The document (Annex XV1) released by the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) of the European Chemical Agency (ECHA) in 2019 was a first step towards final adoption. In Annex XV it was identified that 'intentionally added' microplastics are used in ...
The best glue is a PVA (polyvinyl-acetate) washable school glue. You have several slime activators (all in the boron family). These include: saline solution liquid starch borax powder These slime ingredients or slime activators all contain similar chemicals for making a slime substance. Cross-l...
People are continuously led to believe that PVA is 100% water-soluble and safe for the aquatic environment. However,the scientific study by IJERPHdisputed the claim that PVA is fully biodegradable. The research found that PVA acts as a pollutant in various negative ways. First, it sequesters he...
A great low-cost 3D print material, high-impact polystyrene (HIPS) is lightweight and impact-resistant, which makes it ideal for wearables and protective cases. Also called high-density polyethylene (HDPE), it’s dissolvable with chemicals, so it’s a great temporary support material for ABS ...

Biodegradable plastics are cleaved enzymatically in various environments, at times scales in the order of months to years, comparable to other natural organic materials. Water-soluble polymers like poly(vinyl alcohol) (PVA) cannot be considered biodegradable since the monomers will exhibit comparatively ...
(LCA) results. Since substantial energy demand is systematically addressed as one of the main reasons for ecological damage in FFF, mitigation strategies are often based on reducing the printing time (for example, adopting thicker layers) or the embodied energy per part (e.g., by nesting, ...

Wear safety gloves - chemicals can seriously damage your skin. Operate in well ventilated rooms as some toxic fumes may appear. Soluble Support Filaments: PLA vs ABS Since both ABS and PLA are very common materials for 3D printing, there’s a market demand for soluble support filaments. The...
Tough PLA is not as brittle as regular PLA, it exhibits higher tensile strength than ABS, is easier to print than ABS, and is compatible with the water-soluble support material PVA. Tough PLA filament properties Tensile Strength: 45-48 MPa ...
