|First Model - Looking for an Evaluation [message #66835] Thu, 25 April 2013 04:50 UTC
So I just complete work on my first model for printing with Shapeway. I've not done much 3d modeling and never had anything 3d printed before. For some reason I (perhaps foolishly?) picked a tiny piece for my first model.|
The piece is only ~12x6x3mm with details of ~.1mm.
#1. Can I expect any of the sub ~.1mm details to come out in the final print?
#2. Looking at the materials it seems that Frosted Ultra Detail will be the only material suitable for printing this level of detail, but I could be wrong?
#3. If I wanted to do multiple copies of this model in a single print job would it be necessary to add a 'sprue?' Is this even possible?
#4. Are there any other design considerations I may have missed?
#5. Is there a 'best' orientation for my models?
I've attached the exported STL to this post, but I have the original Blender file if that is better for giving feedback.
Anyways I'd appreciate any answer and feedback the community might be able to give. Looking forward to printing my first models with Shapeway!

Thanks so much for your help.|
The errors in the model were troubling to fix, but after struggling with it a bit, I managed to get them correct. As your surmised, the Boolean join did not want to play nicely with me. Thank you also for the recommendation of Netfab. Even when everything looked good in blender it seemed I still got some errors after exporting to STL. Perhaps introduced during the export process? Or maybe I'm just not good enough to catch them in the app.
Two more questions:
#1. I was considering applying some subtle smoothing, but given the tiny scale of this model I wasn't sure it would be worth my time as that level of detail might not show up. Is this assumption correct?
#2. How high up should I emboss my text/symbol for best effect? I went with .5mm though it does seem to stick out a little awkwardly to me. Would a lower height of embossment still give me a good effect? Should it be even higher? The target material for this is Frosted Ultra Detail.
I've uploaded an update copy of the mesh as well.
Again thanks for everyone's time and attention.
