There are a lot of exciting innovations coming to the consumer/prosumer 3D printing world surrounding multicolor and multi-material prints. Lets look at some of the upcoming options.
We previously covered the announcement of the E3D’s Tool-Changer which looks to have a great motion system and integrated tool-changer. E3D has an updated blog post with some additional details including some information on assembly, updates on build changes, and other minor technical details.
One of the most significant changes is with the frame to allow bigger tool heads. They’ve started manufacturing 30 to send to beta testers. Finally, there is some suggested pricing information depending on how manufacturing goes. Expect to pay at least $1800 for a full system (some of which will not come from E3D, like electronics).
Prusa Multi-Material 2.0 Kit
Prusa announced Multi-Material 2.0 kit a while ago and has been working on improving the design getting ready for shipment in what appears to be November now.
This kit allows up to 5 different materials to be printed in a single print. This means either multicolor prints or different materials like flexible mixed with PLA or dissolvable material mixed with non-dissolvable.
The Multi-Material 2.0 kit takes five filament feeds and, along with Prusa software, determines when filament needs to be changed. So a red, green, blue print would physically move the feeder to the current needed color. When the next color is required the Multi-Material 2.0 will cut the current color and move to the next needed color, feed it, and start printing.
The Prusa team is taking their time with this new product which I think is great. The previous multi-material kit had some frustrations for end users that look to be addressed with this update.
Pricing is $299.
Mosaic Palette 2 and Palette 2 Pro
Mosaic’s take on multicolor and multi-material involves figuring out how much of each filament type is needed throughout the entire print and then fusing different kinds of filament together to deliver a single line of filament to your printer.
Basic example: Say you have a model with red bottom and blue top. The Mosaic figures out how much red it needs then when the time comes for blue it fuses blue filament to the red all while continuously feeding your printer.
For more advanced model coloring or multi-material the Mosaic Palette does the same thing except multiple times depending on what color is needed in each part of the model. This could mean slicing red, green, blue, and yellow hundreds of times over the course of a multicolor print.
Mosaic has announced the Palette 2 series along with two other products to improve the user experience.
The Palette 2 is cheaper than the previous Palette+, and appears it is easier to access internals. With the newly added filament queue the Palette 2 can deliver filament faster than the previous Palette models.
Also announced from Mosaic was the Palette 2 Pro, designed for more demanding professional print situations. The CANVAS Hub which allows communication between the Palette 2 and your printer with the help of a Raspberry Pi. Finally they have created an online slicer called Canvas which currently makes coloring multi-part 3D models easy and provides slicing that is designed to work with the Palette series of accessories. In the future Mosaic has promised the ability to color 3D models that are not already split into parts.
Pricing starts at $499
Which one makes the most sense?
For multicolor prints, all three will get the job done (note the Prusa Multi-Material 2.0 Kit needs a Prusa MK2.5 or MK3 printer). I have not tried any of these (none are actually shipping yet) but on paper it looks like the Mosaic Palette 2 would provide the fastest multicolor solution because filament being supplied to the printer is continuous.
For multi-material prints, on paper, the E3D Tool-Changer would be the best option. You could have wildly different materials like Nylon and PVA because each material gets its own dedicated tool head. This means the Nylon head can maintain the desired temperature without adversely affecting the PVA.
The next best option, on paper, is probably the Prusa Multi-Material 2.0 kit if you have a Prusa printer. The direct feeding of five different materials allows for the tool head to change temperature as needed although with a delay compared to the E3D Tool-Changer.
Finally the Mosaic Palette 2 will be able to print multi-material as long as the two materials are within 10 to 15 degrees Celsius of each other’s preferred printing temperature. This rules out some combinations of materials people might like to use.
For Prusa MK2.5 and MK3 owners, on paper, the Prusa Multi-Material 2.0 kit gives you multicolor and multi-material printing for the lowest price. If the kit turns out to be well designed and it performs as expected, it will be the go-to choice for owners of Prusa printers. As a runner up, the Mosaic Palette 2, would also work on a Prusa printer.
For the future and crazy ideas, on paper, the E3D Tool-Changer is the only option. Keep in mind this involves building a whole new printer that, in total, will cost at least 3 times a Prusa MK3. That said, if you want to have a fine print .25 nozzle combined with a volcano that does .8mm infill, or a pick-in-place tool head, laser engraving integrated into your work flow, or some other crazy idea for a tool-head, your only option is the E3D Tool-Changer.
When can I get it?
The Prusa Multi-Material 2.0 Kit is shipping very soon. Probably in September. The Mosaic Palette 2.0 is expected to start shipping in October. The E3D Tool-Changer will ship when it’s done, which I suspect will be November-December or later.
What do I need to know?
- The Prusa Multi-Material 2.0 Kit and the Mosaic Palette 2 will require purge towers. This allows the printer to get the next color or material ready when there are changes during a print. On paper the Mosaic Palette 2 might have a smaller purge block, but we will know more once it comes out.
- The E3D Tool-Changer will not have purge towers but it will have to purge and wipe the nozzle before and after printing each color or material type. This is done at the sides where filament is pushed out then the nozzle is wiped across a brush. This will slow down prints and waste filament just like the two products above.
- The Mosaic Palette 2 will only work with 1.75 filament.
- The Prusa Multi-Material 2.0 Kit is the cheapest option by at least $200.
- The E3D Tool-Changer will require some advanced knowledge and experience with 3D printers, firmware, and tweaking to get running. Your costs will be at least $1800 since it does not include required electronics.
