3ders.org – Extrudr unveils new Inexperienced TEC 3D printer filament constructed from renewable and pure supplies

March 9, 2016 | From Alec

With the 3D printing community consuming huge amounts of plastic (and how many of those prints fail?), It’s always good to use 3D printer filaments that are biodegradable or can be recycled. PLA is a good start, but is only fully biodegradable in bioreactors and under certain laboratory conditions. Grinding units are another option: machines that can be used to recycle faulty prints into new 3D printer filaments, although unfortunately these are still very expensive. Fortunately, a third option has just appeared: Extrudr Green-TEC from Austrian 3D printer filament manufacturers Extrudr. In contrast to PLA, it can be 100% broken down in natural cycles.

If you’ve never heard of Extrudr, it’s likely because they haven’t been around long. Although they have turned up here and there at some 3D printing and event events, they are actually a very young manufacturer from Austria who has been working on their products since February 2014. Although deciding on a new manufacturer can be a bit daunting since you don’t know what you’re going to get, co-founder Johannes Früh previously told 3ders.org that they have a high quality production line. “We can guarantee high quality standards such as diameter, resin, roundness, printability, etc.,” he told us.

While very young, they have already developed a diverse line of 3D printable filaments, including various brightly colored (and multicolored) PLA and ABS options, a range of PETG filaments, and some biopolymers. At the beginning of the year they also let shine in the dark, woody and pearl-like 3D printer filaments.

They are now adding Green-TEC in four colors to this line: black, blue, red and white. As they explain, it is made entirely from biological compounds and pure raw materials. “The material has a bio-organic composition and compost mixtures in contrast to PLA,” they say. “Green-TEC is therefore CO2-neutral and absolutely harmless from an ecological point of view.” It is an excellent alternative to the more conventional ABS or PLA filaments, and not just because it is environmentally friendly. It is also non-toxic and has superior temperature resistance, hardness, and elongation compared to ABS or PLA.

It is also easy to use – unlike ABS, Green-TEC 3D printer filament hardly suffers from shrinkage or warping. This makes it very suitable for larger and more complex prints with a large surface area. It doesn’t even need a heated print bed. And because it meets all EU regulations for plastics that come into contact with food, you can also use it on a wide variety of 3D printed products. While it’s slightly more expensive than other filaments at € 56 per kilo (or around $ 61), its eco-friendly properties are particularly attractive. It is also available in 1.75 and 2.85mm options.

Specifications for Green-TEC filaments:

  • Heat resistant up to 110-120 ° C, 248 Fahrenheit,
  • Low temperature of 170-200 C.
  • High mechanical resistance, which leads to lighter components

  • Biodegradable
  • High layer adhesion and good optical properties
  • Print parameters
  • Printed bed: 0-60 ° C.
  • Adhesion: Bluetabe, Kapton, Carbon, Glass
  • Print speed: up to 120 mm / s

Weight:

  • 1.75 mm – 2.4 g / m
  • 2.85 mm – 7.6 g / m
