With respect... nope, ALL 3d printers are extremely dangerous to leave unattended.  Anything with a heat source shouldn't be left on while you are gone because heat can lead to fire... that's just common sense.  You don't leave the oven on while you are away do you?  How about your soldering iron?  Yeah it's that dumb to just walk away from something that is hot enough to melt plastic. Thermal runaway protection is not 100 percent reliable and if you are relying on it you are literally playing with fire as they only monitor the internal temps of the hotend and heatbed and now any fires on the bed itself from heating contaminated plastic or the psu.

I do agree that anything hitting 400 degrees should be watched, I guess I lost concern after 3 years of printing with no issues.
I should probably start looking at a all metal container or something, as always something bad is bound to happen.

3d printer is the one thing people are surprised I don't have yet.
but figuring out which one to get  :dizzy:

I do like the looks of this one and it's features.
https://www.amazon.com/Geeetech-Rostock-Triple-color-Filament-Diameter/dp/B072PZKSVT/ref=sr_1_8?ie=UTF8&qid=1509125450&sr=8-8&keywords=geeetech+rostock

I want a kit so I can build it and it's got color mixing!
which i'm sure will require fiddling to work right but i like tinkering.

That's supposed to be a good printer but keep in mind you are literally paying an extra 250 bucks just to print in three colors.  You might want to buy one that is mono color that can be upgraded at a later date.  I only say that because 3d printing isn't for everyone... it's quite tedious to make what you want and depending upon your time schedule you might discover that it isn't for you.

that thought had occurred to me also.
I may end up just printing a bunch of models I found online then letting it collect dust.
Or may learn to actually create something new on it or copy the stupid little plastic parts that occasionally break on my 20yr old car cause 20yr old interior replacement parts off a parts car are still 20yrs old. :)

I definitely want a kit so i can put it together.
I know the best way for me to learn how one actually operates is to assemble as much of it myself.

this is probably what i'm looking for then.
https://www.amazon.com/ALUNAR-Desktop-Printer-Accuracy-Assembly/dp/B018XJ3E02?tag=affordable3dprinters-20

kit form and inexpensive.
still will have to wait until tax return season.

I've seen some prints with the wood filaments.  Yes, it takes stain pretty well, though it's recommended that you scuff it up a little before hand.

Ive, made a few boxes with the wood filament, smells like actual burning wood when you print. Id like to do some models, the Groot Titch shared came out really good.

I had to buy an upgraded extruder in order to use Ninja Flex, the slightest gap would cause the filament to bend.
If you do get metal, carbon fiber or any abrasive filament remember to stock on on nozzles, its like running sandpaper filament through.

Actually they are 2, I wanted the text to print out clear so I did a small strip printed facing up with the text on it, made painting easier also. Then just used some CA glue.

I've got to do a set once my printer is back up.  I'm thinking of doing stands or hooks for some of the gamepads as well.  N64 controllers and Xbox Dukes in particular are a giant pain to display because they take up so much room.

I considerd doing a controller display but i have way too many consoles and not a lot of room

I've got that back wall on the WON cabinet.  I haven't decided yet if I'm gonna display carts or controllers.  The Nintendo consoles have more carts and the sega ones more controllers.

Was super easy to do, too.  Heated up pieces of paperclips with a candle and jammed them into the bottom of the teeth and then stick the teeth in pumpkin.

Printed the teeth with a brim so they would stick to the bed.

Cool beans man. 

My 30 amp power supply came in yesterday and I went ahead and printed the "d" and "o" even though the mofset hadn't arrived yet.  Considering the low cost, it might be a worthwhile upgrade to the anet/prusa printers.  I had it running about 3 hours non-stop and the power supply didn't even get warm to the touch.  I'm sure the fan helped, but regardless the whole unit just feels a bit safer now.

Sure if you can sleep at night with all that blood on your hands.  When the NRA even agrees that a gun product should be outlawed it's pretty bad.

I'm an enthusiast, and the first thing that went through my mind when I saw those a few years back, was that's the next thing to be banned.  That said, for all the time they've been available, this is the first and only time they have been used for something like this.  It's also important to note that they aren't necessary to make a weapon behave like this...it just facilitates it.

Cool to see more folks playing with 3D printers.  I'm guessing you guys are starting to see now why very few make large 3D printed parts to sell.  Unless they are very rare and often sought after items, the design time, print time, maintenance and materials usually makes it not worth the effort, or the final cost of the item too high to be reasonably marketable.  But they are great for tinkerers, making personal "one-offs" and prototyping for other manufacturing processes.  Not sure we'll ever see machines based on this type of technology which would be well-suited to replace the more standard methods of production.

*sigh*

I made a lengthy post in response to that, but I don't want this thread ruined so I deleted it. 

Anyway....

I agree that 3d printers will probably never replace more traditional manufacturing methods.  What I can see happening is that 3d printers eventually become so turn key that manufacturers might send you an stl to print out when you break a knob off your dryer instead of sending a replacement part.  I eventually see them installed as a vending machine in Lowes/Home Depot.... right next to the key machine.  It's good to print out a rough shape for a casting project or something like that.  I believe someone is selling a wax filament now.... that'd be great for casting jewelry and gears and stuff.

Yep, high density wax filaments have been around for a while now.  Making investments for bronze casting is why my wife wants to get a 3d printer.

So now it's even easier to bootleg Warhammer figurines?  Print it in wax, mold in silicon, and melt some pewter.

What I can see happening is that 3d printers eventually become so turn key that manufacturers might send you an stl to print out when you break a knob off your dryer instead of sending a replacement part.  I eventually see them installed as a vending machine in Lowes/Home Depot.... right next to the key machine.  It's good to print out a rough shape for a casting project or something like that.  I believe someone is selling a wax filament now.... that'd be great for casting jewelry and gears and stuff.

I tend to think that the FDM process will never really be that autonomous.  I have an expensive unit, which I use exclusively for prototyping.  It prints perfect parts, and did so straight out of the box.  But geometry plays a huge role in what needs to be done after.  Some parts pop right off the raft, and some are a nightmare to release.  Support structures can also be a major issue.  There are just too many variables, too much post-print work, and the process simply takes too long for something like a vending machine.

But for something like you mentioned at the end, absolutely!  That type of application is where these machines really shine.  I would imagine that a wax filament model would be really easy to clean up and make a very nice master for molding.

The stuff here just melts away in an oven leaving whatever you put around it after printing.
