  1. Thanks for the tips. That was my 3rd print and subsequently discovered I have to crank the power down to 30% to prevent that. In fact, the client wants a very light print which is even faster and cleaner. The build area on this unit is only 3" x 3" and I have a small USB fan that does the job. I did play with the masking tape mask on wood to allow painting but that has given me the idea of using the laser JUST to cut the mask for stamped letters that I often paint, and this could cut the time to a fraction! Just have to get the depth correct and of course, only the outlines of the stamps. Thanks for that! The burn below is around 2"
  2. I just installed a flexible built plate and it's BRILLIANT! I print w/o supports whenever possible. Cheers! Bob
  3. A customer needed "Hand Made in Arizona printed small on the FLESH side of a large run of decorated coasters. Wet stamping didn't work, print through, a branding Iron was really expensive with long lead times and a rubber stamp would look crappy. So I bought a small laser engraver for $158, which arrived today, and I am as impressed as I was with the resin printer.. The Hand Made in AZ was maybe the 3rd print and a bit over exposed. But it's fine for the flesh side. The Celtic print is the same size as the stamp pictured above, on the grain side.
  4. These are the first few prints off the new laser. I still need to fine tune the power which is now at 25%. The Made in AZ took 4 minutes, and it's the size the customer wants. The Celtic rondel is around 3" in diameter and took around 30 minutes on the grain side. It was just a test but I'd knock off a few percent on the power setting. It was truly plug and play (Once you figure out how to convert the software from Chinese) and has absolutely solved the problem for +- $150. My workshop now smells like a dog crematorium, but the beauty of this engraver is that you can download the print to the unit, then disconnect from the PC and print anywhere there's an outlet. You could even place it in the middle of a hide. I intend to do my production work outside, and who knows, may keep the coyotes away (or attract them?!). I may even incorporate the laser for adding a "custom made for Fred Jones" which I have had requests for in the past. Average print times around 5 minutes for text. Bob
  5. Not following, but I just tested stamping the flesh side and it will bleed through on the 5-6 oz leather the customer wants to use. I think the only option is the laser. Bob
  6. The problem is that I am stamping the grain side and customer doesn't want anything else on the grain. I doubt that I can stamp the flesh side and not have a print through. I am stamping some samples now. I'll test it. Thanks! Bob
  7. Not enough margin to make it feasible, and it's a 1" x 2" text that just has to be legible, so not looking for the Mona Lisa. Just a quick and dirty imprint. All the hard work is on the grain side, custom stamp, etc. Used to worki in the wine industry in Santa Cruz and had many happy weekends in the Santa Rosa area checking out the competition. Engraver arriving tomorrow... Bob
  8. I have a large project where the customer wants to print some stuff on the flesh side of a custom stamped coaster. Clearly stamping the back won't work as it will probably print through, a branding iron with custom stamp costs as much as some of the cheaper lasers. A rubber stamp would look crappy and silk screening would also look crappy. I'm thinking this would do the job. https://www.amazon.com/Engraving-Machine-Desktop-Printer-Engraver/dp/B07Q8V4XV8/ref=sr_1_7?dchild=1&keywords=laser+engraver&qid=1617410988&sr=8-7 And suggestions or recommendations. I have lost work because the customer wanted an inscription so this may find occasional use later. I will probably end up making +- 1000 of these. Will the laser hold up and what is a typical print time for a 2 x 1 print? Thanks! Bob
  9. Around 3" and a total of 3/4" deep. I have had 5 projects using resin printed stamps to date which would have been impossible and unprofitable if I had to have the stamps made out of house. Best toy I have purchased in a long time!
  10. 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
  11. 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
  12. Update: My first leather stamp is printing, a Celtic knot pattern. Looks better than anything I have seen on Thingiverse. made from 2D art, extruded in Photoshop. Bob
  13. Too many other interests to get into something that's timer consuming with a learning curve. I am probably a week away from being able to print makers stamps. Bob
