3D Printing Material Guide
Not sure which filament to use? Here's everything you need to know about the most common 3D printing materials — from beginner-friendly PLA to demanding engineering filaments.
PLA
$Polylactic Acid
The easiest filament to print — biodegradable, low warp, and forgiving. The go-to for beginners.
Best for
PLA+
$PLA Plus / PLA Pro
PLA with improved toughness and reduced brittleness. Almost as easy as regular PLA with better real-world strength.
Best for
PETG
$Polyethylene Terephthalate Glycol
Stronger, slightly flexible, and moisture-resistant. A great step up from PLA for practical parts.
Best for
ABS
$Acrylonitrile Butadiene Styrene
Classic engineering plastic — heat resistant and tough. Tricky to print due to heavy warping. Needs an enclosure.
Best for
ASA
$Acrylonitrile Styrene Acrylate
Like ABS but with excellent UV and weather resistance. Ideal for outdoor functional parts.
Best for
TPU
$Thermoplastic Polyurethane
Rubber-like flexible filament. Great for shock-absorbing and grippy parts but requires a direct drive extruder.
Best for
Nylon
$Polyamide (PA)
One of the strongest standard filaments. Extremely durable and somewhat flexible. Demands perfect drying.
Best for
PC
$$Polycarbonate
The toughest and most heat-resistant common filament. Requires an all-metal hotend and a fully enclosed, heated chamber.
Best for
PA-CF
$$Carbon Fiber Nylon
Nylon reinforced with carbon fiber. Incredibly stiff, lightweight, and strong — used in professional and aerospace applications.
Best for
Silk PLA
$Silk / Glossy PLA
PLA with a silky, metallic sheen. Stunning visual results straight off the printer — no post-processing needed. Not structural.
Best for
Wood Fill
$Wood-Filled PLA Composite
PLA mixed with real wood fibers. Can be sanded, stained, and finished just like wood. Perfect alongside woodworking projects.
Best for
Metal Fill
$$Metal-Filled PLA Composite
PLA loaded with real metal powder (copper, bronze, brass, or iron). Heavy, polishable, and genuinely metallic-looking after post-processing.
Best for
PLA-CF
$Carbon Fiber PLA
PLA reinforced with chopped carbon fiber. Stiffer and stronger than PLA with almost no warp. Great for functional parts that need rigidity.
Best for
PETG-CF
$$Carbon Fiber PETG
PETG reinforced with carbon fiber — combines PETG's moisture resistance and toughness with CF stiffness. Excellent outdoor engineering filament.
Best for
PVA
$$Polyvinyl Alcohol (Water-Soluble Support)
Dissolves completely in water. Used as support material for complex overhangs when paired with PLA or PETG on a dual-extruder or multi-material printer.
Best for
HIPS
$High Impact Polystyrene (ABS Support)
Dissolves in d-Limonene. Used as a support material alongside ABS for complex prints. Can also be printed alone as a structural material.
