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.

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.

Best 3D printing filament on a budget

Finest 3D printing filament on a finances

best
3D printing filament on a budget
Windows Central
2020

This list is meant to give you an overview of each material and the best product that you can pick up on a budget in each category. For my money, Inland PLA is the best you can buy for the cheapest price. It won’t let you down.

Note: This list is made up of 1.75mm diameter filaments as this is the most common width used by home 3D printers. Most of the products here are also available in 3mm diameter.

Polylactic acid (PLA) filament

PLA is the most common filament for beginners and general use. PLA is made up of organic polymers and is a biodegradable, rigid material with a low melting point. It is widely used as a base for models that you want to paint and for objects that are kept indoors. The downside to PLA is that in relatively low heat, around 60 degrees Celsius, or 140 Fahrenheit for US manufacturers, it can become soft and doesn’t do well in the elements.

Inland PLA is my point of contact when I want affordable, reliable PLA for large projects. When you dial it in, it has an almost matte finish that looks lovely on unfinished models.

Prusa, the creator of one of the best 3D printers available, has done something very special here. Prusament has amazing accuracy that allows for super smooth prints.

Acrylonitrile Butadiene Styrene (ABS)

ABS is used in many products around the world and is known for its high temperature and environmental resistance. It’s extremely tough even after it’s printed and can be wet sanded for a super fine finish if you want to take the time. The main disadvantage of ABS is its harmful fumes. If you plan to print in ABS make sure you are in a well ventilated place and use an enclosure if you can.

Thermoplastic Polyurethane (TPU)

TPU is the softest of the four filament types and can be used to make rubberized models such as cell phone cases or tires. It also works very well to create flexible hinges or protective covers when double-printed with another type of filament. TPU is usually more expensive than other materials so all is not under budget, but these are still your bargains.

Polyethylene terephthalate glycol (PETG)

PETG is the happy mix between PLA and ABS. It has the strength and temperature resistance of ABS while being safe to print indoors. Finding the right thing can be a little tricky, but once you do it you’ll never look back. You may need to use a Micro Swiss Hotend as PETG needs a very high temperature to print.

There are many opportunities

Choosing one of these products for the different types of material gives you a great chance of making great prints. Some work better than others on different printers, so it’s always a good idea to try different filaments until you find the right one for you.

I’ve titled the ones I use regularly as My choice because they give me the best results, but remember that all printers are unique so your mileage may vary.

For my money, Matterhackers’ Build series is an excellent choice for the full range of filament types. From ABS to PETG, the Build series just works.

You should also check out eSun Silk PLA if you don’t plan on painting your models. The glossy finish is just gorgeous on unpainted prints. The Moon City by Kijai Design above is a perfect example of how good the Silk PLA looks.
