5. Print material
We support two print materials: PLA and ABS. Both have different properties and can be used in different build/support combinations. Typically, PLA
performs well as a build material with an ABS raft, and (if needed) ABS support.
PLA
PLA is a hard plastic with a low environmental impact. It is not a petrochemical - it is derived from renewable resources, such as starch. It is a
relatively new plastic and has excellent print characteristics.
As a build material: Good for large and small prints. Stable for 20 years up to 50 degrees Celsius
As a support material: Supports ABS well as it peels away easily. May be dissolved if required (see below).
PLA support can be dissolved by:
Leaving the model in an ultra-sonic with water and caustic soda. Time and concentration depends on the volume of support removal tank
the material needed to dissolve.
Leave the model in water at 80°C for over 48 hours. The
also provides this functionality. support removal tank
ABS
ABS is a well-known plastic with excellent toughness characteristics.
As a build
material: Good for small prints with high toughness requirements. Do not print area larger than 100 mm square – ABS has relatively
high shrinkage on cooling, and some geometries for larger prints are prone to warping.
As a
support
material: Supports PLA well as it peels away easily.
Material storage
All polymers degrade with time. The following conditions ensure the filament remains high quality:
Do not unpack until filament is needed.
Store at room temperature: 15-20 °C.
Keep away from UV light (e.g. sunlight).
