Multi-material printing lets one print include a rigid body, a flexible seal and soluble supports, so a prototype comes off the plate closer to its final form and needs less assembly. Quadro's four independent toolheads can hold four materials at once, each at its own temperature, which makes mixed-material parts practical.
For prototyping, the value isn't color. It's materials and time: fewer separate parts, fewer assembly steps and fewer iterations to learn something.
What Multi-Material Prototyping Can Do
- Rigid with flexible. A housing with a printed gasket or a grip in TPU, in one job. See One Print. Four Materials That Don't Get Along..
- Moving assemblies. Print-in-place mechanisms where soluble supports fill the gaps, then dissolve. See Soluble Supports (PVA).
- Color-coded prototypes. Parts, zones or tolerance fits marked in color for review.
- Carbon-fiber reinforced filament. Quadro's materials include PLA-CF for stiffer parts, with the nozzle recommendations in Nozzles for Quadro.
Why Independent Toolheads Fit
Each toolhead keeps its own material loaded and its own temperature, so printing a high-temperature and a low-temperature material together doesn't require the compromises of a shared nozzle. Nothing is purged between materials, so there's no cross-contamination from a previous material. See How Quadro Coordinates Four Independent Toolheads and Why Quadro Doesn't Purge.
Accuracy Starts with Alignment
When two materials meet at an interface, how well their toolheads are aligned decides how well the parts fit. Automatic calibration aligns all four, and a rigid structure keeps them aligned. See How Quadro Calibrates Four Independent Toolheads and Bed-Slinger Simplicity. No Bed-Slinger Flex.
Size and Environment
A 300 × 300 × 300 mm build volume fits larger housings and fixtures in one piece, see No More Splitting Large Models. For temperature-sensitive materials such as ABS, an enclosure helps, and an optional add-on will be offered. See Open Frame, Enclosure Add-On.
Know the Limits
A desktop printer prototypes, it doesn't replace production tooling. Material properties of printed parts depend on the filament and the settings, so test a prototype under real conditions before relying on it. Check the material manufacturer's guidance when two materials need to bond.
Key Takeaways
- Multi-material prototypes reduce assembly steps and iterations.
- Four independent toolheads hold four materials at their own temperatures, with no purge between them.
- Calibration and a rigid structure decide how well interfaces fit.
- Validate prototypes under real conditions.

3. FAQ
Can Quadro print rigid and flexible materials in one print? Yes. Each toolhead holds its own material, so a rigid material such as PLA or PETG and a flexible one such as TPU can print together.
Can I print moving assemblies in one piece? Yes, with soluble supports. PVA supports fill the gaps and dissolve in water, which frees the moving parts.
Which materials does Quadro support? PLA, PETG, ABS, TPU, PLA-CF and PVA.
Is a multi-toolhead printer accurate enough for fitting parts? Accuracy depends on alignment. Quadro calibrates its four toolheads automatically and is built on a rigid structure, but test your own fits.
Is this a replacement for production tooling? No. It's for prototypes and short runs. Test parts under real conditions before relying on them.
