I literally unpacked the machine, loaded a model from Thingiverse and a couple of hours later I had a pilot curing in the sun! Easy Peasy. Bob That's easy for you to say. I can only just do basic stuff on the little laser engraver. Fortunately my buddy is well up on that stuff and he's just upgraded to a fancy CAD thing that will do brass. Mind you he wasn't expecting it to come in so many pieces. He's had it months now and I'm not sure if he's finished building it yet. He is a busy boy though so Ill wait calmly for my makers stamp.

Looks better than anything I have seen on Thingiverse. made from 2D art, extruded in Photoshop. Bob Quote
Members Retswerb Posted February 13, 2021 Members Report Posted February 13, 2021 Holy cow. The finish on your parts is night and day better than the filament stuff. What’s the downside? That looks great. Quote

What’s the downside? That looks great. That's pretty standard for a resin printer. After printing, you then have to wash off all excess resin, with water, and then cure in the sun for a few minutes or under a UV lamp. One trick I discovered on You Tube is to place the model in a jar of water for curing. The lack of O2 enhances the cure of the outer layer, making it harder, and produces an even smoother finish. As I mentioned, this is an absolute no brainer, plug and play as described. No assembly, no fiddley parts, just pour some resin in the vat, load your model on the provided thumb drive and push print. Time to print is based solely on height as it prints .05mm every 2 seconds So a 6" rod will take the same time as a plate full of 6" high models. So the trick is to angle tall objects so the will print faster and better. The down side is that currently there is less choice in water washable resins than in filaments but there are some resins that now approach ABS in strength and flexibility, but they are solvent based and require using IPA for clean up, and they apparently vary in odor. Your house may smell like a surfboard factory. Using water washable resins, run the printer on my Kitchen counter next to the sink. Absolutely no odor except a slight not unpleasant plastic/ new car smell. The shear strength is less than filament but it's still plenty strong. Those little parts in the firs picture are prop adapters. One end is screwed onto a motor and the other has a prop pushed on the end and held in place with a screw. The OEM adapter costs $3.99 plus shipping. Mine cost $.05 and are identical. They may not survive a serious prop strike but still flying with the first one I made. They are around 1/2" tall. There are 2 types of UV LCDs color and monochrome, and I was lucky and bought the monochrome version for $50 more and it prints in 1/4 of the time. The printer cost $250 delivered. I have had it about two weeks. I have been printing mostly accessories for RC Planes, Airbrush stands (BTW I have been airbrushing resolene, absolutely the best finish I have ever achieved!) and even some medical tools for my son's urology practice. I won't go into details but they can't get the device they use due to the virus and they factory has changed to making PPDs. They were paying $30 each, and my cost for the identical device is around $.10 https://www.amazon.com/gp/product/B08HLFZNWN/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 Bob Edited February 13, 2021 by BDAZ Quote
Members BDAZ Posted February 13, 2021 Author Members Report Posted February 13, 2021 The Celtic stamp was a success. I did some tests on another piece of leather and used my ton press cranked all the way and thee was no issue with cracking or crumbling. Bob Quote

Members HaloJones Posted February 20, 2021 Members Report Posted February 20, 2021 That is impressive, I have the Prusa SL1, my only attempt at a thing for the leather hobby, on it so far is for a logo / name plate - which snapped as I took it off of the build plate - my fault for laying it flat for a quicker print, but i was able to repair & use it. And yes the water based resins are so much better to work with Quote
