Impetus to Show Soluble Mould Cavities and Granule-Based Large-Format Printing

At Fakuma 2026, Impetus will present additively made mould cavities that dissolve after injection moulding, plus large-format printing from polymer granules. The company says prototypes can be produced within 48 hours.

Impetus Plastics Engineering plans to exhibit two development processes at Fakuma 2026 in Friedrichshafen. One is prototype injection moulding with additively manufactured cavities that are dissolved after moulding. The other is large-format additive manufacturing that uses polymer granules as feedstock.

Under the company's DissolveTool process, a printed cavity goes into an injection mould and is then selectively dissolved. Impetus says this removes the need for a conventionally built prototype mould and suits complex geometries, undercuts and two-component parts. The firm states prototypes can be made within 48 hours.

For large-volume parts, Impetus cites interlayer adhesion, warpage, dimensional accuracy and surface finish as key challenges. It runs an LFAM technical centre in Rosenheim for development and manufacturing trials. Impetus will appear at Stand 3123 in Hall B3 within the Hromatka Group joint stand.

For equipment buyers, ask whether printed cavities fit your existing mould bases and press sizes, and which materials can be dissolved safely. For large-format work, request trial data on warpage and layer adhesion for your intended granule grade.
