Laser cuttable designs

Materials? Well, I suppose that all has to do with what kinda of builder you are and what kind of projects.

I'm a school educator and we mostly use 4mm baltic birch panels. The kids see lots of designs online and generate a few ideas of their own.

And a few times we will do some acrylic work.

Nobody is allowed to cut anything until they CAD it up first.

I'm new to laser cutting. I have tried different woods, fleece, felt, acrylic and leather (wet it 1st). I do use a wide masking on everything I cut to reduce scorching and smoke on my finished item.

try transfer paper too. it's used a lot for vinyl letter transfer. handy stuff, little easier to work with (IMHO) than masking, and usually less expensive than 12"30cm tape

Well I´am a mechanical engineer and have over 45 yrs experience in the steel construction. So i have constructed many objects im my life but using the basic elements like steel and Aluminium. In the last 10 yrs designing for the aerospace Industry using industrial Lasers

working with PET-G

This is awfully open ended.

Lasers dont cut all materials equally. The most obvious example is the amount of power required to cut aluminum vs mild steel. Its nearly double for aluminuum. As you get close to your machine limits you cut quality starts to degrade rapidly.

So...you work in a material your machine can handle. If you dont take that into consideration you shouldnt own the machine.

i am working with MDF,Acrylic,thin plywood,papers at thickness of 6 mm max.

I work with stainless steel because it needs no painting.

I build Giant scale RC planes. the best wood i have worked with is 3mm birch plywood . it cuts nice and has a lot of strength. of course i use balsa wood as well but the thinner the material you work with the finer cut results you will get. so try to laminate layers to build thick panels never try to cut material thicker than 6mm and expect to have neat cuts.

I work with Carbon Steel, the laser cutting allows me create designs more sophisticated and save time and money with in pre-machining operations.
