Sulapac Flow 1.7 is compatible with WASP’s large scale pellet 3D printers

Sulapac Flow 1.7 is a certified bio-based industrially compostable and recyclable material for 3D printing that was developed by Sulapac for the AM Industry.

The main components consist of wood sourced from industrial side streams and biodegradable biopolymers. All raw materials are selected in accordance with a strict sustainability policy, with the wood originating from certified forests.

The material has proven to exhibit excellent functionality in 3D printing, whether in filament or pellet form, producing extremely robust and stable parts as well as light, highly detailed objects.

WASP has tested this material with great results using both WASP 3MT HDP and WASP 4070 HDP, printing directly from pellets. Because of its certified sustainability and outstanding performance, Sulapac Flow 1.7 has entered the list of suggested materials for 3D printing compatible with WASP’s technology.

Containing 72% USDA bio-based content, this material is safe for both people and the planet. Sulapac Flow 1.7 has received BPI certification (ASTM D6400), proving it to be industrially compostable and leaving behind no permanent microplastics1 or toxic residue2.

1 Biodegradation of 76% in 420 days in the marine environment ASTM D6691 (86°F/30°C). Not considered biodegradable in California.

Ecotoxicity and threshold values for heavy metals tested according to EN 13432. All raw materials comply with the food contact requirements of the EU legislation.

The applications of bio-based materials in 3D printing

With its natural look and lightweight properties, Sulapac‘s bio-based material offers a great solution for numerous applications in various fields.

Furniture design is certainly one of the first applications that come to mind. We decided to test the printability and durability of this material by creating a 3D printed footstool using WASP 3MT HDP, the large-scale pellet 3D printer. We were pleased to observe how well the material performed with the machine, achieving a solid final structure along with excellent detail and an exquisite finish.

Thanks to WASP 3MT HDP‘s patented Firecap Sytem, it is possible to extrude the material at different temperatures and flow rates. This not only facilitates its extrusion but also makes it possible to give it different finishes, from smoother to rougher looks.

After the piece was printed, the Vacuum Retention System and flexible building plate made it possible to easily remove it without damaging its surface and structure.

Another excellent application suitable for smaller-scale use is packaging design. Meeting both EU and US FDA requirements for food contact materials3, Flow 1.7 is suitable for sustainable prototyping for cosmetic brands.

Depending on the circumstances, this material has the potential to replace PLA, ABS, and PP, and can even be utilized for manufacturing automotive parts, consumer electronics, and molds.

Restrictions and specifications of use apply, please refer to relevant Declaration of Compliance for further information.

Professional 3D Printing in large scale

Sulapac Flow 1.7 is compatible with WASP 3MT HDP, the large-scale 3D printer that prints directly from granules instead of filament. Thanks to its patented Firecap System and Vacuum Active Control, printing with pellets on a large scale has become easier and faster than ever, while also opening the doors to many new recycled and technical materials.
