Explore Caverna

Discover new applications with 3D printed foam.

Now available as a polypropylene (PP), Caverna build materials provide FFF users the only solution for creating thermoplastic parts with a co-continuous, microporous morphology.

Explore the untapped potential of porosity.

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.

By offering the ability to create parts that have an ultrafine, highly controlled network of tiny pores, all Caverna filaments — each of which will have a different thermoplastic base — will make new applications possible.

Here are the features that make Caverna so exciting.

  • Partially dissolves to produce a co-continuous, microporous foam-like structure
  • Compatible with AquaSys 120 for simple post-processing and greater design freedom
  • Highly uniform pore size (1–4µ) and distribution provide outstanding print fidelity
  • Loses 45% of its mass in dissolution, leaving behind soft, flexible material
  • Exceptionally breathable with an incredible moisture-vapor transmission
  • Enables the design of hollow, curved structures with a porous or filtering component
  • Available in two diameters to meet the needs of most professional and prosumer 3D printers
  • Uniquely suited to advanced filtration, porous tooling, and analytical chemistry applications

Co-continuous morphology: What it is, and why it matters.

By melt processing two polymers at near-equal parts, we’re able to create a filament with a co-continuous morphology — which is a consistent distribution of interconnected channels.

Caverna is a unique blend of two immiscible polymers: a soluble material to be removed through dissolution, and an insoluble build material to remain.

After dissolution, the water-soluble phase leaves behind a cave-like network of interconnected channels inside the build material, making it light, soft, and porous.

For automotive to medicine to aerospace – and everywhere in between.

From the sole of a shoe to tissue scaffolds to high-tech filters, the uses for Caverna are only limited by your imagination.

Automotive.

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

Education & research.

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

Rapid prototyping & end-use parts.

Caverna is easy to work with, allowing you to experiment more freely — and print complex geometries when supported with AquaSys 120.

Jigs & fixtures.

By using Caverna to create porous tooling, you can save time drilling holes and enable more even distribution in vacuum-formed parts.
