Perfect 3D / My School Project I’m currently studying the third year of Swedish gymnasium (high school) and got an assignment to create a product or write an essay, as a person who loves to build stuff I choose the first alternative. Since I got my first CAD program 6 years ago I’ve been hooked, I used it for everything, school as well as hobbies. Something about having a complete model in 3Dimensions has fascinated me. The problem came when you wanted to have something in your hands from the model on the computer. I knew about 3dprinters but I also knew you had to be really rich or a computer scientist to get your hands on one. In the end of 2013 I built my own CNC to machine longboards (I was 17 at the time). It was a crude machine, all MDF and 3 Nema 34 motors powering all the axis. It works for what it is made to do but was more of a stepping stone. The CNC got me thinking, why couldn’t I if so many other people already have, build a 3D printer. I had no prior experience with 3d printers except seeing a Ultimaker 2 in real life (once) and watching the most basic Youtube videos about them. So when I got the assignment from school I decided it was time to build one. As I usual I skipped the whole process of gathering information of how to do it correctly and CAD’ed the whole printer with my limited experience. This is the result. nrRnasU.png mod_embed_images_loadimage('81f54445f9205fa0cf2353103f015064', '/forum/thumbcache/cda/ed3/9b1/433/599/5d1/05f/909/e99/2f9/f9_800x400.png', 'http://i.imgur.com/nrRnasU.png', 'https://reprap.org/forum/addon.php?1,module=embed_images,check_scaling=1,url=http%3A%2F%2Fi.imgur.com%2FnrRnasU.png', '', 496466, 800, 400, 'Loading image ...', false); The problem was to get together all the pieces for the printer.

They were really helpful and sent me the parts almost instantaneous. The second company to answer was Feed the Printer, a distributer of 3D filaments and tools to assist in 3D printing. I would really recommend buying from them since they have great service, quick shipping, low prices and sell good quality products. (Im going to buy new material from them as quickly as I get the money for it). The stuff I couldn’t get my hands on trough sponsors I had to buy via ebay. Construction of the printer went quite smoothly when I had gotten all the parts. Some I had to make myself, some I got printed trough www.3DHubs.com.

What size extrusion did you use?]]> gmh39 General Tue, 14 Apr 2015 21:06:46 -0400 https://reprap.org/forum/read.php?1,496466,496887#msg-496887 Re: Perfect 3D / My School Project https://reprap.org/forum/read.php?1,496466,496887#msg-496887
The actual design is my own. I will say that it was inspired by the Ultimaker in the sense that the rods work both as rods for the linear movement and shafts for the rotational movement, but except for that everything is my own.

I started the build by cutting the rods.


Then i machined the pieces i needed to make myself.


I collected all the pieces.


And then assembly started one piece at the time.




Then the X/Y assembly.

The hot end and the Z-axis.


Close-up of the z-axis assembly. Note that the bottom plate was supposed to be acrylic but i ordered the wrong size so now its painted plywood.


The printer from above.




So to the print quality all the prints use the same speed 50mm/s perimeters, 100mm/s for infill, 200mm/s for travel moves.

First the "standard" Owl 0.2mm resolution, PLA.


And a Treefrog 0.2mm resolution, PLA.



Then to my own little random abstract shape. 0.4mm resolution, PLA


0.2mm resolution, PLA


0.1mm resolution, PLA


And then the odd one out 0.05mm resolution. Notice how the same percentage infill became much less (bug in slic3r??) also the retract stooped working. As you see the print skipped in Y-axis, it has never done this before and never since.



Tell me if you want a overhang test or a bridge test.

The doors with a furniture hinge cut in two. The bottom panel with four angles i designed and printed to fit within the t-slot i drilled a hole trough the bottom panel into the corner pieces and threaded a screw into it.
