3D Printable Thermal Enclosure For 3D Printer

Well, OK, not the whole enclosure, just the parts that hold it together.

MegaMax can print big stuff but he’s had problems with large prints delaminating.  The answer seems to be enclosing the printer to keep the prints warm while printing.  I designed this box and 3D printable parts to hold it together so that I can take the box apart easily to work on MegaMax or move him to other locations and put it back together when I’m done.  The box is 38″ D x 28″ H x 32″ W.

The box is made of 1″ PIR foam with corners suitably notched to accommodate the printed parts.  MegaMax has a 450 Watt heater in the printbed so the box gets super-toasty inside.  I suspect it gets a little too toasty but haven’t made any measurements yet.  I’ll soon be moving the electronics out of the box.  I didn’t do anything to seal the seams in the box because it doesn’t seem to be necessary.  I did tape the edges of some of the foam boards with clear packing tape to prevent damage.

We’ve got a Laser Cutter! We can cut things… like boxes. So head on over to BoxMaker and make a box!

As far as materials, that’s a little trickier. I tried wood, but currently the laser cutter can’t handle cutting your standard 1/4″ plywood. (Update: 3mm Baltic Birch plywood works great though!) Here you can see the results of me trying.


No matter… I moved on to acrylic, since we’ve got a lot of acrylic scrap to play with…


That worked much better! Hopefully once we do some laser maintenance (cleaning and what not) it might be able to cut wood. Of course you could always use BoxMaker to create your box and cut it on the CNC Router instead.

So here’s my laser-cut acrylic box. Notice anything? The tabs are way too big! In my frustration of not being able to cut wood, I switched to the acrylic, but didn’t measure the thickness and create a new file, and since it was not as thick as the wood, I got the tabs all wrong.


Still, BoxMaker is an awesome tool, and I look forward to getting the cutting part right next time.
