Turn Your Polymer Prints Into Real Metal Parts
A vacuum investment casting system as simple as your polymer printer.
How it Works
3D printed polymer pattern​​​
A 3D-printed polymer part serves as the pattern that will be converted to metal. You can use any standard filament or resin printer, with either PVB, PMMA, or PLA filament, or a castable resin.
Create the mold​
Attach a sprue (a small wax stick that the metal will flow through later) to your 3D printed pattern and place it in the mold container. Our silica-free mold material comes in pre-packaged, water-soluble bags. Add water to the mixing container, shake it, and pour the mixture into the mold container to set. The process stays clean and dust free.
Take out the solid mold
After 45 minutes, the mold is solid. The flexible mold container allows you to remove the mold easily.
Place the mold into the machine
The lower compartment of the machine functions as the burnout furnace.
Add metal to the crucible
Place metal into the crucible. Any shape can be used, including scraps, ingots, or granules. Supported alloys include aluminum, zinc, copper, silver, and gold alloys.
Close the doors and press start
The system now runs the process fully automatically. First, the mold is heated to burn out the plastic 3D print. Then the metal is melted and cast under vacuum to ensure complete mold filling. An integrated exhaust gas treatment makes this process suitable for desktop operation.
Take out the filled mold
Once the cooldown phase is complete, the doors unlock. You can then open the machine and remove the filled mold.
Crack the mold
Place the mold in a plastic bag and crack it with a wooden hammer. The investment material breaks away easily from the part. For exceptionally fine details, you can use a brief cleaning bath to dissolve the last traces of residue.
Finished metal part
The result is a finished metal part requiring only 30-45 minutes of hands-on time. The entire process from CAD model to metal part is complete in less than 24 hours and can be done right on your desk.

Capture the Finest Features
The core principle of vacuum casting is the same as that used in the production of jewelry, dental components, and turbine blades.
This enables the AX-150 to replicate the finest features of your prints in metal.

About Aumatis​
​​
We are Aumatis, a technology company based near Munich, founded by Christoph and Felix.
Christoph holds a doctorate from TUM in Additive Manufacturing, and Felix is completing his doctorate in robotics. As engineers, we have worked with nearly every additive fabrication technology available. Over time, we became frustrated by a recurring bottleneck: while desktop plastic printing had become simple and accessible, producing custom metal parts was still slow, complex, and expensive.​​​​​​​​​​​​
​​​​​​​​​​​​The Problem We Had to Solve
​
Engineers often face the same challenge: waiting more than a week for external suppliers or dealing with complex, hazardous in-house systems. We focused on adapting a process the industry already trusts, investment casting, and making it usable in a modern workspace.
​
Traditionally, this process wasn’t practical in a desktop environment. But the rise of fast, affordable 3D printers provided the missing key: a way to create the high-quality patterns that casting requires.
Our Solution
​
Instead of inventing a new process, we refined a proven one for your desktop. Our system streamlines the entire workflow and automates the critical cycles: burnout, casting, and cooldown. Every part of the design is guided by the principle of ease of use. Inspired by the accessibility of modern 3D printers, we focused on addressing the primary barriers to adoption:
​
-
No Handling of Hot Metal: The process runs automatically behind a locked door.
-
No Dangerous Fumes: An integrated catalytic converter neutralizes emissions and prevents odor.
-
No Hazardous Dust: The silica-free investment material is supplied in water-soluble bags that eliminate dust exposure.

A system designed for the desk, not the foundry.
​
A Practical Approach to In-House Prototyping
​
The process turns a CAD model into a finished metal part in under 24 hours, requiring only 30 to 45 minutes of operator time.
FAQ
Exploring a Maker Version
Originally developed for professional use, we discovered our system isn't just capable, but also surprisingly fun and easy to use.
​
We believe it could be the perfect fit for passionate makers and small studios.
​
However, bringing this Prosumer version to life requires large-scale production. Before committing, we need to assess if there's genuine demand.
