Hello,
I've lurked around here a few days for 3d printer recommendations and ended up buying Phrozen Sonic Mini 4K. There aren't many digital cases for us to buy expensive 3d printers exclusively made for dental labs. I noticed the great reviews of this printer from some of you and decided to try our luck with Phrozen SM4K. I am thinking of it as a stepping stone to get more experience in 3d printing and actually try them on some of our digital cases. But I'm having a bit of an issue with the printed models.
I've been trying to print full arch models. I noticed that the side of the model came out like the side of a book. It looks like a bunch of flaps that ended up not being bonded when it's printed. I've researched the internet and was told to increase the exposure time, so I increased the exposure time to 4s and bottom exposure time to 40s. I've also replaced the resin and readjusted the z-axis. This tends to happen on the side where there's a fair amount of flat surface. When there are details, it seems to come out fine. I use Aqua Resing Gray 4K (Phrozen's standard resin). I didn't angle it because I was only printing one at a time and wanted to print one quickly. Angling it required like 5 hours of printing.
Is there anyone who had a similar problem? Are there standard parameters people use? What kind of resins do you use? I would really appreciate any help. Thank you.
