Filament guideSome objects look wrong in shiny plastic. A lamp base, a desk organizer, a game piece or a prop for a set often wants the warmth of wood. Wood filament gets you most of that look straight off the printer, with no carving or finishing. Here's what Bambu Lab's PLA Wood is, how it compares to regular PLA, and where it works best.
Quick answer
The short answer
PLA Wood is Bambu Lab's PLA blended with fine wood powder. Prints come out with a matte, slightly grainy surface that reads as wood and hides layer lines well. It even gives off a mild wood smell while printing.
It's a look-first material. It's great for decorative pieces and display objects, but it's weaker than standard PLA, so it isn't the pick for parts that carry load.
01
What is wood filament?
Wood filament is not solid wood. It's regular PLA plastic (a plant-based plastic, the most common 3D printing material) with a small amount of wood dust mixed in. The plastic does the structural work. The wood powder changes the color, texture and feel.
Bambu offers it in six wood tones: Black Walnut, Rosewood, Clay Brown, Classic Birch, White Oak and Ochre Yellow. Bambu notes that color can vary a little between batches, since it depends on the raw wood and how it's dried. If several prints need to match, we print them from the same spool.
02
How does it compare to regular PLA?
The wood powder costs some strength. In Bambu's tests, PLA Wood is about as stiff as PLA Basic, but it's noticeably weaker when pulled, bent or hit.
| Bambu's test data | PLA Basic | PLA Wood |
|---|---|---|
| Tensile strength | 35 MPa | 26 MPa |
| Bending strength | 76 MPa | 55 MPa |
| Bending modulus (stiffness) | 2,750 MPa | 2,780 MPa |
| Impact strength | 26.6 kJ/m² | 15.7 kJ/m² |
| Heat deflection temp. | 57°C (135°F) | 57°C (135°F) |
Heat resistance is the same as standard PLA. Both start to soften well below boiling, so neither belongs in a hot car or near a heat source. For plain PLA basics, see our guide to PLA filament.

What PLA Wood is good for
- Planters, pen cups, trays and desk objects
- Lamp bases and decorative home pieces
- Board game pieces, tokens and boxes
- Architectural and product models with a natural look
- Props for photo shoots, theater and film sets
- Gifts and branded objects for studios, cafes and shops
04
What to avoid
- Load-bearing parts. Hooks, brackets and snap-fit clips are better in a tougher material like PLA Tough or PETG.
- Thin, fragile details. Bambu says a 0.2 mm nozzle isn't recommended, so very fine features are limited.
- Heat and outdoor sun. It's still PLA. Keep it indoors and away from heat.
- Damp storage. Bambu notes the wood powder makes it more sensitive to moisture, so we dry and store it carefully.

Tips for designing for wood filament
- Go a little thicker. Since it's weaker than standard PLA, give walls and thin stems extra material.
- Let the texture do the work. The matte finish hides layer lines, so organic and curved shapes look especially good.
- Mix it with other PLAs. Bambu says PLA Wood can be combined with PLA Basic and PLA Matte in one print. A wood-look body with a colored inlay is possible.
- Pick the tone for the setting. Black Walnut and Rosewood read as dark, rich woods. White Oak and Classic Birch read as light Scandinavian woods.
