3D Printing Process with Sprintray Pro 95 Printer

This video reviews the practical process of taking a sliced spr. file and converting it to a physical printed dental model.
The full process includes: File Upload, Printing, Washing and Curing.
A video outlining the prior step in conversion of a 3D scan with an stl. output to a processed spreadsheet file can be found on my channel here: • Digital Dental Model P...

Thank you for this video ,This was very really detailed and helpful
Would it be possible to make another video on how to make a ceramic crown or other crowns that could be done
Looking forward for more videos

@@mohammedzzzz610 thanks, I specialize in orthodontics and don’t have any useful info on general or restorative dentistry methods.

David, did you ever experience printing issues such as no models were printed/ not curing per layer? If so how did you find the solution to your problem and did it have anything to do with your projector?

[@davidjensen4957]

That’s a good question. There are a few possibilities (from most likely to least likely):
1. On your digital design, the models have not been completely set on the print plate.
2. Your first few layers may not have had enough cure time to thoroughly stick to the print plate.
3. Your print plate may not have sufficient texture to allow the resin to adhere during the first few layers.
4. You may have printed with resin that has started to separate phases. If you stir the resin in the vat and you can see swirls, it needs to be mixed more.
5. You may have cured material on your FEP plastic layer.
6. Your resin may be old and possible less reactive to your light source.
7. Your reflector plate may be dirty if it’s a projector.
8. Your projector may not be powerful enough, or is getting old.
This would be the sequence I would follow. Hope it helps.
