Re: aluminum casting - 15 years ago
As a warning, Burning out or just burning construction grade foam (or any foam) is highly toxic and dangerous. If you are going to do this then be sure to do it in a safe area with no one around while wearing the proper safety equipment (I.E. Respirator, Goggles and Face shield if needed).by Iceman086 - Casting and Moldmaking Working Group
Re: Big Printer - 15 years ago
I am hoping to keep the extruder light enough to not need more powerful motors on the X Y axis and feed motor. The feed motor will be mounted seperately from the extruder head that will be moving around. The idea being that with a light weight printing head/mount I will be able to get faster prints. The Z axis will need a bit more beef to it so I might consider using a NEMA 23 there. Until I canby Iceman086 - Reprappers
Re: Big Printer - 15 years ago
Just a quick little update with some pictures. I have been trying to model all of the pieces in SolidWorks (for practice and to see what it will look like ahead of time) and here is where I am at. Some things I still have to add in and others I still have yet to design. But after finding some belts that will work for the scale of this printer I am adjusting things a bit though the overall desigby Iceman086 - Reprappers
Re: Big Printer - 15 years ago
Thank you Sebastien. I found a belt that would work for literally 1/3 the price and several other parts! I will toss a list of links up on what I am looking at for parts tomorrow once I have had a better chance at sorting through everything and adjusting my design to use belts instead of rods. Thank you again!by Iceman086 - Reprappers
Re: Big Printer - 15 years ago
Good to know. I did some digging on Amazon for Small Parts Inc. but came up with nothing. I managed to find some Tire Track Teeth belts at McMaster Carr. From what I can figure it will take a belt that is about 640 mm circumference or so to get the right distance. For the life of me I can't seem to be able create a link to the belt that I found. The best that I can do is share a link to the catalby Iceman086 - Reprappers
Re: Big Printer - 15 years ago
@Andrew Diehl How will you be keeping the extruder/bed from rotating freely with only one round rod? I only showed set of rods in the assembly above. There will be 2 sets, just like the rods above that cross one another to form an X. Where the rods cross is where the extruder head will be focused to. One set of rods will be slightly higher than the other so that the rods don't rub or cause otherby Iceman086 - Reprappers
Re: Big Printer - 15 years ago
Thank you to everyone for commenting and helping. I have been designing and researching over the last few days and here is a piece that I have come up with. This piece is made for the X and Y movements. The idea being that 4 of these can be printed off, two threaded and two unthreaded, to be used for the printer head movements. There are 2 parts to this unit. The top of the "T" shape has a hby Iceman086 - Reprappers
Re: what's wrong with easy to use software like SketchUP - 15 years ago
Have you looked at eDrawings? It is a piece of software that is coupled with SolidWorks but can run independantly. It is what I have used in the past to convert SU files to any other kind of files that I needed. I haven't tried it in regards to 3D printing, but I am hoping to soon. eDrawings Website I would suggest downloading and using the Publisher version of the program. Hope this helps!by Iceman086 - 3D Design tools
Re: Big Printer - 15 years ago
@SebastienBailard Wood will be cheaper than box tube, I imagine. I'd suggest t-slot over box tube, but for a 2'x2'x2' box, the cost may add up. My college has a large scrap pile of 1"x1" box tube and some other various sizes that I am allowed to pick through. If I go the steel route I was going to sandblast the steel to clean it, then after its all welded up and cleaned I was debating using BBQ Gby Iceman086 - Reprappers
Big Printer - 15 years ago
Hello All, I am hoping to put together a proposal for a grant to build a plastic printer with a 2'x2'x2' printable area. The goal is to use alot of the same basic principals that alot of people already set up and put out there. Budget $500 or less. Set Up I am hoping to have the printer head move on the XY axis while the build platform moves up and down on the Z. I think that this will help toby Iceman086 - Reprappers
