It is a biodegradable elastomer with a hardness of 32 D in the Shore scale. One of three members of our ecological line of filaments. Material can be stretched up to 500%. One of a kind - pure, elastic and biodegradable. The material works best with direct drive printers.

Available colors:

Core parameters:

  • low shrinkage,
  • easy, fast printing,
  • low printing,
  • does not require a heated substrate,
  • available dimensions: 1.75mm (± 0.03mm)


ECO FLEX is a biodegradable elastomer with a hardness of 32 D in the Shore scale. It is distinguished by high elasticity

ECO FLEX in difference to other flex materials is very easy to print. After exceeding the elastic limit, it stops returning to its original shape, but can be stretched even up to 500%. The material works best with Direct printers, which means, models directly delivering the lamentation above the printhead.

ECO FLEX is an ecological filament for 3D printing, perfectly in line with the principles of sustainable development and conscious production. Since it is made from plant materials, it is biodegradable (decomposes into lactic acid components, naturally occurring in nature). It is completely safe because rePLA it is even used for medical purposes, e.g. for production implants or absorbable sutures.

We believe in zero-waste

With time we realised that for the benefit of Our rePLAnet, we have to act more responsibly

The 3D printing industry is associated with rePLAstics, but it does not necessarily have a negative impact on the environment. In order to create more nature-friendly products, we have introduced appropriate changes which allowed us to reduce our carbon footprint.

However, we decided to go a step further. As a result of hard work, supported by many studies and tests, our company has created an ecological line of 3D printing materials. We intend to develop it on an ongoing basis, so that it can reach every home, workshop, laboratory or other rePLAces which, just like us, are ready to get involved in the fight for the environment and a better future.

Recycled wood fiber spools

When choosing the material for the spools, we focused on the material with a low CO2 emission. Our spools are made of recycled material, with 40% natural wood fibers. Wood has a negative CO2 emission factor, because a tree grows up to take CO2 from the atmosphere through photosynthesis. In this way, we have further lowered the product's carbon footprint. In addition, such a spool has a natural scent of wood and a pleasant-to-touch texture.

Cardboard recycled paper box

All of the materials are packed in environmentally friendly recycled cardboard boxes, marked with the RESY symbol. This mark guarantees the disposal and reuse of all of the transport and external packaging made of paper/cardboard. The marking complies with the requirements specified in the German act on transport packaging

An eco-friendly film and absorber

The spools are wrapped in 100% biodegradable foil and packed in an ecological, transparent, soft LD PE bag (polyethylene with the PZH approval, approved for contact with food and with the d2w Certicate attestation). The package includes a moisture absorber with bentonite clay - a completely natural product in the form of a sedimentary rock, containing mainly montmorillonite (a type of silicate). It absorbs moisture perfectly. After being absorbed, it does not dissolve, but swells (takes the form of a sponge).
