| Apr 18, 2019 at 16:20 | comment | added | Joseph Crozier | Update: Contacted shapeways and studiofathom, also had an extended conversation with formlabs. Shapeways and studiofathom were both very polite but passed on the project, studiofathom said "we reviewed the conversation and those requirements will not be possible on our equipment" and shapeways response (via phone) was similar. Maybe its a weird scale in between microfluidics/nano and normal printing Form however changed their tune (compared to what previous sales rep) told me. Their solutions specialist on the phone seems to think the holes I need could be down to about ~50 microns | |

I bet that has to do with the fact you have elongation of the dot from the mirrors angle. Do note that post processing (drilling it out) might save you some $$$. I would make a cast of the thing you showed with no holes hit it with a CNC or some sort of precision drill. | |
| Apr 17, 2019 at 20:35 | comment | added | Joseph Crozier | I've spoken with representatives at Form about the form 3, and apparently the 85 micron laser doesn't equate to 85 micron thickness walls. Their best guess was 125-150, which to be honest isn't much better than the 200 we currently have with the j750. An expensive printer wouldn't be an impossiblity (again, we have a quarter million dollar j750 at the moment) but yes, it'd be nice if I didn't have to go out and find funding for a giant printer for these tiny tubes. Do you know of any websites/service bureaus that can print in this detail as a service? | |
