The post whore thread.

Well well well!

I missed you my bearded fellow. What's the skinny?

Well, my face is no longer bearded. That disappeared a long time ago actually.

I moved cross county with a 2 week old baby. She did better than we thought thought. Have gotten to play with and be sent to training to learn how to use some super fun toys at work. The department has had a 3D printer for 2yrs and I'm the first one to actually use it beyond pulling it out of the box. What did I print? I spent about 1mo printing (and failing lots) parts to build myself a 3D printer (RepRap). It is finally complete and printing some excellent parts. Yes, I plan to eventually print an AR15 lower receiver with it.

Also, life sucks when you can't go to the shooting range. I miss it dearly and am itching to go shoot stuff! This is partly why I haven't been logging in here, because you guys make me want to go shooting. Started grad school on Monday in addition to work. Have a supermega cold and I was the last in my house to get it, so baby is feeling better, wife is feeling better but I feel like crap. Uh, I think that's about it for now.

Oh yea, and it apparently snows more in NM than it does in VA. Which really baffles me and is kinda disappointing.

Did I read that right. You used a printer to print a printer? If so then I wish to commission you to print me a printer using your printer printed from a printer.

You still have to buy all of the electronics, motors and then assemble it all together. But I dare say it was more fun to assemble than building an AR15 from scratch (including upper). With that said, as an engineer I have already found numerous flaws in the design I made and am designing my own printer from scratch now that I know the in's and out's of them. The design I'm making will also be easy to quickly disassemble and move around (such as take on a plane down to Chile with me...).

Any recommendations for someone to order me a rifle on the Aurora side of town?

Some members here have used him with good results.

I thought it was thirsty Thursday

That's tonight

sweet baby jesus. So I could buy a 3d printer for roughly the price of an AR. I like it, and need one

The problem comes when your printer decides you are the problem and sucks you out into space or puts you in a tube and uses you as a battery. (I might have got that from a movie though)

I actually built a CNC wood mill once. (Down in Las Cruces actually) My friend handled all the electronics and computer stuff. I built the table, frame and rail system for it. It's been going strong for many years at his wood shop.

Were the flaws you found in the mechanical side or electronic/comp side?

Whores!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!

You back from never never land ?

[BuffCyclist]

Entirely mechanical.

For instance, they put the extruder/extruder-motor/extruder-nozzle on the end of essentially a diving board. So it flexes like crazy and precision is affected. They used bronze bushings on steel shafting, which is good when things are cut with a CNC and the holes are truly concentric. But when the bushing holders came out of the printer, it took me 2 days to get them aligned so the mounts (with 2 bushings per side mounted on) to move freely along the shaft (ie fall down a vertical shaft when held at top and let go). The linear guide rails and carriages they used were plastic, so I can't clamp the extruder carriage down enough to ensure it won't move when the x-axis motor belt tugs on it in either direction. The z-axis motor mounts are not gusseted, so they flex under the weight of the motors/shafting. The flexible shaft coupling for the z-axis introduce a spring like effect since the bottom of the leadscrews are not supported. So the distance between the threaded nut and the motor could change depending on how fast the motor changes direction. The glass build plate is overconstrained (by a clamp) that doesn't allow it to expand/contract as it heats/cools. This introduces a rise/fall in the center of the plate when the heater turns on/off to maintain a set temperature (70degC). Uh... I'm sure there are a dozen more but can't think of them at the moment.
