Waterproof Plastic: Smoothing Beautifier

Waterproof Plastic: Smoothing Beautifier finish for 3D printed plastic parts

Posted By Marianna Papageorgiou on Oct 3, 2017 | 0 comments

Do you want to 3D print something in plastic, but you want it to be waterproof as well? Then we have the perfect solution for you! Our online 3D printing service is 3D printing plastic parts with  Nylon PA 12, and then we apply our unique post-treatment method to make them water-repellent: Smoothing Beautifier. It is very different both aesthetically and practically from the other finishing options Sculpteo provides: polishing, varnishing, dyeing or painting. Let’s have a closer look to this particular finish and see how it can meet your needs.


Waterproof finish for plastic 3D printing: Smoothing Beautifier

Smoothing beautifier is our patent-pending process developed by the Research & Development team of Sculpteo. This finish is applied on plastic parts, produced by our SLS (Selective Laser Sintering) 3D Printers, to give them a smooth and glossy surface. With this finish, 3D printed objects look like finished products!

Apart from the aesthetic improvement that it gives to the objects, Smoothing Beautifier’s as mentioned in some of our previous blogposts (Smoothing Beautifier portfolio for instance), it can also be a great choice if you need waterproof 3D printed parts!

In general, parts produced with SLS technology, are not water-repellent. Though, once the smoothing beautifier finish is applied, your 3D printed parts do not run any risk of absorbing water.

From R&D to creating a waterproof plastic finish for 3D printing

It took many experiments in the laboratories for the team of Sculpteo to develop this post-treatment procedure. In order to create this glossy effect, smoothing beautifier takes an exclusive physicochemical process to create surfaces that look as if they were made with plastic injection, which is applied on the surface of the part right after it comes out of the printer.

“We are proud to be the only industry processing 3D printed parts with the smoothing beautifier finish, providing such a high-quality result”, says Rima Lemmouchi, a specialist from the Research & Development team

In fact, the picture below proves that smoothing beautifier is applied to narrow the quality gap between injected molded surface quality and 3D printed part surface quality.

Waterproof 3D printing with our Smoothing Beautifier finish: Technical Parameters

Smoothing beautifier finish can be applied on any 3D printed part made of plastic Nylon PA12 of maximum dimensions: 140x250x90 mm and of minimum dimensions: 15x15x0.5 mm. Be careful that the part you wish to apply this finish on, should not be hollowed, as hollowed objects can’t have this finish applied due to the excess of powder inside the object that can’t be removed correctly. Moreover, for the moment, the smoothing beautifier is only available in white plastic, and in white plastic dyed in black.
