Base Color without pigments - Form3?

Experimental
1

I want to print with Base Color without pigments on the Form3.
Does anyone have some experiance with that topic?

Hey there @Diana_Maryschka! Do you mind if I ask what’s drawing you towards dye-less Color resin rather than using our Standard White?

Hi Dan,
Standard White has to much pigments in the formula and so the light could not go thru our light objects.
At the time of the Form1 the White was with low pigments and now the Color Base looks exactly to that material.
So we want to use this material alone without any pigments to continue our products.
Is that possible with some modifications at the Form3?

Gotcha!

Well I just checked, and unfortunately it won’t work very well. The printer is tuned to print color with dye in it which offsets some of the laser’s power.

If you’d like to get more details and potential alternatives, you may get some advice here, or you should feel free to contact our support team at the link below and they’d be happy to help however they can.

I contacted the Support already but the only answer was to use another material.
Thats why i looking for “open mode” parameters to use the Color Base.

I know this doesn’t answer your question, but if you do decide to try other resins and want something with transparency between White and Clear, then Durable might be a good candidate. If you want to check out its color I’m sure you can get a sample from Formlabs.

I’m assuming you can’t simply thin the walls of your parts to compensate for the increased opacity of the latest White?

If you want to get experimental and push the boundaries beyond what Formlabs will support


Out of curiosity, have you tried just printing it with the Color profile and no pigment to see what happens? Or maybe a custom recipe with just a small amount of White pigment? I’m sure @DKirch is right that reducing the amount of pigment from 100mL won’t work as well, but you might find a sweet spot that’s ‘good enough’.

I also wonder if mixing a little bit of Clear in with standard White might be worth a shot to try and nudge up its transparency?

Finally, while you can’t adjust the laser power on the Form 3, you could try choosing a material profile that has a lower exposure power. Here’s some old data on that front. Though I’m not sure how easy it is to “trick” the Form 3 to print using a different profile compared to their earlier printers. Might require a Universal Cartridge. And like I said, none of these suggestions would be supported by Formlabs.
