The materials
Everyday
Stiff, precise and inexpensive. Most indoor parts, prototypes and anything you look at more than you load.
The default. Stiff, dimensionally accurate, the sharpest detail on the machine, and every colour in stock.
- Heat
- Strength
- Impact
Good for. Holders, prototypes, patterns, jigs that stay indoors, dental and display models.
Not for. Hot cars, dishwashers, anything near an engine. It softens around 55 °C.
PLA specialty
Plus 10 percentThe same base with a finish in it: wood-fill that sands and stains, marble fleck, metal-look, glow in the dark.
- Heat
- Strength
- Impact
Good for. Display models and presentation pieces, anything where the surface is the point.
Not for. Fine detail with wood or marble fills; they want a 0.4 mm nozzle or bigger.
PLA with chopped carbon fibre. Much stiffer, a matte, fibre-flat surface, almost no warp.
- Heat
- Strength
- Impact
Good for. Stiff brackets and frames that stay indoors, drone and RC parts, fixtures.
Not for. Heat. It is still PLA underneath.
Tougher, and fine with water
A step up in toughness and temperature, and it does not mind water, oil or most cleaners.
Tougher than PLA with a little give, so clips flex instead of snapping. Slightly glossy. Good to about 70 °C.
- Heat
- Strength
- Impact
Good for. Brackets, enclosures, clips, containers, garage and bathroom parts, anything that gets wet.
Not for. Fine sharp edges; it strings a little more than PLA. Sanding.
PETG translucent
Plus 15 percentThe see-through version. Printed with thick walls it reads as frosted; thin walls let light through.
- Heat
- Strength
- Impact
Good for. Light covers, level indicators, windows in an enclosure, display pieces.
Not for. Anything that must be optically clear. It is translucent, not glass.
PETG with carbon fibre. Stiffer, tougher and better in heat than plain PETG, with a matte finish that hides layers.
- Heat
- Strength
- Impact
Good for. Structural brackets, tool holders that take a load, mounts that see some heat.
Not for. Parts that need to flex; the fibre takes the give out.
Heat and weather
Printed inside the enclosure, which is what keeps these flat. UV-stable and good to about 95 °C.
The outdoor material. UV-stable so it does not chalk or yellow, weather-proof, and good to about 95 °C. Matte finish.
- Heat
- Strength
- Impact
Good for. Truck and trailer parts, deck and fence hardware, garden fittings, engine-bay brackets, anything left in the sun.
Not for. Nothing much, other than price. If it lives outside, this is the pick.
The classic engineering plastic. Similar strength and heat to ASA, machinable, sandable, and it can be vapour-smoothed to a glossy finish.
- Heat
- Strength
- Impact
Good for. Housings, knobs, automotive interior parts, anything that gets sanded, glued or painted.
Not for. Outdoors in the sun; use ASA instead. It yellows.
ABS with glass fibre. Stiffer and more stable than plain ABS, with a matte surface.
- Heat
- Strength
- Impact
Good for. Fixtures and brackets that must hold a dimension in heat, larger flat parts that would warp in plain ABS.
Not for. Impact. The glass makes it stiffer but more brittle.
Flexible
Rubber-like. Hardness is graded on the Shore A scale: higher is firmer.
Firm rubber, about the feel of a shoe sole. Squashes and comes back, nearly impossible to break, grips well.
- Heat
- Strength
- Impact
Good for. Gaskets, feet, bumpers, grips, phone cases, hinges, belts, anything that has to absorb a hit.
Not for. Anything that must stay rigid or hold a tight dimension.
TPU 90A and 85A
Plus 40 percentSofter grades. 90A is a firm eraser, 85A is a soft gasket. Slower to print, and the detail is softer too.
- Heat
- Strength
- Impact
Good for. Seals, soft grips, vibration mounts, wearable pieces.
Not for. Small fine features or thin walls; the softer it is, the less crisp it prints.
Engineering
The top of what the machine runs. Dried, printed hot and slow inside the enclosure, and worth it when the part has to survive.
Polycarbonate
Plus 40 percentVery tough, stiff and heat-resistant to about 110 °C. The material for parts that take a hit near something hot.
- Heat
- Strength
- Impact
Good for. Guards, housings, mounts under the hood, light-duty gears, brackets near heaters and motors.
Not for. Parts that need a large flat base; PC likes to lift. We design around it.
Carbon-fibre nylon
Plus 60 percentPA-CF, PA6-CF and PAHT-CF. The strongest, stiffest, most heat-resistant material on the machine, past 150 °C, with a dry matte surface.
- Heat
- Strength
- Impact
Good for. Load-bearing brackets, jigs and fixtures, tooling, drone and robotics frames, anything you would otherwise machine from aluminum.
Not for. Parts that need to flex or take a sharp impact; stiff means less forgiving.
Glass-fibre nylon
Plus 60 percentPA6-GF. Nearly as strong as the carbon version, a little tougher, and easier on the budget for larger parts.
- Heat
- Strength
- Impact
Good for. Structural parts that see heat and vibration, mounts, brackets, fixtures.
Not for. The finest detail; the glass surface is coarser than carbon.
Carbon-fibre PET. Stiff, very stable, resists chemicals and heat to about 150 °C, and absorbs far less moisture than nylon.
- Heat
- Strength
- Impact
Good for. Precision fixtures, parts around fuel and solvents, anything that must hold a dimension in a damp or hot place.
Not for. Impact. It is the most brittle of the reinforced set.
Support and multi-material
Printed alongside the part and removed afterwards, so overhangs and internal channels come out clean.
PVA, dissolvable
Plus $15 per printWater-soluble support. The part comes out of a bath with no support marks at all, even inside channels and under bridges.
Good for. Internal channels, complex overhangs, mating faces that must be smooth on every side.
Not for. Large parts; it adds material and print time.
Dedicated support
Plus $10 per printBambu's support-interface materials for PLA, PETG, PA and PET. Breaks away cleanly and leaves a smooth face underneath.
Good for. Any part where the underside shows, or where the support would otherwise scar a fit surface.
Not for. Nothing; it is a finish upgrade, not a structural one.
A colour change by filament swap at a chosen layer, or a two-colour part with the AMS. Logos, text, a contrasting lid.
Good for. Branded parts, labels that must be read, colour-coded batches.
Not for. Full-colour graphics. Two to four colours is the practical range.
