Permabond 3D10 et 3D30, new cyanoacrylate infiltrants for 3D printing

Permabond and Samaro expand their range of cyanoacrylate adhesives designed for 3D printing, with the new products Permabond 3D10 and 3D30.

The Selective Laser Sintering (SLS) process is a 3D printing technique that is more and more used for the manufacture of prototypes and 3D objects.

During the process, a roller spreads a uniform layer of powder (eg, polyamide). A 2D pattern is then drawn by a laser, which sinters the powder. Then, a new layer of powder is spread over the entire surface, and layer by layer, the process is repeated until the final piece is obtained. Once the part is completely manufactured, the excess powder is removed to obtain a solid object 3D printed.

The printed parts and prototypes are usually quite fragile and

brittle. A common technique to solidify and make them more rigid is to use an ultra-fluid cyanoacrylate bath (called “infiltrant”) and soak parts. Thanks to its low viscosity, the cyanoacrylate penetrates the pores, hardens the parts and makes them more resistant to shocks. After a few minutes of drying, the printed pieces are dry.

In the case of colored powders, the impregnation will also revive the colors to increase their intensity, and modify the visual appearance of the pieces by giving them a matte or glossy aspect.
