lol the openGun thing is laughable, would any of you want to use a plastic gun that shoots bullets? I wouldnt, the chance of it actually being able to pull off 1 shot is very unlikely with FDM, and its probably only doable with laser sintering which wont trickle down to the public domain for another 20 or so years.
I love my 3D printer, its one of those technology that you dont need, but once you have one you ever think how you lived without one. I use it every day but then again Im a designer so I iterate ideas and use it for rapid prototyping purposes. These tools are pretty amazing, we just got back from an event called World Makerfaire in New York. Its amazing how kids who get exposed to these know so much already about 3D printing, and 3D modeling, and yet they are only 8-9 years old. Imagine what they can be doing if they had one of these they could use to bring their ideas to life. Its amazing times. I would love to see some photos of the 20 micron prints! I print at 100 and for practical use it is already very high resolution, let alone the time it would take to print an object that is 10cm talls.

I think the $20K machines by Object print at 16 microns so check picts there.
- for 3d models, Google's sketchup ( they bought out sketchup a few years ago) warehouse has lots of models though many are for architectural purposes. - they supposedly have new techniques that will increase the speed of print by orders of magnitude but it's still in the labs. ( eg. Vienna university researchers)... to be profitable with a home 3d printer, doing a diy cone skimmer or something like a mame part will get you the best bang for the buck as opposed to something like a chess piece. Let's hope the plastic is reef safe. msjboy

@msjboy The point is I want to see an FDM printer using thermal plastic print at 20 microns, not a resin based printer. I print at 100microns because its easily achievable with FDM, even 50 micron is doable. The problem is the nozzle of and the feedrate control that is associated with 10-20 microns are so fine that some printers have a hard time. The time associated as well is the reason why industry companies dont bother touching that resolution with FDM.
Doing home 3D printers is not just about our sw hobby, its much much more. But for our hobby even the plastics are 100% reef safe. PLA is bio pellets, so it will degrade in our systems so thats a no go. ABS on the other hand is lego, it is also fully safe. and I use it in my system and have printed things for friends as well. That includes the ability to print grid wheels that ATB came out with not long ago.

I'll see if I can find time to do up a 20 um print this weekend. The ones I do have I can't show because we are in the process of patenting the object. Yes, they take for ever.

awesome, maybe I'll adjust Ditto to print some stuff at 50 microns for some prints. Scubasteve hope you dont mind me asking are you a product designer? Ive meet a few locally but Vancouver has a small market for product designers. If you are it would be cool to know some exist on canreef!

I am many things. Currently I am finishing my PhD in Chemical Engineering at UBC while also running my own company where I am designing my own products for developing countries. I also design and machine one off prototypes for the odd side job here and there when I can find time. I came from a product/transportation design background before engineering but I am starting to make the transition back as I wrap up the PhD. So in a sense, yes, I am a product designer. I realize now how much I have missed product design, so I'm trying to find a way to ride this cusp of both engineering and design backgrounds and be something pretty unique.
How about yourself?
