Industrial Resin / Projector Modification
Hope you are enjoying the weekend! We tested industrial resin from Fun To Do (which turned out to be very strong) for dental applications. This resin could be used for vulcanizing.
This dental model is from Vidal (www.thingiverse.com/thiing:123245). It was printed with XY resolution of 45.5 microns and Z layer thickness of 50 microns. The exposure time was 2.5 seconds, and the dimensions are 64 mm x 49 mm x 12.8 mm. It took 2,675 seconds to print.
This model below is for clear aligner application and is provided by Juitang Cho. The size is 80 mm x 57 mm x 26 mm. Resolution is XY: 53 and Z: 50. Exposure time was 4 seconds, and the printing time was 6,302 seconds. We used Fun To Do's industrial resin for this as well.
There are three screws that secure the lens system to the projector body.
We used two 0.8 mm spacers for each screw.
The gap is sealed with black tape now. The solution to have no gap at all is to customize a big 1.6 mm thick ring spacer with three holes for the screws. We will definitely consider this if the demand is there. We will include a question in the survey we send to our backers.
