Hi, i am at the planning stage of a rather big model project, a 1:100 scale oil rig, right form the start it was obvious we will need some thin bits. Most things like railings and scaffolding will be etched brass, and most of the superstructure will be laser cut acrylic. we have a huge stock of 3-12mm acrylic in stock and some 2mm in 300x200mm sheets found at the local hobbyshop.

As mentioned i need thinner materials for many of the smaller details and i dont want to use cardboard, because it will warp over time. i have tried styrene with little success, polycarbonate with a bit more luck, however these are stinky materials and i dont get the neat edge the laser give me in acrylic.

So is there a material out there available in really thin formats (<1.5mm) that will work well with the 60w laser?

You can find Acrylic in 0.9mm and 1.1mm thickness, which cuts clean. It is the preferred material as most other plastics will melt too much.

MDF (1mm) or veneers (<1mm) are also available and may work too depending on the structure.

Generlly,it's no problem for the 80w to cut 8-10mm Arcylic,60w can cut 4-5mm Arcylic. Please contact with me by [email protected]
