Idea? Use an old cube shaped deep freeze (refrigerator)* with a thermostatically controlled paint stripper heat gun** blowing air in at the bottom. * Excellent thermal insulation. (Ideally with a front opening door (or a glass door***)- not a top loader) ** Thermostat mounted above the printer. *** Point of sale drinks type fridge. + Excellent noise insulation ++ Web cam inside the fridge to see what’s going on from the "design studio" in the house maybe. Aesthetically the beauty is in the eye of the beholder but in the workshop/garage no problem.

BTW, I was exaggerating about finding puddles of melted ABS parts ;) While ABS won't turn to liquid at 100C, if you pass it's glass transition temp (about 105C) it will get soft and will be much more susceptible to deformation due to printer movements. I wouldn't go above 80C just to be safe. Besides, if you can get the chamber temp up to 80C you definitely won't have any problems with ABS warping!

I think the one in my cooker oven in the kitchen is about that size.

That may turn out as a forge not a printer if the thermostat / couple were to go rogue.]]> hdp160 General Sat, 28 Sep 2013 10:48:09 -0400 https://reprap.org/forum/read.php?1,246320,248730#msg-248730 https://reprap.org/forum/read.php?1,246320,248730#msg-248730 aduy General Wed, 25 Sep 2013 21:59:20 -0400 https://reprap.org/forum/read.php?1,246320,248631#msg-248631 https://reprap.org/forum/read.php?1,246320,248631#msg-248631

The LEDs are wired with resistors in the LED strips so it's understandable that the heat produced by those resistors would contribute to the warping of the steel sheet. I image that this LED strip would draw a lot of power. How do you plan on controlling the power supplied to this LED strip?

However, wouldn't it be very inefficient to use LED strips to heat the chamber? LEDs are fairly efficient at producing light so even though they do product some heat, most of the energy they consume is converted into light energy which would be useless for your application. An alternative would be to use a Prusa PCB bed or a silicone rubber heat bed sandwiched between two aluminium plates with fans blowing over them to circulate the heat within the chamber. The advantage of this is that you could use an adjunct electronics board to easily control the chamber temperature.

My 2 cents :)

Certainly not enough to justify spending a few hundred bucks on a nice heated chamber.

And buying some dampers will do more for machine noise than a chamber - unless you're using thick acrylic or some other medium that will absorb a lot of sound. It will also likely improve print quality for most. Not a ton, but depending on your setup it could.

As for the smell, well, you got me there, but I really like the smell of ABS when it's printing. :)]]> cope413 General Mon, 23 Sep 2013 13:48:01 -0400 https://reprap.org/forum/read.php?1,246320,247916#msg-247916 https://reprap.org/forum/read.php?1,246320,247916#msg-247916
Chambers may be expensive to produce in the short-run, but if they're thermally efficient they can be very inexpensive to operate in the long-run.

I've tried the turkey bag method before with mixed results. It's why I built a heated chamber. That and you're radiating/wasting all that energy. Better to leverage that trapped heat and keep your running costs low so you can buy more filament.]]> akhlut General Mon, 23 Sep 2013 13:28:06 -0400 https://reprap.org/forum/read.php?1,246320,247903#msg-247903 https://reprap.org/forum/read.php?1,246320,247903#msg-247903
I mean, it sounds like you're going for function over form, so why not make it cheap and easy on yourself?

You can get poly tubing for a few bucks. Print a few "arms" that connect to the top of your printer that you can drape the tubing over, and voila - cheap temp controlled chamber.]]> cope413 General Mon, 23 Sep 2013 12:48:33 -0400 https://reprap.org/forum/read.php?1,246320,247825#msg-247825 https://reprap.org/forum/read.php?1,246320,247825#msg-247825
Just to be clear I think the the creamy coloured building insulation panels like Kingspan, Celotex Etc. are made of polyisocyanurate foam not polystyrene (which can be inflamable if not treated and also has a very low melting point.)

So would go for Polyisocyanurate.]]> hdp160 General Mon, 23 Sep 2013 07:21:49 -0400 https://reprap.org/forum/read.php?1,246320,247736#msg-247736 https://reprap.org/forum/read.php?1,246320,247736#msg-247736 uGen General Sun, 22 Sep 2013 20:56:15 -0400 https://reprap.org/forum/read.php?1,246320,247728#msg-247728 https://reprap.org/forum/read.php?1,246320,247728#msg-247728 miso General Sun, 22 Sep 2013 19:31:30 -0400 https://reprap.org/forum/read.php?1,246320,247598#msg-247598 https://reprap.org/forum/read.php?1,246320,247598#msg-247598

This is an idea in the earliest of stages.

But maybe an internal radiant bar heater (with thermostat obviously) to speed up the warm-up of the compartment prior to printing especially on a cold day and if the unit were in an unheated garage Etc.

I like the idea of utilising the freezer box on a fridge freezer the way you described (for both storage and feed point.)

UPDATE..

Would also eliminate the smell (except when you open the door)

But even an old freezer/refrigerator would work. Store the filament on a bar in the freezer and feed it down into the fridge via a hole drilled between the chambers.]]> akhlut General Wed, 18 Sep 2013 07:55:37 -0400 https://reprap.org/forum/read.php?1,246320,246368#msg-246368 https://reprap.org/forum/read.php?1,246320,246368#msg-246368
I was thinking of stripping out the plastic lining, replacing with plywood and using the space where the compressor lives as filament storage and location for the heater.

Fridges are "air tight" that’s why mould grows inside an unused fridge, so the magnetic door seal would probably work for a positive (internal) pressure inert gas environment.
