Best filament for lattice: thin walls and light weight

The short answerPLA for crisp thin walls. PETG for tougher lattice.

A lattice is a web of thin walls, so it needs a filament that prints clean strands and holds them together. PLA is the pick for crisp, light lattice. PETG is the pick when the lattice must take load.

What a lattice asks of a filament

A lattice is mostly thin walls and struts, so the filament must bridge and print clean at low flow. It needs detail and layer adhesion, not bulk. PLA prints the crispest thin walls. PETG is tougher if the lattice carries weight.

How the materials compare

When to pick PLA

Pick PLA for light, decorative lattice. It prints crisp thin walls at 200 to 220 °C with full cooling, and it holds fine detail. Use it for lamp shades, art, and any lattice that does not carry a load.

When to pick PETG

Pick PETG for a lattice that carries weight. It is tougher than PLA and bonds layers well at 240 to 260 °C. The trade is a slightly rougher thin-wall surface and more stringing.
