Ahhhhhh 3D printing, it be witchcraft I tell's ya....

As with any new skill, it takes time to learn the craft. Those with maker skills fare much better, but it's not going to be for everyone, bit like whittling spoons. :ddb:

Knocked the bedside lamp whilst fumbling for my glasses and thought I can do better than this.

My other half had picked up some usb flex LED lights. Aldi had just had a Powerbank on offer, so why not combine the lot into something useful. Sat down Friday morning with the bits and by Friday afternoon had the above. His and Her reading lights that should be good for 60-90hrs continuos use between charges. No wires, you can lift it out of the cradle and take to the bathroom if required, and its to hand but not in the way.

Since this turned out OK, print another one on Sunday to use as a desk lamp for craft work, macro photography or illuminating the microscope stage.

As I mention macro photography here's an example.

3D printed on a cheap machine. But why would anyone want to mould parts in silicon rubber. Surely machining them out of cast iron has got to be a better idea.... :palm:

Guy's, it's a relatively new technology for the home user. You do need some imagination to use it, but I think alot of people miss the point for how handy it is for prototyping, making parts to get you out of a fix quickly and complimenting other methods of making. Think of it like the early home computer, people would ask me what the heck do you want one of them for, what can you do with it. Well early on I had a hard time coming up with an answer, finally I got a job as a computer engineer and they stopped asking me what you do with it.

Hi Rob :wave: I have an injection moulder in the corner of the workshop.

Old Austin Allen Gnat. It doesn't get any use now I have moved onto 3D printing. No longer cost effective to do short runs, might as well farm out abroad :( Once the prototype has been approved.

Right, my broomstick has printed so I'm off.............

Particularly double-curved surfaces like small boat hulls and other relatively complex details that are fiddly to make by hand.
Think hulls, small phone booths, stacks of things, etc etc. The advantage with 3D printing is it requires a cad file as source nad the result will be as many bits as desired.

Peter this is what I am doing with what I find online as I'm crap at learning 3D cad as I seem to have trouble retaining what I learnt the day before. It prints nice and to smooth it I am looking at acetone smoothing. I have printed a sample to try it on (printed at0.01mm layer). Your printer should do what you want easily

:lol: :lol: :lol: Nice one Joules :Doh: ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, something you don't see often in the home shop :dremel:

The Silicon mould looks interesting , did you print the part and take a mould from that or just print the mould ?

This I thought was an excellent example of how 3DP can be put to good use , http://madmodder.net/index.php/topic,10491.msg120010.html#msg120010 .

Printed the mould Rob, as I wanted to see how it would come out. The contact surfaces of the mould were polished, note the rounding of the corners. The loop round the upper mould half slides down to locate the two parts, then I gently clamp them. Small holes in the upper half allow silicon to ooze out under pressure, I needed to use a pin to get the silicon into the narrow part of the mould around the vertical insert. With hindsight I would make this a push in part after the mould halves are joined. On my CAD system is a partially drawn model for an injection moulder using printed parts for the scissor arms and other parts, the idea is to use a 3D printer extruder for a desktop automatic micromoulding machine. Think 3D printer on its side with no X,Y.

This is my inspiration.

PPS, open to offers on the injection moulder if anyone fancies it.
