Caverna™ PP

A polypropylene build material with a co-continuous, microporous morphology.

Price: $110.00 (1.75mm - 2.85mm)


Orders over 10+



The first in the line of unique Caverna build materials from Infinite™, Caverna PP (a polypropylene filament) has a water-soluble phase that dissolves to create a co-continuous, microporous morphology. After dissolution, the resulting material is soft and porous, and provides incredible moisture vapor transmission.

Printer Compatibility.

Caverna PP is available in 1.75mm and 2.85mm filament to meet the needs of most professional, industrial, and prosumer 3D printers. It’s been tested specifically on AON3D and Ultimaker S5 printers.

Material compatibility.

Caverna PP is compatible with standard, non-porous polypropylene, so users can create prints with selectively soft and rigid areas. And it pairs perfectly with AquaSys 120, enabling design freedom and easy support removal.

Printing Parameters

Caverna PP filament is designed for use in fused filament fabrication (FFF) printers.

Nozzle Temperature: 190-240°C
Build Plate Temperature: 95-125°C
Chamber Temperature: 20-50°C
Print Geometry: Gyroid for best dissolution
Adhesives: Print with a brim and glue on glass build plates. We recommend Dimafix glue.

The only way to 3D print a foam-like polypropylene.

Unique water-soluble phase.

When placed in plain tap water, Caverna PP's water-soluble phase dissolves to produce a co-continuous foam structure.

A perfect support partner.

Caverna PP is compatible with AquaSys 120, enabling design freedom and simple post-processing.

Excellent consistency.

Caverna PP's highly uniform pore size (1–4µ) and distribution provide outstanding print fidelity.

AquaSys 180 is in a class all its own.

No other support method can compete in terms of quality, convenience, or compatibility.

Caverna PP makes new applications possible.


From arm rests to hand breaks, many interior parts require soft, lightweight, and spongy materials. Caverna PP adds flexibility to their creation.


Consistent distribution of micropores makes Caverna a smart solution for advanced air filtration, improving internal cabin conditions.

Consumer products.

Due to its excellent filtration properties, Caverna PP could facilitate distributive production of highly effective 3D printed air and water filters.

Research & higher education.

When printed alongside a dense material, Caverna can open new doors in separation, extraction, and microfluidics with uniform, tunable design.
