HI all,

I’m new in SLA printing space (did most FDM so far), for a client I need to 3D Print in colored clear resin. Anyone experience with mixing clear resin with the color kit? As i don’t want to waste full cartridges, would it be possible to buy empty cartidges so i can make small volumes?

Thanks for feedback. I saw old post on this topic, but with very low to no response.  
Hans

I assume you are doing this with Form 4 and Clear v5 using color kit dye? Long story short it will work.

I can’t fully speak for clear v5 as I have only done with clear v4, but I cannot imagine the experience being that possibly different. It will work, you have two choices:

1. Put around 1/4 portion of what they advertise into cartridge, color obviously good for entire cartridge.
2. Put around 1/5 potion or less into tank, keep cartridge clear, good for some small prints.

This should give you a nice translucent clear color in that you seek. You probably have to experiment more as the dye is pretty strong with a clear resin as base. Given what you have said, I would recommend you dye JUST the resin in a tank, use a clear cartridge with nothing to finish several small prints, then toss the dyed resin and clean the tank and restore it to a pure clear tank.

Now… on the other hand, I have experienced the most dimensional accuracy with Clear v5 currently with severe part warping. Wonder what you have found with printing on Form 4?
