3D Printing Materials
PLA

Low Odor
Low Warping
Glue-able (Super Glue)
Renewable

• Weaknesses
o
o

Less Ductile (Brittle)
Low glass transition temp (parts easily melt/deform in heat)
PLA
• Bed Adhesion
o
o

Blue (or Green) painter’s tape (heated or cold)
Heated glass (40-60C)

• Layer Cooling Fan(s) required
• Resistant to most solvents
• Common uses:
o

Food packaging, disposable tableware, heat shrink film
PLA
• Printing Tips/Tricks
o
o
o

Increase temp when printing at high speeds (230-240C)
When printing small parts, print 2 at a time
To avoid jams, keep retraction to minimum effective length
because of thermal creep
ABS
• Acrylonitrile Butadiene Styrene
• Extrusion Temp: 220 – 260C
• Strengths

Impact resistant
Easy post clean up
Easily sanded & painted

Warps
Smelly
ABS
• Bed Adhesion

Heated Bed is required with all methods. 80-110C
Kapton/PET film
ABS “Juice” – dissolved ABS in acetone
PVA/ Elmer’s glue stick

• NO layer cooling fans
• Heated chamber if possible
ABS
• Printing Tips/Tricks
o
o
o

Brims/Rafts can greatly improve flatness
Higher infill = more warping forces
Ambient temperature can dramatically affect results (avoid cold,
drafty rooms)

• Common Uses:
o

Legos, 2-Liter bottle caps, automotive trim
Nylon
• Many different polymers available

Taulman 618, 645
Nylon 6
Nylon 6/9

• Extrusion Temp: 240-270C
• Strengths
o
o
o
o

Excellent strength with flexibility
Excellent interlayer adhesion (250C min)
Resistant to most solvents
High glass transition temp – heat resistant parts
Nylon
• Weaknesses
o
o
o

Warp
High extrusion temp
Very hygroscopic – Saturated in 18-24 hours

• Bed Adhesion
o

o
o

Heated glass (60-70C) with PVA glue or
glue stick
Garolite sheets – no heat
Wood/Plywood
Nylon
• Printing tips/tricks
o
o
o
o
o

Dry nylon prints smoothly and has glossy finish. Wet nylon pops
and hisses, has matte finish and weaker interlayer adhesion
Dry filament in 170F oven for 4-6 hours
Layer adhesion directly related to layer height/width.
Use solder knife or heated blade to “glue” parts together.
Flame polish with propane torch to eliminate any strings and give
glossy finish

• Common Uses
o

Trimmer line, toothbrush bristles, guitar strings
Laywoo-d3
• PLA with actual wood fibers
• Print Temp: 180 – 230C
(changes color)

• Strengths
o
o
o

Good smell (cookies)
Looks like wood
Sandable / Carvable

• Weaknesses
o
o

Softer when printed
Super low viscosity – strings easily
Laywoo-d3
• Bed Adhesion
o
o

Blue painter’s tape
Heated glass (40-60C)

• Layer Cooling Fan(s) required
• Hardens over time (48-72 hours)
Laywoo-d3
• Printing Tips/Tricks
o
o
o

Use lowest possible extrusion temp to prevent stringing
Increase speed to prevent stringing/blobbing
Allow to cool before removing from bed
Soft PLA
• Polylactic Acid – but flexible!
• Print Temp: 210-235C
• Strengths
o
o

Low Warp
Flexible

• Weaknesses
o
o

Expensive
Not durable
BendLay
• Modified ABS – clear & flexible
• Extrusion Temp: 220-250C
• Strengths
o
o
o
o

Stronger layer adhesion than ABS
Flexible
Optically clear, no distortion when flexed
Lower viscosity than ABS allows for faster print speeds
BendLay
• Weaknesses
o
o

Expensive
Only flexible when thin (single-walled or <1.00mm wall thickness)

• Bed Adhesion
o
o
o
o

Heated bed (80-100C)
Glass with hairspray
PVA glue
Do Not use ABS “Juice”
BendLay
• NO Layer Cooling fans

• Printing Tips/Tricks
o
o
o
o

240C+ gives optimum layer adhesion
Increase speeds 10-20% from ABS settings
Single and double wall thickness with minimal infill gives best clarity
Acetone causes filament to “crumble”. Brakleen (or other similar
automotive brake cleaner) is solvent
PETT (T-glase)
• PET copolymer (polyethylene terephthalate, aka polyester)
• Extrusion Temp: 207-235C
• Strengths
o
o
o
o

Clear, “optically correct”
Low warp
Excellent strength
Food-safe

• Weaknesses
o
o

Expensive
Low glass transition temp
PETT
• Weaknesses (cont.)
o

Requires slower print speeds

• Bed Adhesion
o
o

Heated glass (50-60C)
Garolite
PETT
• Printing Tips/Tricks
o Larger nozzles, >.5mm, give greater layer adhesion and
better clarity
o Increase layer height and decrease print speed. Vertical
resolution is still good at .3mm+ layer heights
o Increase retraction to avoid stringing
o Flame (quickly!) polish to remove “hairs”
