Polypropen material and three world records

Wematter Gravity Nanocellulosa 3D-skrivare

Wematter has set three world records that demonstrate the company’s innovative culture. It now offers Aurora polypropen material (PP), which is a rare type of material in the 3D printing world, for use in an SLS printer. The company has, moreover, created a powder out of its PP material, a second accomplishment.  The material, in either pellet or powder form, is made with nanocellulose derived from tree matter: the resulting material is  stronger than traditional PP.

Since its founding, Wematter has focused on a user-friendly SLS 3D-printer so easy to use that it can be placed in offices, hospitals, and laboratories.

This is a part of the team developing new materials at Wematter.

Another major focus has been on being a world-leader in materials development. To date, Aurora PA11 is the most commonly used material in Wematter’s Gravity machines.

The new PP material offers good mechanical properties and is unique. It is a rare material in 3D-printing in high demand. Wematter is capitalizing on the demand by joining the world’s very few PP suppliers for SLS printers.

Wematter is currently getting ready to go to market with its Aurora Polypropen powder. Preliminary data for this product may be found in the below product sheet.

The preparation of polymers in powder form is another achievement. PP powders, like Aurora Polypropen, can be used in powder bed machines, such as SLS or MJF printers. Wematter’s development team has produced a strong composite powder based on PP pellets.

From self-made plastic pellets with nanocellulose to polymer powder for SLS-printers.

And this is perhaps the biggest news: Wematter has created a composite powder, thus moving beyond the simple rarity of PP powders. The material contains nanocellulose, which grants the material stronger properties than its unmixed counterpart.

Wematter, as a Swedish 3D-printer manufacturer of highly advanced 3D-printers, has, with the help of Swedish partners, produced a powder that can be used in our Gravity machines. It’s been four tough years, but now we’re starting to see the light at the end of the tunnel.

The development of Aurora Polypropen

The new material was developed by a consortium within the framework of the Ampoform research project. ‘Ampoform’ stands for Additive manufacturing of prosthetic products based on raw materials from the forestry industry. The project is led by RISE within the framework of BioInnovation, and four companies have joined Wematter in developing this new material. Stora Enso contributed nanocellulose; Fillauer Europe developped prostheses; and Ortopedteknik/Örebro county works with orthopedic solutions for patients. Read more about Ampoform here.

Wematter has printed several different parts for prosthetics in different materials and the aim is to print demonstrators that can be used by patients in need of tailor-made sustainable prints.
