3D Printer for 75 bucks. (Page 7/10)

Ohhh...I LIKE.

I need to grab some "fun filament". 3D max has a 10 for $200 deal on PLA+ (which is cheap for Canada, I usually pay around $25-40 a roll) so I might stock up. Went a little overboard with the bikes this summer and all the mad-money has been going in that direction.

I'm ok paying around $25 a spool for the kind of prints I'm doing. PLA+ is typically the recommended material for the kind of print above. In Texas it's a little comical, I've got about 500 round through the orange one, but a few hours in a parked car could completely ruin it.

I did a stepper bracket in PLA+ a while back for the E3. It lasted about 6 weeks until the sag was bad enough I couldn't use it anymore. It was part of a mod to get rid of the eccentrics on the Y bar.

Here's another I did, the stock was done in 6 pieces.
The barrel is off the shelf but like the orange one(not the easiest to see in the picture but it's not an off the shelf part), I'm thinking about making one for it. The printed barrels consist of a rifled steel liner, a carbon fiber tube over the liner printed ends and a larger carbon fiber tube over all that.




Definitely doesn't get as hot as an E3. Really some easier to obtain and use high temp and impact resistant filaments would be a game changer for this type of stuff. It's a little amazing it's gone as far as it is considering the plastics we are using.

I havent had the nerve to try anything under pressure or tension with the 2A stuff. Just stocks, grips, mounts ect. ONE of these days I'd like to do an Baraba with a folding stock. Maybe this winter.

Biggest issue with crossbow-type stuff is the string catch in the trigger mechanism doesn't last for **** . Might try making that out of CF filament next time.

For the longest time, I had no interest in 2a stuff, especially when it was mostly just the AR15 lower people were obsessed with and it wasn't like you were saving much by printing that, or ending up with a great rifle, but that has changed as they've come up with some very strong AR lower designs and are now printing much more of the rifle. I still don't care for the AR design printed/cheap or not, but I may put up with all the things I dislike about the AR platform for an AR10 built off a printed Hoffman tactical lower.

I have printed some useful stuff and some silly stuff.

I made some feet for my backup drive.



And some gris gris to keep the bugs away from my computer.

Very cool!

I just ordered one. I've been wanting to try 3D printing, but just didn't want to spend the money. The ebay link you gave had a price of $80, but you could also make an offer, so I offered $70 and they accepted. Waiting now for it to arrive. Do you still recommend ordering the magnetic bed sheets, as this seems to come with that.

Speaking as a complete amature/newby, I have had no problem with the parts sticking when they are supposed to stick and releasing when they are done, using only the supplied bed.

Also, I have bought filament from two different brands chosen for their low price with good results.

So far, it has been a relatively trouble free experience once I got past the initial problems that I mentioned above. You just upload a file and tell it to go to work.
