3D Printing - "It's all about design and quality output. Not how fast the printer can run."

DSCN0086I used my DLP printer to create a castable resin master model, of an amateur radio finger ring. The client asked for it to look like a mobile HF amateur radio transceiver.

I wasn't sure if I should publish this here or in my KautzCraft jewelry blog. It's here because this part of the project is pure 3D printing. The casting I'll publish elsewhere.

I am not exactly thrilled with how these two prints "developed". The details are very small so I was concerned. I have the exposure too short as there seems to be what I call "blooming" in the tiny details. Under exposure creates "rubbery" layers that pull up and form fat blobby areas. I am going to tweak the tine settings and do another run. Unfortunately a "run" takes 6-7 hours.

I think I may have set the slicing at 50um on this run instead of 35um as I intended. This next run is definately 35um. I am still in the experimental mode until I get all the timings nailed.

The last two pictures is where I found the proper "nails". I laid the ring flatter on the plate which reduced the number of layers and the print time. I found the correct (longer) exposure values for the castable resin. A very light sanding touch will remove the layers in the last picture which are almost invisiable to the eye.

 The stopping point on the printer. Let there be pink (parts).  Decent printing. The plate removes easily.

 Separation from the plate is not difficult either.  Some slight differences between them.

 Left ring has better details. Not perfect.  Intro the UV cure box for a good long soak.

This is the quality I expected. The callsign is very crisp and correct size.
