This caught my eye the other day, and it’s an interesting piece of lateral thinking, which essentially creates a multi colour part by using a filament composed of different colours joining them in series so they are fed through a single head. The results look pretty good too, and it starts at $800.

We had a good look at this. It is very interesting but we weren’t confident in the quality of the joins in the filament.
Also it might be tunable to create multicolour prints in the same material but joining 2 different materials is likely to be too complex or impossible.
Similar to the new PLA + inkjet colouring printer from XYZ it can make pretty things but doesnt help with mechanical items, useable prototypes or engineering parts. “useful prints” is our target.
For official support please visit www.cel-robox.com/support/ and create a ticketI wondered about the joints but the thing that you missed @pete maybe was the joints are not used in the actual model. If you look they print a tower to purge the different colours, so you don’t get contamination, but you will use more material.
The joint is only to allow it to feed into the single head extruder. Interestingly, once you look at their forum you see people are joining different materials (obviously those suitable for this), and then the code tweaks the temperature etc for the different material.
One of the clever things is it could allow multiple colours with a restricted number of heads even on a Robox DM machine, assuming their was some correct post processing re nozzles and such. It does say it needs Cura or Simplify 3D slicers at the moment.
I don’t suppose you bought one and tested it out. 🙂
An extension of this approach would lend itself to a sealed reel environment, which has potential print quality benefits.
The Palette has just been upgraded to allow different materials to be used and to have more reliable joints. However, the way they work and the proprietary software and the needs for the printer may make it extremely difficult to adapt for use with the Robox. I was unable to figure out the workflow on mine after about 6 hours of studying the user manual and software, but they may have updated that with the new model.
The Palette uses a waste tower to clear the nozzle between colors/materials.
