Laser cutting 10mm acrylic?

[camhguh]

Thanks Robin,

yes, water jet cutting has intrigued me since i first heard about it but the machines seem expensive and then you have the abrasive material usage costs.

I did a lot of work on hydraulic production machinery at one time..injection moulding, template copying etc and the idea did pop into my head that i might be able to build one but that will have to be another project for another time i think :)

Desktop water jet cutting...way to go...

Can the abrasive be reused or does it just recycle until its no longer effective?

I think someone has to empty the filter tank once a year, supposed to be one pig of a job.

I did see someone offering a gizmo that separated out the garnet from the dross but no details.

I find milling acylic requires something to get the heat out, once it starts melting the tool bit is doomed. I usually just put the suds on. Icky.

Wonder if you can get an Abrafile blade for a bandsaw? That'd do it.

I've cut acrylic with the bandsaw and jigsaw, and the only way I've found to avoid clogging, is to cut as hard as you physically can. By that I mean full weight behind the jigsaw, and worry about not being on the line later!
