    Thanks for all the advice everyone. I think the bottom line is; don't do it yourself. It's better to get a company who has the proper laser cutting equipment to do the work... certainly for a hobbyist it goes against the grain a little, as I prefer having that whole end to end involvement on the creation of a part. But given the cost, safety and practicalities, it's just not sensible.

    It does mean however, there's a lot more pressure on the design being right first time. So my CAD'ing skills will be put to the test!

    Thanks all ๐Ÿ˜Ž

    The alternative is Water Jet cutting that produces clean (unburnt) cuts and has non of the problems associated with Lasers. Had all the cabin sides for the Titanic/Olympic cut this way and they were perfect. The supplier has since moved premises and I'm not sure if he still has access to the cutter.

    Hi redpmg!
    Just wait a little longer and then there will be such devices for us model builders at normal prices. .
    You're lucky to have something like this in the shop! At the moment these better devices are really expensive, unfortunately.
    You're right to pass this on to a company that offers such work.
    It is important to create clean DXF files or similar. this depresses the price of cutting.With basic laser cutters, your concerns about smoke and laser issues are correct. Don't skimp on these devices, the danger should not be underestimated if they are handled incorrectly.
    Hobbyist greetings Michel-Claude

    We use a large 600x900 high power Chinese laser for commercial purposes - luckily enough I am allowed to use it for model boats .

    With lasers its not worth buying a small one - or one too low powered. The open frame ones coming from China now are mostly underpowered and very dangerous . There is no provision to remove the smoke emitted when cutting - smoke alone can damage your lungs never mind the fact that a lot of it is toxic & highly dangerous - even MDF contains formaldehyde which is pretty nasty stuff . The minimal safety provisions on the the open frame ones are to say the least laughable .

    Minimum useful bed size is around 500 - preferably 600 - ( usually 600x 400 nominal - IE about 560x360 ). Minimum power 50/60w - preferably a honeycomb cutting bed - best beds are movable to allow deep objects to be cut or engraved - and lastly it MUST BE fully enclosed . There are a lot of nasty emissions from high powered lasers - its not just your eyes at risk.

    A separate cooler is required for the laser tube - and a good smoke extraction unit - in the UK I believe you would need to have an emissions filter system to remove the pollutants.
    Dodgy who used to be on this forum bought an open framed CNC router - its only really strong enough for balsa which was his main requirement - it generates a lot of dust ! - he was considering a laser attachment but looking at the risks decided against it.

    There are some desk top models available which might be suitable - but they have a lot of limitations like limited usage time before requiring a rest period - plus they cost very nearly as much as a full scale one and you still need the anti pollution unit etc which itself is expensive.

    There is a long list of items that should not be cut on a laser - learnt the hard way vinyl is one of them - emits a very corrosive toxic gas . See the PDF attached !!!

    All in all unless you have an ongoing use for the laser it would be better to outsource the cutting as the cheap ones can be lethal in many ways - (bear in mind even a 30w laser can easily cut a finger clean off ) and the good ones make an expensive toy !

    Hi all, Iโ€™ve a project going at the moment where Iโ€™m considering having some plywood laser cut.

    Wondering what experience members here have had with laser cutting wood, whether youโ€™ve bought a machine yourself to do it, or have sent a design off to another company. What is the better option?

    Just curious. Happy to take onboard any advice.

    Stephen
