Surface Smoothness

[Hedrus]

Not that i think it's needed, but if you have a few tiny bumps on your final part, could one spray a very fine layer of resin onto the finish part and cure it right away under a UV lamp ?

Couldn't you just use a self leveling primer spray paint?

Hugues and Kenzie - you are both correct. Any paint or coating will smooth out the surface but will come at the expense of resolution. The thicker the paint, the more resolution will be lost.

Kenzie - thanks for the offer for the design!

We are going to contact the designer for permission. Would this ring work for you guys? Please let us know.

Thanks everyone!

I was just on GrabCad searching as well. There are also a few 3dm files that I could convert as well. Let me know if the artist has a problem with it and I'll sen you another stl with artist info.

The 25 micron ring looks great. Can you share the amount of pigment that you added to the resin for this resolution (what layer thickness too). Also, approximately how long did you cure the resin?

Thanks

Thanks

The pigment concentration is about 2-3 % and the exposure time is 1 second. Thanks!

Thanks everyone for the help, especially JDK3D for the design! We actually got permission from the designer of the graduation ring (https://grabcad.com/library/graduation-ring).

We will get this printed asap and will update to see your feedback.

JDK3D - if you still don't mind, we would love to send over Kudo3D's logo for you to incorporate in the design. We can print it after the design is ready. Thanks so much and I'll message you through Kickstarter!

Hi jon@kudo3D. I am interested in your printer for jewelry as well. I can email you 2-3 "generic" files to test print. I will try and email you now.
Regards,
Rik

Hi Jon. I tried email you but obviously have the wrong email address. I have been training in CAD for Jewelry design for over 9-years. Used many 3D printers in that time from $65k+ down to $5k. I would be interested in you trying some sample ring designs. They are my own which I use for training purposes, so you are free to test print, photograph and use them how you see fit. If you can advise an email address I will email you a zip file containing 3 x STL's to test print.
Regards, Rikj

Hi Jon,

The print orf the Grad Ring looks great! - Fantastic detail wit the lens mod.
I have emailed you 3 x typical ring STL's. Would be great to see images on 1-2 of them when you guys get a chance.
