Basswood sheets or Taskboard for your model

The USF XARTS material guide (opens in a new tab) calls basswood a pale, smooth, fine-grained wood that can be cut by hand up to 1/8". It says a cut with the grain must be made carefully so the blade does not follow the curve of the grain. A cut against the grain takes several passes.

The same guide says basswood can be laser cut.

Basswood is hand cut up to about 1/8", says the USF XARTS guide (opens in a new tab). It also says a cut with the grain must be made carefully so the blade does not follow the curve of the grain, and a cut against the grain takes several passes. Use a sharp blade and a metal ruler, as the Academy of Art’s guide advises for any board (opens in a new tab).

Taskboard® has no grain, so the knife goes where you point it in every direction.

Labs accept it. The USF guide says basswood can be laser cut, Illinois’s DigiFab shop lists basswood among its approved laser materials (opens in a new tab), and Harvard GSD approves natural wood and veneer under 1/8" (opens in a new tab).

Expect dark edges and some soot. The University of Melbourne’s fab lab says laser cuts often need post-processing (opens in a new tab). xTool says masking tape on the material helps keep cut pieces from turning black, and to peel the tape off after cutting (opens in a new tab), and says you can try soap and denatured alcohol (opens in a new tab) to clean burnt areas. Taskboard’s edge is light brown, not black, and it sands clean.

Wood moves with the weather. xTool says its basswood plywood may deform in transport or from the weather (opens in a new tab), and advises holding thin sheets flat while you cut. Store sheets flat and buy only what the model needs. Taskboard stays flat.

Plywood is made from thin veneers with the grain alternating, per xTool’s product page, which can reduce directional weakness. A solid basswood sheet has one grain direction, so it cuts and splits differently along and across it. Check which one you are buying before you plan a part.

Pick basswood for frames, ribs and visible framing, where a stiff, real wood member is the point. Pick Taskboard for walls, floors, bases and any part you cut in many directions or many times, where a white sheet that sands clean saves finishing time. A model can use both.
