PPprint GmbHthe German specialist offeringpolypropylene 3D printing solutions for professional, technical and medical technology applications announces a partnership with Ascent Manufacturing Inc., provide digital design and central manufacturing services for high-end prosthetics and orthotics. This strategic partnership allows US-based 3D printing companies in all industries to order the entire PPprintportfolio of polypropylene 3D printing solutions. International shipping costs and extended lead times will be eliminated through this collaboration.

New York-based Ascent Fabrication will not only be one of PPprint’s authorized resellers, but will also provide polypropylene 3D printing services to customers across the United States. Although their primary focus is to provide digital design and core manufacturing services to the prosthetics and orthotics industry, they welcome collaborations and offer printing services to other industries.

Ascent Fabrication is committed to providing innovative patient-centric solutions and will use PPprint’s polypropylene material in a variety of applications in the United States and developing countries. Joe Fairley, Founder and Certified Prosthetist, and his team have a diverse background in additive manufacturing, with over six years of experience.

People with physical injuries, reduced mobility or disabilities can use prosthetics and orthotics to live as independently as possible. Adaptive medical aids can improve a person’s mobility, level of function, and ability to perform daily tasks.

Given the wide range of physical limitations that people may face due to genetics, disease or injury, these devices must meet a wide range of needs while being adaptable to patient-specific criteria. ‘user. Adaptive medical aids are well suited for additive manufacturing due to patient-specific customization.

The three photos above, for example, show a custom 3D printed ankle-foot orthosis with support material that can be removed in a standard oven to produce the finished product. Filament P 721 black was used as the material for the ankle-foot orthosis, and support P 279 was used as the detachable support material.

3D printing of adapted medical aids

To successfully extrusion 3D print adaptive medical aids with polypropylene, three critical components are required:

Complete polypropylene (PP) 3D printing solution

  1. The printed material itself should have low warpage and high interlayer bond strength.
  2. The 3D printing surface should allow reliable 3D printing of PP parts and non-destructive, residue-free removal of the finished part without any additional chemicals.
  3. Support material is needed to print complex structures with overhangs and openings that can be easily removed from the finished part.

PPprint, a specialist in polypropylene 3D printing solutions, has solved these three problems and offers a range of complementary products. The current product portfolio includes the P-filament 721 PP filament range, which is available in 1.75mm and 2.85mm diameters. ‘P-filament 721’ is commercially available in eight additional colors, in addition to natural, white and black. Low warpage and high interlayer bond strength are two advantages of filaments. In addition, the 3D printed parts ‘P-filament 721 natural’ have been certified for biological safety according to DIN EN ISO 10993-5.

PPprint has also created the “P-surface 141” 3D printing surface, which enables reliable and repeatable PP printing. At high temperatures, 3D printed parts can be easily and flawlessly removed from the “P 141 surface”.

PPprint’sPolypropylene 3D printing solutions also include the world’s first detachable support material for polypropylene, “P-support 279”, in 2021, enabling the 3D printing of highly complex structures with bridges, openings and cantilevered. At high temperatures, the support material can be easily and cleanly removed from the printed part after the 3D printing process.
