Notes on materials

9.3.1

Properties

Material Properties
ABS High toughness.
Non-degradable.
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.
PLA Similar strength to ABS.
Biodegradable above 60 °C.
9.3.2

Soluble support structure

For overhanging model features, Axon automatically generates support material. To make
this support material easy to remove from the finished model it is possible to use different
materials for the build and the support. This is configured in Axon.
By using ABS build and PLA support, PLA support can be dissolved by:
 Leaving the model in an ultra-sonic tank with a small amount of caustic soda. Time
and concentration depends on the volume of the material needed to dissolve.
 Leave the model in water at 80 °C for over 48 hours.
9.3.3

Storage

All polymers degrade with time. The following conditions ensure the filament remains high
quality:
 Do not unpack until filament is needed.
 Store in a cool place: 2 °C - 15 °C.
 Keep away from UV light (e.g. sunlight).
 If machine is to left unused for an extended period of time, repack filament with
silica-gel sachet to maintain dryness (if present).
 Use within 12 months of receipt.
