like getting a Tattoo; it will never end with one. If two move up, the hotend moves towards the center between the two rails, and the opposite when moving down. For larger pieces that are structural, I recommend using at least M5 size bolts. The 3D printer shown above is the Robo 3D R1+, it is what we use and one of the best currently on the market. Following are links to useful places to visit to find information and/or answers: https://reprap.org/wiki/RepRap everything 3D printer, Join the 3D Printing group on facebook there's about 70,000 3D printing enthusiasts ready to help, For parts a good place to start would be Amazon.com, if you're patient and can wait a few weeks consider Aliexpress.com, For excellent aluminum extrusion, check out 8020 Inc, Ebay has a bunch of stuff so don't dismiss them (8020 has a discount store there as well), For a lot of the fasteners, plastics and metal pieces, check out McMaster-Car, Following are some of the 3D printing vendors I have done business with, Filastruder.com (home of Duet Wifi and much more), Matterhackers.com good for all things 3D printing. Movement has to be smooth, cheap bearing are not. We can now install the hotend into the X-axis carriage. The 3D printer will print base on the specific design file it was given before depositing layers upon layer of … These should have pulleys on both ends between the frames, as well as another pulley for each motor. And they have gone down in price. Make sure it is fully assembled and is ready to be put in. One rated for more power will not get as hot. Most printers use stepper motors that are called NEMA 17 motors. These will have to be the 4 wire variant. These are all rolling on 12mm rods that are 600mm long. You can hot glue or locktite the bolts to the hot bed on top. It’s best to buy in bulk. These style of printers have a floating X-axis(gantry) that raises and lowers on the Z-axis while the print head (hot-end) moves back and forth on the X-axis. (At least in theory or we screw something up – it happens). But I highly recommend using an allen wrench style bit head. You can move one side by hand if needed to get it level. screw driver set: I prefer to use hex socket screws for most my builds. They are quite a bit more expensive than regular bearings however. Next, we install the linear rails for the Z-axis through the X-axis assembly and secure them into the frame. Start out with the two central rods and connect them to the XY carriage. It will be harder to work with multi-materials when using direct extrusion. Along with those are LM8UU linear bearings. A good rule of thumb is to allow for at least the thickness of the bolt underneath the head and from the wall edge to the edge of the part. The course will cover: Part 1: Intro to 3D Modeling and 3D Printing Your parts would be 3D printed layer by layer, the process repeats.You should assure material extrusion runs smoothly and that it produces thin layers. How cool is that? Simple 12V only output (3 Sets typically), slim design. After a year, the rods have grooves from the bearings digging in to them. But no worries if your not sure yet, there are flex plate systems out there that can be applied to existing beds. It’s commonly available in meter size lengths. You're not alone. Get the linear rails put together and in place on the frame. Why build a frame printer when you can use your ceiling? It's should really be called Auto Bed Compensation. It … These tend to either have plexiglass, tempered glass, or an aluminum plate. If you buy something through one of those links, you won’t pay a penny more, but we’ll get a small commission. If it’s binding, you’ll need to adjust something, or tighten the frame to makes sure everything is moving in parallel. My first board was a Ramps 1.4 board with an Arduino Mega as the brains. The nice thing about it is, you can do it each print if you want (I do). You can also attach another 3 to the max points, but is not necessary. If you haven’t yet, now is a good time to mount the bed mount. Concrete 3D printing – a.k.a. Any difficulty for making a 3D printer feel free to comment down below. If you’ve designed the printer well, there should be a way to tension the belt that will not allow for any springiness. Once you get that done, you can then mount the bed to the bed mount. What type of tools do you have? The Y-axis endstop should be installed on the back of the printer, and the Z-axis endstop should be installed anywhere on the frame or mounts where the endstop will be activated when the bed is up the highest right before the bed will touch the nozzles with the glass on it. Delta printers are unique and rather complicated but yet gracefully simple at the same time. These are highly rated printers as they have very good print quality. By far the most common size is a 200 x 200mm print area. Consider the two most common FFF / FDM design types to choose from: Delta; Cartesian; Delta printers. Besides a 3D printer you will need some non-printed parts like the motors to power it, the batteries, some electronics, the sensors, the remote control unit and some basic skills to put everything together. I personally prefer Bowden designs because they are easier to use regarding extruder design and you never have to put much pressure on the hotend assembly. First try the Y-axis and see if it will home to the 0 location and stop with the endstop. Glass has less of a chance of permanently warping and is far more resistant to wear. I later upgraded this to plexiglass that I got out of an old used LCD Monitor. Duet comes with it's own web interface. There are going to be parts that aren’t as strong as you anticipated. Here is where choices get somewhat difficult. I would suggest going with the Y-axis as the first part to put together. First thing we need to do is wire up the hot bed with appropriate wires. If you're just starting out with your printer build consider making the flex plate system part of your bed (by possibly already embedding magnets in the bottom of your metal bed). Once we have these all together, we should have a bed the moves freely back and forth with barely any friction, an X-axis that moves back and forth freely as well without any friction, and the Z-axis should move up and down without any binding. They work surprisingly well and are very quiet. I'm sure there's more, but these are all the "goto" tools for me that are all in my direct vicinity. All of them come with either two or three wires and all go onto the same spot on your controller board. Usually you’ll want to start off with PLA for a first time set up as it’s the easiest. The bed is stationary and is on the bottom of the printer. If you want to dive right in, I have 3 instructables for three different 3D printers ready to build. I had problems with the heat bed mosfet overheating and cutting out repeatedly. Whichever design you go with, you’ll want to get the basic shape made. You can hot glue or locktite the bolts to the hot bed on top. So you want to build an FFF / FDM 3D printer from scratch? With these two axis alone, you can only print a flat wall. This list of firmware is quite expansive however (see full list here). It’s a small 3D printer that you can build from an inexpensive kit. The follow up question is, why you would pay that kind of money for parts, if you can buy a 3D Printer for less than that. 3D printers use software from two major sources: the printer itself and the computer you use to create 3D printer files. I would shy away from 3D printing corner brackets. The main tool will be a multi-bit set of small allen wrench pieces. Simple 12v only output (3 Sets typically), No on/off switch (can be installed inline with the AC signal – electronics and soldering necessary), Automatic power on power off controllable by printer board, Requires moderate modification (recommend upgrading wire directly off of circuit board – requires electronics knowledge and voids warranty), Weighs down hotend assembly causing more inertia and requiring more power to the axis, Lighter hotend allows faster printing speed, Very common and available (difficult in USA – has to be imported), Can use Standar SAE sizes instead of metric, Complicated bearing assemblies requiring very tight tolerances, Requires additional hardware that adds to cost. Depending on what you are printing, this can get heavy and/or unstable. If using more than one rod, try to get them as level as you can so that they run in parallel and the bed is flat. Using 3D printer plans to build a printer can be a fun challenge. Every printer could be controlled either directly though some software on your PC (something like Pronterface) or web interface in some cases (like the web interface to the DuetWifi. Limitation on movement creates a conical print area which is small relative to printer size. It is the same as far as wiring goes, but it is made of a non-flexible aluminum and seems very rigid. Any difficulty for making a 3D printer feel free to comment down below. Now we can connect the X and Y rail rods. But you don’t have to buy it or any other 3D printer … The Y-axis endstop should be installed on the back of the printer, and the Z-axis endstop should be installed on the bottom of the Z-axis. Has to be enclosed in a cube shaped structure. Now we can turn on the printer, and load filament. Now that you’ve had a look at what the different types of printers there are to choose from, it’s time to decide on which would be best for you. Get the zip tie slightly tight and use two pairs of pliers to pull the belt as tight as you can get it. A set of long needle nose pliers, regular pliers, and angled needle nose pliers. If you don’t have the leadscrews installed yet, now is the time. These style of printers are similar to the Ultimaker / Darwin printers. Filament management is one of those nice to haves but can also effect what and how you print. Eventually the extruder motor failed and I had to replace it. I'll share the links to 3 of the instructables that explain how to build them. I have a 40A Relay and it gets very warm. on Introduction, HelloI am building 3D printer (about 1*1*1m,not for business purposes) and facing some problems. Note: Please don’t get this how to make money 3D printing article confused with ‘theory ideas’ thought up by a generic blog writer trying to piggy-back on the ‘3d printing boom’ and people’s desire to build extra income ‘the easy way’. The answer depends on what you're building but, of all my printers the minimum is about $400. If it is I recommend ordering pre-cut to size from 8020 Inc or openBuilds. infra red thermometer(for measuring hot-end and bed). (Do not tighten the zip tie all the way down yet). Also test the heated bed, something around 60C should be good. If you are such enthusiast (known affectionately within the community as Do-It-Yourself-ers), here’s a guide to the steps you will need to take to make your own 3D printer kit from scratch.Before we get into the nitty-gritty of such an undertaking, let’s talk about the two main ways in which you can personally build your own 3D printer: Remember to try and make every 3D printed part design easily replaceable. Home all of the axis and turn the printer off and let it cool down. Caged frames are great but are only as strong as the corner braces and brackets you apply. This style just works. With it working, we can now connect it to the computer. No matter what type of printer you make, you’re going to have to have something that the bed will mount to. If you have a high budget go a thermal imager so you can check the distribution of heat on your bed (can't afford one of those myself). They don’t have to be detailed down to internal component workings like bearings. Electrical Components Required. After building my large printer (based on this design) I realized that I should have made some of the parts easily replaceable.). Most of my printers run on 1.7A steppers from Amazon.com, although my first build made due with 0.4A. Otherwise, for larger printers, or ones with weaker bed mounts, the linear rail / leadscrew combination would be needed on two opposite sides of the printer. They will still work quite well though. 3D printing is also known as additive manufacturing, or desktop fabrication. The Y-axis motor should be positioned and secured fully with it’s pulley mounted on the shaft. Sometimes you can also print the propellers. Once the parts are printed, use the pictures on the provided web site … Imagine looking down at one axis. Washers are also important to get. Also consider adding some filament sensors to your printer. Print on and have fun! It’s just a smaller version meant to drive a worm gear on a drive gear. Following is a list of features you should consider when starting your 3D printer build project. First we want to mount all of the motors. “Construction 4.0” – is a similar 3D printing technology to the one that FFF 3D printers use. We serve cookies on this site to analyze traffic, remember your preferences, and optimize your experience. Possibly a hacksaw to cut frame parts to length.
