    I've been looking at 3D printers for a couple of years now, and they've finally come down to a price range I can afford, so a couple of weeks ago I got one of these

    which is pretty cool, and can print up to a ~200mm cube. I want it mostly for pattern making as my woodworking skills leave a lot to be desired. So far I've modelled and printed the following bits ready to cast in ally:

    XS650 finned valve covers, because the chrome is on the way out, and fins are cool

    test prints at 1:1 scale for trial fit on the engine (the ones above are scaled by 2% to allow for shrinkage

    plus the latest thing off the printer

    3/4" tube bending die, sharpie for scale, so far this is the biggest thing I've printed, it took 18:30 hours, and has a 1mm skin and 20% density honeycomb interior. Layers are set to 0.1mm to improve surface finish, 0.2 is obviously quicker.

    A friend of mine has recently bought one , he said setting up is more involved than he
    thought , something to do with the correct temperature.
    It amazes me everytime he shows me a part , he just made a box that screws together
    and the threads are perfect .

    I found it pretty painless, 45 minutes from box to print, but I used the filament from the printer maker, I suspect I may need to tweek the variables a bit when I change plastics. I will be trying ABS and TPU (which is a sort of rubber) in a few weeks. I've looked at the data sheets for TPU, and I reckon it should be good for gaskets and possibly carb rubbers.

    Bloody hell, carb rubbers is a good one.
    Often a bastard to get hold of for an old bike thats long out of production and I hate K&Ns...Spit...
    Would cush drives be possible as well or is that too much tough service life for the avaliable castable rubbers?

    you can get castable rubber with variable shore hardness modifiers, this is one I know of, but there are others

    Making the molds can be done using plaster of paris, and masters can be done on the printer if need be. There's all sorts of possibilities

    Very impressed. It's the first time I've seen 3D printing useful and effective in smaller scale applications.

    I think a lot of people buy them as a cool gadget to play with, but I bought mine with solid plans for it. I've been developing my CAD skills to build models to feed the printer as well, so I've invested a fair bit of time into it.

    I do now... altho I'm not sure why one would need to create a pattern for something that already exists & can be on my doorstep tomorrow morning?

    However, if It was a case of "I have a spiffy new gizmo, I'm gonna bugger about for a bit & see what it can do" then no harm, no foul.
