Laser cutter??


I'm looking to purchase a laser cutter for cutting model plywood. I noticed you can get 40W cutters fairly inexpensively, though they need to be upgraded with different controllers if you want to use Mach 3. Is 40W enough to cut through plywood and thin foam? Thanks.

It's difficult to say. Its debens of the glue the plywood have be made of.

I have a 50 watt laser. Somtime can i cut 2 mm and sometime 5 mm.

Balsa have no problems

Laser cut Ply Edges are a fair resemblance of a Charcoal Briquette. Black and dirty.
A Rotary tool makes a far nicer cut product.

do you guys know what is needed to cut the wood ...can the cutter be set up using a template of the part or does it have to be drawn in cad?

Cad drawings are exported to G code usually. The G-code translates to the controller card and the controller card tells the stepper motors the x y coordinates. I know someone locally that can cut the parts using a template with a water jet. He works with us and has a private business..
Or if you want, have your son give me the drawings to convert to CAD to send of to LDS or any other laser cutting companies.

That method is true for the CNC router I have access to, but the laser cutter PC drivers mean it is treated like a vector printer and will cut directly from Coreldraw- no need for the intermediate step of generating G code (still need a line drawing though, can't "print" a .jpg or the like).

Profili Cad etc has the capability to output as G code.
Easy and cheap for the package

You obviously haven't seen properly cut laser cut plywood. Done correctly, it's a nice light brown and no char whatsoever.

I wood think it would also.But the operator claims that they regularly cut wood. He claims they weight it down after cutting until it dries.
He has recently cut 12 kits of 6mm depron for foamy planes.
