Re: WHAT is going on? why? help please

Always keep in mind that thinner parts will need longer exposure time due to smaller concentration of light/UV. Also like mrelhashey says, add some pigments because transparent resin tends to have light bleeds and the concentration of the focused light will be less. Also very important is learning t...

Re: PDMS Breathe

Hello, for PDMS, all you need to do (if yo dont have a wiper system) is to pause the print, lift it and use some thing that fits the x or y of your vat and wipe across it a few times to let the PDMS get some air. Do it slow enough so that you can see through it. This seems to work well and you'll ha...

Re: Additional Pigment needed for FTD Deep Black?

Hi Joseph, Have you tried decreasing exposure time? I think the trick is to get just enough exposure to make sure the layers stick together and pulls off the vat. I'm in the same boat of trying to figure out the correct time...adding pigment will change the timing so you'll have to figure that out a...

Re: Additional Pigment needed for FTD Deep Black?

Hi Joseph, yeah it's too bad they dont sell pigment separately on their web site. If you buy SW you automatically get to choose a pigment color for no extra charge. To make gray I only used a little bit and still have a ton of black pigment for future usage. Hopefully they will update their website....

Re: Additional Pigment needed for FTD Deep Black?

Hello, Yeah so the difference between SW and DB is that SW has more pigment and does settles faster than DB. Now in terms of long print time, If you have a top down, it's definitely going to settle faster than using a bottom up printer, simply because bottom up tends to help stir up the resin more f...

Re: Additional Pigment needed for FTD Deep Black?

I was having similar issues with DB. I've since switched to SW + black pigment to make 50% gray and the bleeds are no longer an issue. I'm guessing that adding more pigment to DB cold help but not sure how much. Good luck and please keep us posted!

Re: Top Down 3D Printer

Hello and welcome! Looks like it could be settling issues where it's starts to cure when the resin is still moving and haven't settled. Try bumping up the wait time in between layers...mayb3 15000 or longer, depending on how viscous your resin is.
