Kuraray develops soluble 3D printing filament

Kuraray develops soluble 3D printing filament

Japan’s Kuraray has developed a 3D printing filament for use in FFF (Fused Filament Fabrication) additive processes. The water-soluble, biodegradable filament is based on the company’s Poval polyvinyl alcohol (PVOH) resin, which is commonly used in adhesives, paints and coatings, wood primers, paper and textile applications, cosmetics and emulsions, among others.

The material sold under the Mowiflex brand has excellent adhesion to other resins such as polylactic acid (PLA), polyamide (PA), polyvinyl butyral (PVB) and thermoplastic polyurethane (TPU). Mowiflex filaments can therefore be used as a carrier material for 3D printed products that contain undercuts, moving parts and other complex shapes. Mowiflex is soluble in cold water.

Cold water soluble PVOH 3D printing filament can be used as a carrier material for making products with undercuts.

Implant-Grade PEEK Filament for 3D Printing Introduced by Evonik

Implant-Grade PEEK Filament for 3D Printing Launched by Evonik

In a world first, the material supplier Evonik announced today that it has launched a 3D printable implant polyetheretherketone (PEEK) filament for medical applications. The new material allows custom plastic implants to be 3D printed while meeting the requirements of ASTM F2026, the standard specification for PEEK polymers used in surgical implant applications.

The natural colored PEEK filament is wound on 250 or 500 gram spools, which are suitable for direct use in standard 3D printers for the production of melt filaments for PEEK materials. Image courtesy of Evonik.

The Vestakeep i4 3DF filament is based on the viscous, high-performance Vestakeep i4 G from Evonik. Biocompatible, biostable and radiolucent. The filament is manufactured under clean room conditions and is subject to strict quality management standards for medical materials.

The high-performance material was developed for FFF technology (Fused Filament Fabrication). The natural colored PEEK filament with a diameter of 1.75 mm is wound on 250 or 500 gram spools, which are suitable for direct use in standard FFF 3D printers for PEEK materials.

“For modern medical technology, the development of our first 3D printable implant material opens up new possibilities for adapting patient treatments,” said Marc Knebel, Head of the Medical Devices and Systems Market Segment at Evonik. “Orthopedics and maxillofacial surgery are examples of areas where this could be applied.”

Evonik also offers a test version of its PEEK filament, which has the same properties as the implant quality, but does not have the documentation required for approval in medical technology applications. According to Evonik, this offers a cost-effective way of adapting the processing properties of the high-performance plastic to a specific 3D printer.

Evonik offers an extensive portfolio of GMP-quality biomaterials for 3D printing of parts of medical devices that are designed for temporary and permanent body contact. In addition to Vestakeep i4 3DF, the portfolio includes the Resomer line of bioresorbable filaments, powders and granules for implantable medical devices.

Verbatim launches bio-friendly 3D printing filament DURABIO

Literally, a Japanese filament manufacturer of the Mitsubishi Chemical Grouphas introduced a new bio-based FFF 3D printing filament called DURABIO.

This material consists of Polycarbonate (PC) and polymethacrylate (PMMA) for optical and mechanical properties, high heat, scratch and abrasion resistance as well as high light transmission and UV resistance.

“Verbatim’s goal is to open up new markets in the 3D printing industry. An essential part of this is the introduction of special 3D printing materials developed by Mitsubishi Chemical with DURABIO This is the latest exciting addition, ”said Hidetaka Yabe, President of Verbatim GmbH.

A renewable, transparent technical thread

Mitsubishi Chemical initially developed DURABIO as a glass replacement. The bio-based engineering plastic is BPA-free and its main monomer is based on a renewable source, i.e. isosorbide, which comes from the commonly used sorbitol raw material.

The environmentally friendly properties of DURABIO have resulted in DURABIO being used in the automotive and mobile phone sectors for the manufacture of touchscreens, console and dashboard panels and radiator grills for outdoor use.

Mitsubishi Chemical added: “DURABIO was specially developed for applications that require exceptional permanent transparency and a visual appearance with scratch and impact resistance as well as chemical inertness.”

The filament will be available in transparent and high-gloss piano black and piano white. Bulk deliveries from DURABIO will be available from January 2019. New Verbatim products are expected to follow, including PET-G and high-speed PLA. DURABIO samples are also available at Formnext at the fair in Frankfurt, where the 3D printing industry reports live.

Earlier this year Verbatim filaments have been specially optimized for use in 3DGence 3D printers through a collaboration between the two companies. These included BVOH and Breakaway HIPS, water-soluble carrier materials for complex 3D printed objects.
