how to build a 3d printer

It would be a good time to mount the main board as well. I have built a Mendel / Prusa style printer and a Darwin / Ultimaker style printer. The bed should move up and down by turning the rod(s). 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. Others like to use build tack, pei, hairspray, pva, gluestick, or blue painters tape. (I’ll explain why later on). We serve cookies on this site to analyze traffic, remember your preferences, and optimize your experience. Temperature applies to more than just the temperature at which plastic melts. If you’ve done the calculations correctly and put the correct steps per mm into the firmware, everything should roughly print correctly. NEMA 17 stepper motor x 05 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. I recommend the 20mm cube for a first print, it’s simple and is a good basic measurement test. My first board was a Ramps 1.4 board with an Arduino Mega as the brains. That said, some of you might actually be more interested in building something tiny. You’ll need a second fan on the hot end assembly to cool filament as it prints. If it prints at all, then all that is left that is needed, is calibration, and the frustratingly fun part of 3D printing. Read on to learn how to build a 3D printer from a kit or from scratch. My first printer build was a Prusa i3 Style that I built for about $220 when the cheapest printer on the market was about $500. 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. The Z-axis is exactly the same as the Ultimaker / Darwin style printers. If you’re going to put the insulation on the bed, now is the time to do it. When my budget allows I'll always try to go with Noctua fans (dead quiet). Movement has to be smooth, cheap bearing are not. Also there are several facebook groups dedicated to desinging/building 3D Printers. Best of luck! Jump ahead to the last segment to get to printing! Now that you’ve decided on what kind of printer you want to build. This may involve some uncomfortable twisting of everything, but it should go together without too much hassle, just don’t break anything! It has a regular bowden tube that has an extruder assembly on the hotend assembly. Feed the belt around either the pulley or the bearing, and loop it around to the other side of the carriage making sure that the belt is not twisted. If it homes correctly, great! sudo ./pycnc will run it in an interactive G-Code shell. … Move the Leadscrews so the X-axis is in a comfortable position to work on. The X and Y-axis are controlled by two motors working in unison to move the hotend forward and back on the Y-axis and left and right on the X-axis. It prints better than all previous builds, I designed and created. I use simple paper clamps to clamp it to the bed on all 4 corners. The extruder is responsible for heating up plastic filaments and is fitted with a nozzle that controls the dimeter of the extruded fiber. This style just works. I use simple paper clamps to clamp it to the bed on all 4 corners. Auto Bed Leveling itself is really not the right term. I haven’t seen any major problems like I’ve seen people post about on Reddit. Usually the belt connected around something round with the belt folded back onto itself with a zip tie to hold it tight against itself. Scalar is pretty experimental and you may find it hard to find the software to handle it. (At least in theory or we screw something up – it happens). 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. After building my large printer (based on this design) I realized that I should have made some of the parts easily replaceable.). Can be expensive for hardwood. Most steppers are 1.8 degree steps but going with 0.9 Degree can get you more accuracy but you'll sacrifice on speed (not always). The Y-axis includes the entire bed and moves back and forth perpendicular to the X-axis. Set the hotend to around 200C. 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. The next thing to move onto is getting the linear rails in place. This is probably one of the parts you don’t want to go cheap on though, as it’s the heart of the machine. You can move one side by hand if needed to get it level. 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. You’ll need to get at least 3 endstops. More calibration and a million Benchy prints… j/k about the Benchies… but it happens…. Before starting any build or design think about what it is you want your printer to be capable of. 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. And almost always having a heated bed, tempered glass is recommended over aluminum. This is also a moral dilemma of quality over quantity. Why build a frame printer when you can use your ceiling? Building a FFF 3D Printer. Also connect the bearings at the opposite ends of the pulleys. After we have good movement all around, we can install the motors and belts. Decide on whether you want to go bowden or direct extrusion. Otherwise, it’s time to level the bed and test a print! If you know you want to build a printer the next step (if you haven't set your mind on any yet) is to determine what type of 3D printer you want to build. There are going to be parts that aren’t as strong as you anticipated. Video/monitoring won't be the first thing on your mind when building a printer but is a nice feature to have. These tend to either have plexiglass, tempered glass, or an aluminum plate. But I would recommend getting a couple 605ZZ or 685ZZbearings for each end. I'm currently building one that is 330 (diameter) and 1250mm high. on Introduction, HelloI am building 3D printer (about 1*1*1m,not for business purposes) and facing some problems. 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. What type of frame do you want to have? Usually you’ll want to start off with PLA for a first time set up as it’s the easiest. This is one of the most important parts of the printer and requires a lot of decision making. The most common printers are either a Cartesian 3D printer or a Delta Kossel 3D printer. You can now connect all of the wires to the mainboard. 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. Instead measurements made of your bed's inaccuracies are applied to the print process and the Z-axis will compensate for them. If you want to dive right in, I have 3 instructables for three different 3D printers ready to build. All things Duet:, PrintRun for operating your Printer from PC:, OctoPrint will allow you to make any Printer wifi (with so much more):, Best places to download designs to print (or designs for printers). This list of firmware is quite expansive however (see full list here). 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. Learn the basics of 3D printing with a MakerBot desktop 3D printer. Once the frame is cut, you need to print out all the parts for the printer. Eventually the extruder motor failed and I had to replace it. Sound will start playing a bigger role over time. Make sure it is fully assembled and is ready to be put in. Oh, did I mention the hang printer? Then there's the different fans around your printer that can get pretty annoying over time. All we involve our 3D printers is offer the filament the right conditions to work its magic. Core XY is like Cartesian but it's mechanics, has some advantages over the traditional cartesian. Several 3D-printing apps allow you to build products of your own without having to know CAD. You should be able to turn the leadscrews together and the X-axis should move up and down smoothly. Make sure it provides enough amperage for your needs. Host software comes in handy when your printer does not have a display or does not have a display yet. The belt should be taught, but not so much that it restricts movement. Once you get it in, you can then install the blower fan for the prints. Get the linear rails put together and in place on the frame. It is important to understand and know what kind of budget you have and what kind of quality machine you are wanting to build. It’s just a smaller version meant to drive a worm gear on a drive gear. Print on and have fun! The 3D printer is commonly utilized to build three-dimensional products from a computer-assisted design model or a digital file, commonly by continuously depositing material layer after layer … A cheap readily available alternative has yet to implemented, but there are other options. It’s called The Simple. 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. Put the printer back into it’s normal orientation and test the movement of the Y-axis. Setting Up: Identify the kind of 3D printer. The bed is stationary and is on the bottom of the printer. Possibly a hacksaw to cut frame parts to length. Also make them strong enough to withstand all of the different stresses that you anticipate. If you want to print at 300mm/s (few can) you'll need higher melting temperatures and generally better nozzles to keep the molten plastic flowing fast enough. We shouldn’t have to adjust the bed level again. It's a bit more pricey and the heating of your bed might need some adjustments. I had problems with the heat bed mosfet overheating and cutting out repeatedly. The most current common seems to be the E3D-V6. It works well but the one downside to this approach is that an awful lot of mass is moved around in all directions. Smooth but slightly resistant from the motor. 3D printing is such a fun way to produce creative work—and it has totally taken off. This is only possible due to the rigidity of the bed base. There are two common types of power supplies available. if you want good bed adhesion and which can add magnetic beds to any printer with the and the Flex Plate System (I'm a huge fan). 3D printing is also known as additive manufacturing, or desktop fabrication. Keeps sharpies and pencils around for marking stuff. Secure the belt to the other side of the rod bearing assembly. It’s more logical to go with a size that is standardized rather than unusual sizes. 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. 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. The X-axis moving a possibly heavy extruder stepper motor from left to right and the Y-axis is moving an entire bed and with that, the entire model you're printing. You will get a zip folder. You can hot glue or locktite the bolts to the hot bed on top. Before we put them on the printer, make sure that you have the appropriate bearings/bushings in place on each rod if you’re using those. For the X-axis, we can assemble everything that goes on it except for the hotend and motor. Build it virtually. Places to look for aluminum extrusions would be and 3D printers use software from two major sources: the printer itself and the computer you use to create 3D printer files. Now is a great time to tighten the nozzle and make sure everything is tight as can be without breaking it. Caged frames are great but are only as strong as the corner braces and brackets you apply. 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. Allen wrench Hex Key set (mostly for some of the bigger stuff like M6 Hex nuts), Smaller ruler (metric) for the places calipers can't reach, tweezers as there's a lot of small stuff happening, I like to use a metal deburring tool (also useful for post processing 3D prints), lighter or small torch for crimping tubes. A couple of different tools will be needed. The Ramps board doesn’t seem to handle the amperage very well and will get very hot and overheat the poly fuse, the mosfet on board, burn up the input power lead or blow a trace on the board itself. The Z-axis may be difficult if you have the leadscrews in, which will be covered in a little bit. Without connecting the printer to a computer yet. I mentioned Stall guard earlier which theoretically allows you skip end stops altogether (when the axis goes boom at each end of the rail it will stop) but my experience is that, that feature is not quite there yet. Following are links to useful places to visit to find information and/or answers: 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, if you're patient and can wait a few weeks consider, 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, (home of Duet Wifi and much more), good for all things 3D printing. Generally popular Diy 3d printer using arduino mega is using old DVD drive,s stepper motors but this one is big 3d printer. Much of the magic in FDM 3D printing remains in the filament. Read on to learn how to build a 3D printer from a kit or from scratch. If two move up, the hotend moves towards the center between the two rails, and the opposite when moving down. The very first printer I built was made entirely out of acrylic, All printers after, used aluminum extrusion for various different types of frames (cage CoreXY, Cantilever, Delta). The X and Y-axis both use GT2 belts while the Z-axis typically use 8mm leadscrews. What you can make with a 3D printers will depend on the 3D printer quality, the design of the object, filament material used and skill of the craftsmen. There is an arm attached to each one of the belts that slides along the linear rail. Both of the X and Y-axis have a linear rail that they move along. That said, you can 3D print the frame and the housing structures. So I recommend getting authentic brains for your 3D printer at the bear minimum of genuine parts. Proximity sensors are nice to have as they enable you to use a feature called Auto Bed Leveling which ironically doesn't level your bed at all. Be ready to press the emergency stop in software or disconnect power if something happens. They are all still going strong and working great (still need to upgrade the Z motors). You can put them in any orientation you like, but I recommend going from the top. On the opposite side of the belts, there are bearings that allow free movement of the belts. I get some of my aluminum extrusions used on but be aware of scratches and non-uniform/exact angles. Affixed to 3 sides of the printers are the linear rail and belt mechanisms. Boards and mosfets Hi would it be possible to get a visual of each part and of the finished printers? There are 2 belts each for both the X and Y-axis. The endstop for the Z-axis should be easily adjustable with a screw of some sort. These printers are usually in a cylindrical shape with three or six faces. If both motors turn in the same direction, the hotend will move along the X-axis. There's cons and pros to both. It originated as the Mendel, then the Prusa Mendel, and is now in the form of the Prusa i3. If you’re going to put the insulation on the bed, now is the time to do it. Attach the thermistor to the bottom of the board through the hole in the middle. Ask for help when you need it. Washers are also important to get. After the frame is together, the first thing we want to do is assemble the X and Y-axis assembly. These are highly rated printers as they have very good print quality. It should move smoothly, but have resistance from the motor turning. At least look into a parts cooling fan that will cool the filament as it is deposited. By far the most common size is a 200 x 200mm print area. I'd like to say is all you need is a screw driver and a hack saw but in general you'll find you need more tools than that. step angle good 200 steps/revolution) that range from 0.4A to 2.0A. The video below illustrates what happens with you swing back and forth 6 skinny sloping towers at 200mm height. With it, I can heat up to 110C in a little over 1 minute (Where it would take over 10 minutes with a low-end MK2-bed heater). So I went with a larger NEMA 17. Well here is a good place to start. Any difficulty for making a 3D printer feel free to comment down below. These are just microswitches like in a mouse button, but with a lever action. 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. I'm sure there's more, but these are all the "goto" tools for me that are all in my direct vicinity. Consider the two most common FFF / FDM design types to choose from: Delta; Cartesian; Delta printers. Considerations, like 24 Volt, Nema 23 instead of 17, linear rails and 32 bit boards can get you there but don't forget about the plastic you need to melt.
