Since recent move to Model resin I’ve been printing mostly small items at 25/m. Quality was acceptable but not impressive and definitely not better from Black V4. Only after I had to print few larger parts for a client, also at 25/m, I realized there is something seriously amiss with either the resin or my printer. Just look at attached photos. Part was treated with gray primer to better show features.
- Veins and bumps on surfaces
- Strange rings on supports
- Lack of sharp edges on facing down section
- Round holes are flatten at the top.
This reminds me of situation back in January and February 2020 when I was using Standard Gray resin and couldn’t print anything at 25/m or 50/m without horrible surface artifacts and poor resolution. Only after several consecutive updates to Preform those issues were mostly resolved. Not all but many improvements were implemented at that time. In fact later I switched from Gray to Black V4 as it seemed better optimized for highest resolution.
Now I feel like I’m back in time and very surprised at that. Is it possible that Model V2 is not properly set up for Form 3 printing. I’ve seen people getting good results with Form 2. Or could be there is another explanation for what causing it… I’d love to hear your opinions.
I can’t afford constant testing and retesting and need get moving on with orders. At this point I’m ready to go back to black which means I have to wash my resin tank and reprogram it to black. I’ve never done anything like it before. Would appreciate suggestions how to wash a tank and avoid causing any damage while doing it…
