  • Welcome Manuel! You will find that the forum is a treasure trove of information regarding the Draken and how to use it. Feel free to ask any question you have on the operation of your 'new' printer and we look forward to seeing your printed work. :-)
  • When I speak consistency, it usually revolves around resin, FEP and build plate. The other part is model dynamics in terms of forces during peel (how much surface area, adhesion, etc.) All resin printers that are multi-purpose will run into these is…
  • I tried to do an experiment using both PFA and skivved teflon on the flex vat. I found the skivved teflon released easier than the FEP/PFA, but it is somewhat opaque, so there is a concern on fine detail. I hate to think I am still screwing around w…
  • I tried to do the static cling version of FEP using one of my 3Dfacture orange vats and I was getting resin underneath the film with two different types of film. While it does cling, I think the hydraulic force of the peel does cause the film to wri…
  • I am looking forward to more jewelry print results. If I can get the same quality of prints on Weaver with a smaller footprint than my Draken, I would be very interested.
  • @Andrew_3Dfacture it was a test to see if I could impart some of the sharper detail from the SolusCast resin while still getting the benefits of the cleaner burnout of the B9 Emerald. Since I didn't have a direct comparison of the same part, it was …
  • Did an experiment with 4:1 B9 Emerald:SolusCast Here is a closeup of the 4:1 mix detail (printed at ~30XY and 50Z - no antialias): I did a casting test with 3Dfacture castable, B9 emerald and the 4:1 mix using Optima investment and their bu…
  • Another good training video on how to re-do your PDMS in the vat. I will have to try the static cling version of FEP the next time I revitalize my vat. I've moved away from the flex vat due to some issues I was having with release and first layer co…
  • Not just silicone sealant, but any residual PDMS in the vat will cause the area around that residue to not fully cure. My worry about using non-adhesive FEP is that the pull forces of the resin to the FEP may be stronger than the cling forces of the…
  • Thanks Andrew - I hope you have a good Labor Day yourself! I know I am looking forward to having the day off. :-D Any new products on the horizon yet? 
  • It's been a while since I last updated my work. Here is a set of earrings I am making for the annual fundraiser for my kids school. and the final result when cast in sterling silver, assembled and the gemstones are set
  • Good video Gravelle!  The one thing I am not sure about is if near UV output tracks 1:1 against the sensitivity region of the photoresistor, but I don't think there is any reason to worry since you can adjust the exposure to compensate for it. It wo…
  • I will say that before I knew that I needed to adjust my exposure settings depending on which side of the vat I was printing on and now I can confidently print anywhere in the build area without adjusting the exposure. And that is worth every minut…
  • How does it work then when printing over the entire projection area? That is the real test of whether your mask works properly.
  • Great video and what a good mod!  It is easy enough to do and it doesn't require you to open up the projector body other than if you were replacing the light bulb. I like the purple glow. I should look into picking up some of that filter glass to se…
