Selective Laser Sintering: Alpha 1 by peter_ Jun 22, 2010

Featured Thing!


This is the design for a /really/ inexpensive dual z-axis table mechanism for an open source selective laser sintering 3D printer that I've been designing. This is a follow up to the selective laser sintering powder test rig that I recently posted ( thingiverse.com/thing:3389 ).

Is this project dead? :'(

So this is great...did it print something?

(the left side is designed to be cut with 4.5mm material, while the right side can be cut with 3mm material, though you may choose 4.5mm for some things, such as the gears).

I have finished the SolidWorks Model and have also uploaded rendered short video to Youtube for those who wish to view it address is - http://youtu.be/rukVdHIjH24

I have the Solidworks 2011 file zipped up but don't know how to upload it here.

Working on creating this in Solidworks just from using posted images and using the layout as a guide. Looks good so far and everything is mating up well so far.

I imported the dxf file nicely into solidworks and now I just need to dimension everything down. It imported the top plate as being 238 inches long. That can't be right. LOL

Can you give me an Idea of overall size?

GREAT!! I am importing the dxf file now. Maybe it will help me with dimensions. Just to give me an idea, what is the size of the powder chambers and which motors did you use?

Thanks for the files

wow, that looks great! i've uploaded the illustrator (original) and dxf (export) source files, just incase they're helpful!

great work!

What are the dimensions of the parts? Bolts sizes etc...I want to put this into solidworks and share once file once completed.

Yes I would like to construct this. I am having difficulty importing the svg into SL. I get most of the outlines but not all of the holes. I am attempting to compensate.

6-32's all around (or a metric equivalent -- I think I designed with 4mm bores, but you'll have to check), except for the carriage bolts. I can't remember what those were, but you can find an appropriate carriage bolt by measuring the nut aperture on the large gears.

it'd be neat to see it in solidworks! any plans to construct the design?

Did this project die?

peter_ on May 24, 2011 said:

the hackerspace where i was using the laser cutter packed up everything and moved across town over a few months, and there was also some overlap where i had to finish my phd dissertation and move away for a postdoc -- so i haven't had access to tools to work on it for a while. but, i have (over the last couple of weeks) been building my own laser cutter, and am hopeful that i'll get to play when that's finished. i'm also very happy for others to contribute to the project, and improve or extend upon my designs :)

way cool!

btw... mcmaster.com sells adhesive backed PTFE tape which will really reduce your friction even more.

This is nice! I particularly like the look of the laser cut wooden parts.

thanks! :)

here's a link to the very first test! (it works!)

This is amazing work. I would love to see an item that was printed on it.

Speaking as an SLS tech, what you're doing here is amazing. I'd love to offer any knowledge I can. I posted in your reprap thread, hit me up :)
