PLA (Polylactic Acid) $ Budget-Friendly

The most popular 3D printing material worldwide. Made from renewable resources like cornstarch, PLA is easy to print, eco-friendlier than petroleum-based plastics, and produces excellent surface quality.

Print Temp
190–220°C
Bed Temp
20–60°C
Tensile Strength
~37 MPa
Heat Deflection
~56°C
Density
1.24 g/cm³
Best for: Prototypes Display Models Cosplay Props Educational Projects Architectural Models Packaging Inserts
Pros
  • Easiest material to print — minimal warping
  • Wide color selection & finishes (matte, silk, wood-fill)
  • Low odor during printing
  • No heated bed required (though recommended)
  • Most affordable filament option
Cons
  • Brittle — can snap under stress
  • Low heat resistance (softens ~56°C)
  • Not suitable for outdoor or mechanical use
  • Degrades with prolonged UV exposure

PETG (Polyethylene Terephthalate Glycol) $$ Mid-Range

The "best of both worlds" filament. PETG combines the easy printability of PLA with much better durability, chemical resistance, and heat tolerance. It's the go-to for functional parts that need to last.

Print Temp
220–250°C
Bed Temp
70–80°C
Tensile Strength
~50 MPa
Heat Deflection
~80°C
Density
1.27 g/cm³
Best for: Functional Parts Outdoor Use Food-Safe Containers Mechanical Components Enclosures & Housings
Pros
  • Excellent layer adhesion — very strong prints
  • Good chemical and moisture resistance
  • Minimal warping compared to ABS
  • FDA-approved base material (food-safe potential)
  • Slight flexibility — won't snap like PLA
Cons
  • Stringing can be an issue — needs tuning
  • Slightly glossy finish (some prefer matte)
  • Not as stiff as PLA or ABS
  • Can be hygroscopic (absorbs moisture)

ABS (Acrylonitrile Butadiene Styrene) $$ Mid-Range

The classic engineering thermoplastic — it's what LEGO bricks are made of. ABS excels in heat resistance and impact strength, but requires an enclosed printer and good ventilation due to fumes.

Print Temp
220–250°C
Bed Temp
95–110°C
Tensile Strength
~40 MPa
Heat Deflection
~98°C
Density
1.04 g/cm³
Best for: Automotive Parts Electronic Enclosures Tools & Jigs High-Temp Applications Vapor-Smoothed Finishes
Pros
  • Excellent impact resistance — tough and durable
  • High heat resistance (~98°C)
  • Can be acetone vapor-smoothed for glossy finish
  • Lightweight (lowest density of FDM materials)
  • Good machinability — easy to drill, sand, paint
Cons
  • Significant warping — needs enclosed printer
  • Emits fumes (styrene) — requires ventilation
  • Poor UV resistance without coating
  • Higher print difficulty than PLA/PETG

TPU (Thermoplastic Polyurethane) $$$ Premium

A flexible, rubber-like filament that produces parts with excellent elasticity and shock absorption. TPU is the go-to when you need parts that bend, stretch, or absorb impact without breaking.

Print Temp
210–230°C
Bed Temp
40–60°C
Shore Hardness
85A–95A
Elongation at Break
~450%
Density
1.21 g/cm³
Best for: Phone Cases Gaskets & Seals Wearable Devices Vibration Dampeners Shoe Insoles Drone Bumpers
Pros
  • Extremely flexible and elastic
  • Excellent impact and abrasion resistance
  • Good chemical resistance to oils and greases
  • Doesn't warp or crack
  • Good layer adhesion
Cons
  • Difficult to print — slow speeds required
  • Stringing issues are common
  • Not compatible with all extruders (Bowden tube struggles)
  • Limited color options compared to PLA
  • Higher cost per kg

Resin (SLA / MSLA) $$$ Premium

Photopolymer resin produces the highest detail and smoothest surface finish of any consumer 3D printing method. UV light cures liquid resin layer by layer, achieving resolutions impossible with filament-based printing.

XY Resolution
35–50 µm
Layer Height
25–100 µm
Tensile Strength
30–65 MPa*
Types Available
Standard, Tough, Flexible, Castable
Post-Processing
Wash + UV Cure

*Varies widely by resin type — tough resins reach 65 MPa, standard resins ~38 MPa.

Best for: Miniatures & Figurines Jewelry & Casting Dental Models Precision Engineering Transparent Parts Master Patterns
Pros
  • Unmatched detail and surface finish
  • Wide variety of specialty resins
  • Isotropic strength (no layer-line weakness)
  • Excellent for small, intricate parts
  • Smooth finish requires minimal post-processing
Cons
  • Brittle (standard resin) — can shatter on impact
  • Smaller build volumes than FDM
  • Requires post-processing (washing & UV curing)
  • Uncured resin is toxic — needs safety precautions
  • Higher material cost per part (mL-based pricing)

How to Choose the Right Material

Just a Prototype?

Go with PLA — fast, cheap, and looks great for presentations and concept validation.

Functional Part?

Choose PETG for general use or ABS if heat resistance is critical.

Maximum Detail?

Pick Resin — nothing beats it for miniatures, jewelry masters, and precision parts.
