Simple robot pendent by gwygonik Jun 9, 2013

Description

This is a small robot pendent I modeled in Blender for the sole purpose of printing something simple, tiny, and intricate with my Formlabs Form 1 3D printer. I printed at 50% the size of the STL as a starting point; that is the print shown in the pics.

FYI - I posted a set of updated pics of the pendent at 0.025mm layer height. You can find them at the blog post linked in the description. These might help your decision ;-)

Also, your reminder that the gray might take a longer exposure helped me get a 0.025mm print that worked -- there seems to be an adhesion problem with the first few layers with the stock settings. I used the gray settings -- a slightly longer exposure -- and it worked perfectly.
The initial resin is clear. Crystal clear. However, once you start sanding off the support bumps, things start to get "frosted". If you go look at my Zookins thing here on Thingiverse, I posted an "I made this" pic of the elephant that had been sanded with a 400 grit sandpaper. I re-sanded last evening with a 1500 and it is super smooth and only slightly frosted. The edges are still clear where I didn't sand, but the flat sides are not.

I'd suggest looking at the Formlabs support site (http://support.formlabs.com) to see more pics from beta folks and the discussions going on there. You might have to dig a little for pics.

Perhaps of interest to you is that one user tried their b9 resin in their Form 1 and it worked. In theory, if you can burn out the b9 resin, and you can use the b9 resin in a Form 1, you could go with the sexier machine, and/or the Formlabs resin may also have similar burn out properties.
Frankly I had been looking at the chat/blogs and so far
i had been hearing no deliveries on the form. So I am glad to see it has in fact been delivered. (a HUGE concern if looking to buy).
I had read 3 things which have made me lean towards the b9
1) the resin has in fact been burned out for castings. (my main intrest)
2) the open source of it.
3) reports seem to indicate a finer resolution on the b9.

now as to the form, size, simplicity and it is a sexier machine.
Your prints are the first ones not from the forms folks I have seen, Which is a very good thing as vaporware abounds in the 3d machine world.

one question, I see your resin looks clear. I was under the impression it used a coloring agent to limit the UV penetration.
is the resin in fact clear?

Thanks for posting this, I have been very interested in seing formlab output.
I am currently trying to decide on which photopolymer printer to purchase.
I have been considering the b9 and the formlabs units and so far have not seen formlab output.
so thanks for showing some output.
my end-goal is lost wax casting .
I have to say - the thing I love most about the Form 1 is that I haven't had to do anything except plug it in and press "print" (well, "Form" is the button in their software). There really are no settings to adjust apart from support generation and layer thickness, and there are zero mechanical adjustments you can make. It. Just. Worked.

My first print was 5.5 hours long and I let it go and it was awesome when it was done. I honestly would never do that with my Thing-o-Matic because I know there are too many variables that I, as a user, can mess up - both software and hardware - and often do. That was my concern with the b9, especially as a kit. I like focusing on the object, not the process of printing it.

As for lost wax casting, I don't have the equipment to even begin to test if this will burn out, and there hasn't been any reports from the wild. If only I knew someone who did... ;-)
