PLA (Polylactic Acid)

Polylactic Acid is one of the most common plastic used in Fused-Deposition Modelling, good for aesthetic models, draft prototypes and commonly used in cosplay costumes. As PLA is made from starch it makes this material biodegradable, incredibly viable for products in the market that aim to lessen waste pollution.

TPU/TPE (Thermoplastic polyurethane/Thermoplastic Elastomer

TPU/TPE are plastics which acquire flexible and elastic properties, with shore hardness ranging from 75A-95A. This material is commonly used in prototypes such as watch straps, bracelets, phone cases etc.

Polypropylene (PP)


A plastic commonly used in packaging, bottles and consumer products. It is a tough material but also displays elastic properties which allows it to be used for mechanical features such as living hinges. When 3D printed it can leave a shiny surface finish but when polished can produce a transparent surface finish, where transparency is dependant on the wall thickness.

Polyethylene terephthalate (PETG)


PETG is PET that has been copolymerised with ethylene glycol to make it more suitable for fabrication through FDM 3D printing; nonetheless it still acquires the same properties as PET. This plastic is commonly used in food packaging and containers due to its high chemical resistance. It is also acquires high impact strength.

Photopolymer resin is used in stereolithography (SLA) and Digital Light Processing (DLP) processes and is used for its high detail and quality finish as these processes can print to a resolution of up to 50 microns! Photopolymer resins can come in a number of types to match the purpose of the prototype; for example there is heat resistant resin used for prototypes that will endure high temperatures.


Castable resins are used to produce master models that will be then used to make master moulds, typically used in the dental and jewellery industry.
