Building from scratch!

Recommended Posts

Hi guys, Halo from Russia

First of all whant to thank Erik for Nice and SMART design and lasercut plans!

... after deep digg in to the 3D printers world I decided to build printer by myself from scratch, I think that Ultimaker has the best Design for today so I'll try to build the Ultimaker

I have already sourced almost all parts needed, some days ago I managed to lasercut frame pars in the local Jedi ofice ;) so building begins

Here are the first results

The vintage TV-set is ready, waiting for the screen ;)

So if it is still interesting for somebody- Let me continue ;)

When I was ordering shafts and bearings from vxb, I did not found Long LM12LUU bearings so decided to order 2x2 short LB12UU 12mm Ball Bushing 12x21x30 Linear Motion Bearings instead!

due to It's lenght 2x30 mm vs 57mm(jriginal) I redraw and recut bearing slots in left and right arms

And finally I've got my Z-stage almost done

So here it is after some vintage paint job :)

As much as I dig deeper Into the Ultimaker design as much I understand and love Erik's engineering Ideas and solutions, the Design is Awesome!!!

Im still unhappy with my X-Y movement with short bushings so I went to a automotive parts store to search for something more convenient

And I found :) I found nice brass Valve Guides from VW or AUDI engine!!! It is 8 ID and again 12 OD, 36mm long :O and quite cheap!!!!

old short bushings are also here on the right upper corner

After some reaming with the spechial reamer(you can see it near bushings on my picture) which I've got in the same store, bushings are now PERFECT!! So I need to find somebody with the real lathe to make them 11mm or finally redesign a wooden parts to use AUDI parts as is :lol:

Guys!!! Need your help!

I'll be more then HAPPY if somebody can measure some head sizes if it is not a secret :)

One more question, how does the head work for you? Is it enough cooling of upper (cool) zone of the head, or it would be better to make additional heat sink or even cooling fan on the upper side of the head???

I was askng somebody to measure a real thing but it seems that tere is a huge secret, but anyway, thank you guys for such a strong supprt, I will make yet another improvisation;)

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
