I am working on a project where we need an array of small needles, about 1.2mm tall, 0.5mm diameter. I have verified that the printer can decently print this feature:
(Yes it is different resin, I had the same issue with Black resin)
I verified that my STL model is using high resolution. I can’t figure out why the needles aren’t printing as part of this mold.
Here is a previous version of the mold, where the needles are shorter (0.7mm) and there are walls on the print (which I was worried about creating “cups” with):
You have a rim around the area with the pins. This may cause some cupping effects. It may be better to print the pins separately as inserts into the main body of the print.
I actually just access to this printer. The lab owner purchased it refurbished about a year ago, and I doubt the optics have been cleaned. Is that something that would become an issue within the span of a year?
Thanks for the advice, I was considering this but didn’t want to do it because of laziness. I think I’ll give it a shot though, as I’ve wasted too much resin with dud prints.
