Through the ongoing collaboration with Mitsubishi Chemical (MCPP) and BASF, two new standard 3D printing materials are now available from BCN3D. Tough PLA is impact resistant, stiff and easy to use. BVOH provides fast hydro solubility, use as a support material and wide compatibility with most filaments in the BCN3D portfolio. Recent collaborations with MCPP and BASF have produced two new materials to add to BCN3D’s portfolio: Tough PLA for tooling and end-use parts and BVOH for water-soluble supports.
“We are very excited to have two of the major chemical companies in the world as close partners. Their expertise in the industry and our combined capabilities in co-developing new solutions have proven to be essential,” said Eric Pallarés García, CTO at BCN3D
Tough PLA possesses the same qualities as standard PLA (such stiffness, a variety of colors and ease-of-use) but differs in the fact that it is tougher and stiffer. Tough PLA is engineered for its high impact and strength, similar to ABS, and with a stiffness akin to PLA. It is a plug and play material, shows excellent results in layer adhesion and has a very good surface quality. Tough PLA can also be easily printed using many different temperatures with no warpage or shrinkage.
This easy printability and competency in layer adhesion works well for functional prototyping. Tough PLA is also ideal perfect for both manufacturing aids and manufacturing tools because of its resistance to high impact and industrial feel, and its ability to perform as a standard material with more demanding properties. It works as an alternative to ABS for large prints as, in comparison, Tough PLA is stiffer, presents much less warping issues and is more 3D printing friendly as it doesn’t need an enclosed printing environment or emits any fumes which would require filtering.
Tough PLA will initially be available in colors black and white, with red and blue references available shortly. “It [Tough PLA] is really a great alternative to ABS and I would recommend it for applications that require high impact resistance, easy printing and excellent surface quality.” – Álvaro García Sabater, Product Manager
BVOH (Butanediol vinyl alcohol copolymer) is a thermoplastic optimized for the FFF manufacturing process. Its main advantage is its incredibly fast dissolution. This water-soluble material is easy to remove from inside small parts and reduces clogging issues as a result. It is compatible with PLA, Tough PLA, PET-G, TPU 98A, ABS, PA and PAHT CF15. Highly hygroscopic, make sure to store your BVOH in a sealed container to prevent moisture absorption.
BVOH is ideal for water-soluble supports for partially enclosed cavities and complex geometries, or even sacrificial moulds. When dissolving, the higher the water temperature, the faster the process. This makes it a great way of printing temporary support materials for complex geometries, such as structures with overhangs. It gives a smooth finish on functional prototypes and has excellent surface quality. With BVOH, movable mechanisms and hollow parts are also achievable, as well as multi-component models.
“BVOH is a complementary support material (PVA & BVOH) and I would recommend it for parts that need water-soluble supports, taking the potential of IDEX architecture; but also when a wider compatibility with our material portfolio is needed,” said Álvaro García Sabater, Product Manager.
The addition of Tough PLA and BVOH brings the number of materials available from BCN3D to a total of 9.
