Just wanted to give something back to the Form2 community =)
I am a jewelry designer who recently got into the business and now is experimenting with the Form 2 in printing my own designs and casting them with a professional casting house.
I am also a micro pave diamond setter, so many of my designs are aimed at putting very small diamonds in the surface at a later stage.
Bought a printer this March and started prototyping using the Clear resin.
We then loaded a cartridge of Castable and just send our first batch of 8 models to a casting house to be casted in silver before moving onto gold.
Below you see my layout for the this print.
I struggled a lot with the placement of the support beams.
Somehow the program almost always wants to position my rings upside down.
This is not how I hoped to be printing when I bought the printer.
So several times I ‘force’ the rings in an upright position or at a small angle.
All at 0.0025 for the highest detail.
Below you see a small failure in the top bezels of this ring. I know it is a very small and detailed ring but it is designed for micro pave setting of 1.5mm diamonds. I will work this out by repairing this using a laser welder when the model is casted.
This image is more zoomed in and shows that the printer was unable to create the bottoms of the top bezels. This was probably due to the fact that I did not place supports there.
Does anyone of you guys have a better suggestion to print this ring? At a different angle? More or less supports?
Below you see a picture of a signet ring that I made supports for in my 3D design program (Gemvision Matrix). It positions the ring upright on the printing platform and I create a very small base. Thereby making it a little bit more difficult to remove it from the platform but saving huge on printing liquid. Looking at the print you can see that this also worked fine.
At this moment all the models displayed and some extra are at a casting house.
I’ve cured some models 8 hours and others 2.5hours. So I can determine the differences in the results. Wish me luck =)
My learnings so far are:
- Make sure you place the model at the best angle but do not let the software trick you
- For ‘over-hanging’ parts always insert a support.
- Sometimes an easy support in the middle does the trick
My wishes are:
- Make it possible to vary with layer thickens
- Communicate openly about other resins that are castable and that you guys suggest
- Provide a best practice in placing supports for jewelry printing
- Make the resin re-usable. So that the supports and the base platform can be ‘melted’ again and re-used for further printing.
