Rapidia’s unique water-based technology revolutionizes how metal is 3D printed
Water-based from start to finish, the Rapidia metal 3D printing system is the simplest and safest way to create strong metal 3D printed parts. Water-based metal paste is solvent-free, safe to handle and unlocks a new world of opportunities for creating complex parts.
Clean and safe
Rapidia’s water-based metal paste technology is the foundation of the Rapidia metal 3D printing system. It takes the advantages of bound metal 3D printing a step further by accelerating the production process and doing away with solvents. The result is a fast, simple to use system that is environmentally friendly and completely solvent-free.
No debinding required
The Rapidia metal 3D printing system takes parts straight from printer to sinter, with no need to debind. Parts printed with conventional three-stage processes need to be prepared for sintering by dissolving the polymer binder, a process called debinding. This step can take up to 50 hours, and requires treating the printed part with a chemical solvent - a messy and dangerous process in an office. The Rapidia process eliminates debinding by using water to bind the metal powder, making the material safe to handle. The water evaporates during printing, saving time and removing the need for a debinding machine or solvents.
Evaporative supports for complex internal structures
The Rapidia metal printing system is the only one able to produce parts with complex internal structures, using proprietary evaporative polymer supports. These supports are unique to Rapidia, and are made possible by the water-based metal paste. By eliminating the debinding stage, polymer supports can be retained until the sintering stage, by which point the part is strong enough to support itself. These evaporative supports are used for almost all supports, substantially reducing post-processing time and cutting the amount of metal wasted on supports by up to 90%.
Water-bonding and sinter welding
Rapidia’s water-based metal paste is water soluble, enabling the unique ability to fuse unsintered parts together using only water. Complex assemblies can be created by printing simple parts and attaching them by dipping the area to be joined in water. After sintering, the resulting assembly is as strong as a single part. A similar process can also be used to sinter weld 3D printed parts to machined parts of the same alloy, using the Rapidia metal paste.
