Do I need this product?
The universal cartridge is developed to overcome “open mode” limitations. It enables you to print with exact the same printer functionality as original Formlabs resins. Users of the universal cartridge have experienced more consistent and accurate print quality compared to printing in open mode. Several manufacturers developed specialty resins which are not offered by Formlabs. They can now be printed using the full functionality of the machine. Some of the other “closed mode printing” advantages with the universal cartridge are continuous printing of >100ml parts without forced stops and weld lines.
Which resins are compatible with the printer and universal cartridge and what settings should I use?
Several manufacturers have developed resins specifically for the form 2. They can tell you which resin profile their specific resin is developed for. If this is not specified, a good starting point is using one of the standard resin profiles with the corresponding color of the resin.
Some manufacturers producing resins and are confirmed working are:
Photocentric, ApplyLabWork, Digital Forge, 3DResyn and Molecule.
Please note that while excellent results have been achieved, these resins and the universal cartridge are not recommended and not supported by formlabs. Use at your own risk.
What’s the latest firmware version that works with the universal cartridge?
We have tested the universal cartridge successfully until Firmware 1.18.12 – September 5, 2018
Is it difficult to install a module myself into an empty cartridge?
The modification requires a basic understanding of drilling and soldering.
To install a module, you need to drill three holes in a cleaned cartridge, solder two wires and glue the module in place.
How to use the universal cartridge?
The cartridge needs to be powered in order to work. Use a 5Volt USB power supply(eg. phone charger).
Module with round plug: First install the cartridge into the printer, then the cable and then power it.
Module with mini-USB plug: Insertion order is not critical.
When you need a different resin profile, do this using the available software.
