PolyLactic Acid (PLA)• Glossy appearance• Biodegradable• Relatively rigid• No emission• Little
warping/shrinkage
• Useful for• Decorative items• Form and fit testing
Acrylonitrile Butadiene Styrene (ABS)• Matte appearance• More flexible than PLA• Prone to warping• May emit Ultra Fine
Particles• Variety of post-
processing options
• Useful for• Professional/industrial
applications• Toys/memorabilia
PET+• Strong and Flexible• Hydrophobic• Easy adhesion to Blue
Painters Tape• Flame Resistant
• Useful for• Professional/industrial
applications
Laywood• Recycled wood pulp
(40%) mixed with polymer
• No warp/shrinkage at all• 190˚C- Light colored• 230˚C- Dark colored• Can be processed same
as wood
Laybrick• Sandstone-like filament• Brittle• No warp/shrinkage• 190˚C- Rough surfaces• 210˚C- Smooth surfaces• Can be sanded and
colored• Ideal for large projects
NinjaFlex• Flexible filament• High elasticity• Sticks well to
acrylic/glass• Sticks too well to kapton
tape
• Used for• Mobile phone
casings• Wearables• Floatables?
Carbon Fibre PLA• Prints same as PLA• More rigid than PLA• May result in uneven
finishes
• Useful for• Performance parts• Prosthetics
Nylon – Taulman “Bridge”• High tensile strength• Transparent• Adjustable flexibility• Very little
shrinkage/warp• Adheres well to platform
with PVA glue
• Useful for• Industrial strength
parts• Mechanical parts
T-Glase• FDA- approved• No shrinkage/warp• Bridging capabilities• 100% reclaimable• Food containers• Jewelry
High Impact PolyStyrene• Dual extruder 3D printer
necessary• Dissolves in Limonene• Similar to ABS
Used mainly as support material
Polycarbonate ABS• Stiffer than ABS• Strong yet lightweight parts• Moisture sensitive• Prone to warping/shrinkage
• Properties similar to ABS• High resistance filament
• Useful for• Conductive devices• Solder-less circuits• Electromagnetic
shields• Project Ara
Conductive ABS Filaments
Other filaments?• Temperature Sensitive
Filaments• Bendlay• High Temperature PLA• Polyurethane• Carbon Nanotube-infused
Filaments• Graphene-infused Filaments• Igus 3D printing materials• Aluminium-infused filaments
