Factory-trained support, not a remote ticket queue. We size the mold, fill and release cycle to your part and target material. Sub-24h reply, NDA standard.
About this product
ALTANA Cubic Ink Mold 400 VP is a water-breakable casting resin that 3D-prints sacrificial molds for injection molding, casting and silicone work — then breaks apart in plain water, with minimal swelling, so parts release cleanly on an automatable cycle.
Why engineers choose Mold 400 VP
One-Shot Mold technology, not another castable resin.
One-Shot Mold (OSM) technology
The printed mold tolerates real filling temperature and pressure — up to 380 °C at the process and 1200 bar — so you cast in your target material, not a stand-in.
Water-breakable release
The cured mold disintegrates in water with minimal swelling. No mechanical breakout, no solvent baths — release is clean and repeatable.
Short, automatable cycles
Print, fill, release in water, repeat. OSM is built for short cycle times you can put on a production line.
Rigid & dimensionally stable
42 MPa tensile strength, 1900 MPa modulus and 80 Shore D hold cavity geometry, with 30/50 µm xy/z accuracy.

Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is One-Shot Mold (OSM) technology?
OSM combines a 3D-printed mold with the ability to withstand the temperature and pressure of real filling materials. You print the mold, fill it with your target material, then release the part by breaking the mold in water — enabling short, automatable cycle times.
How does the mold release the part?
Mold 400 VP is water-breakable. After filling, the cured mold disintegrates in water with minimal swelling — no solvent baths and no mechanical breakout, which keeps delicate geometries intact.
What can I fill it with?
It is designed for injection molding and casting with typical filling materials that require elevated temperature and pressure. For silicone injection, or if faster dissolution is needed, ask us about alternative Mold options.
Which printers is it compatible with?
Open LCD, DLP and mSLA systems. Specific parameter sets are available for Formlabs, Asiga, Prusa, Phrozen and Nexa; other machines run from the general process guide with application support.
How is it supplied and how fast does it ship?
1 kg and 5 kg bottles, made in Germany. Mold 400 VP is always in stock and ships in about 2 business days.
