    This thread is for posting of requests for laser cutting work. If you've got you can help out fellow members with or or would like something cut...here could be the place to find it!

    There is a thread already for 3D printing requests, and I thought it might be good to offer laser cutting as a service also. Maybe someone could make one for routing also?!

    Hopefully those on the forum that own or have access to a laser cutter will be able to respond to the request and give an idea of cost and whether they can take on the job.

    So if anyone has equipment and happy to help out like the 3D thread, post away! :)

    ---

    I have a 50W Co2 laser cutter in S/W Sydney, 500x300mm cut area, happily cuts up-to about 6-7mm, can do MDF, plywood (can be a bit iffy with the glue in the ply making cuts trickier), acrylics, cardboard etc. Engraving also possible.

    Happy to cut work provided in vectors/dxf/svg etc, would work on used space of the bed rounded to 1/2 or 1/4 increments etc of material also depending on the material and cost etc (or you can send/drop off material)

    I think a fair method would work on cost of material (Bunnings for wood) plus postage (or pickup) and say $20 per bed size for cutting, similar concept to the price-per-gram for the 3D printing thread.

    I currently have 3mm and 6mm MDF sheets and 7mm plywood and a few examples of things i've made/making:

    Is cutting and engraving things like perspex GPU backplates a possibility?

    Thats something I would definitely be interested in.

    I think pricing wise you'd be best on material + time. Most commercial mobs do it by cut distance (which essentially equals machine time), do you do it that way if you can easily work out the cut distance.

    Can you or anyone else do aluminium?
    Looking to get some small pieces done in 0.5-1mm thick (less than A4 size)
    And some large parts out of 6-8mm (less than 2m x 1.5m)

    Cheers.

    2m x 1.5m ? thats pretty big... you might want to go to a commercial joint for that

    If you are just cutting alu you may want to go down the path or routing rather than laser, better finish and usually cheaper

    I have a commercial laser cutter and router in mind they just charge a lot for one offs. Either laser or routing will work if anyone here can help out.

    I operate a 4kW fibre laser.

    We can cut up to 16mm thick mild steel, 10mm stainless, 6mm aluminium right down to paper thin metal, area is 3000x1500mm. This machine will etch outlines only, we're not setup to do shaded etching.

    I'm happy to do one offs and freight to you, we're in Launceston, Tasmania. Shoot me a PM with a drawing or dxf / dwg file and we can come up with a price that works.

    Here's an ant I cut earlier today from 12mm steel

    Does anyone know any software that is good at generating text on path, other than Adobe Illustrator, that can save as dwg or dxf? Last time I tried AutoCAD (~6 months ago) it wasn't good at this, and DraftSight can't do it either although I'm running an old version for Windows XP, that will change next week when my work PC is upgraded to Windows 7 and I can run DraftSight 2015.


    Anyone want an overclockers.com.au sign from 8mm mild steel?

    I'm another member that works at a laser cutting company -- based in Dandenong.

    We have a $100 minimum charge.

    Mild steel up to 20mm, stainless up to 16mm, and aluminum up to 12mm. 3x1.5m sheets.

    Acrylic/MDF/whatever up to 30mmish.

    We also offer folding up to 3 metres long, and have a Yag laser for filled marking up to 180x180mm.

    Moon what happens to the material if you go thicker?

    I don't know enough about the technical side to give an answer, I'd just be making something up.

    An easy way to screw up your cutting is to move too slowly, or too quickly. I imagine the speed at which you need to move through the material becomes too high for the available amount of power you have for heating the material.

    The slower you move, the worse the edge quality - a lot more striations up to the point it will look like a hand held oxy cut. The molten material will dwell at an exit.

    If you are cutting faster you can get closer to what looks like a mirror finish on the edge. The problem here is you are generally on the verge of cutting too fast, and once that happens you will have incomplete cuts and dross on the back of the part.

    Is that by chance a Bystronic brake press? :lol:

    I was hoping there were enough laser cutters in Dandenong that no one would be able to work out the company. Although there are probably others with bystronic brake presses.

    Although, with you being in Adelaide...
