heated enclosure

[lean storm]

I'm planning to build a heated enclosure around my sovol sv06+ with foam insulation panels around a 3d printed frame. I'm going to put the electronics box outside of the enclosure and have extra cooling for the stepper motor. What other things should I be worried about?

AI Help

When building a heated enclosure for your 3D printer, there are a few other things you should consider:

1. Fire safety: Make sure your enclosure materials are fire-resistant, especially if you're using foam insulation panels. It's crucial to prevent any potential fire hazards.

2. Ventilation: While it's great to have a heated enclosure, it's equally important to ensure proper ventilation to prevent overheating. Consider adding fans or vents to regulate the temperature and maintain a suitable environment for your printer.

3. Heat distribution: Make sure the heat generated inside the enclosure is evenly distributed throughout the printing area. Uneven heating can affect the print quality and cause warping or other issues.

4. Ambient temperature control: Ensure that the ambient temperature surrounding the printer is within a suitable range. Extreme temperatures can interfere with the printer's performance, so it's important to maintain a stable environment.

5. Electronics cooling:...

I'll also be using this to heat the chamber

Connected to an external MOSFET, controlled by a fan pwm and directly into the power supply

I'm planning to 3d print a frame out of PETG and put fire resistant insulation panels around the sides and top

And an acrylic door in front

Sounds good, if you want to be real safe add some fire protection stuff (smoke/flame alarm, automatic extinguisher). I don't know if the 3d printed frame is a good idea though. Maybe simple wood beams and panels or extrusion might be simpler and doesn't get soft when warm. As the AI said, put some fans into the enclosure to regulate heat and move the heat around slowly. While you are at it, think about air filtration, maybe look into the "nevermore" system.

The 3d printed frame is the cheapest option out there. Petg should be plenty heat resistant for what I'm using it for. I'll be using recirculation filter

[south juniper]

Just looked it up, had the wrong number in my mind. Petg should be fine plenty. If you are fancy you could get self extinguishing petg and one of these https://blazecut.com/t-series/

I've seen people running arduino controlled diy CO2 extinguishing systems using paintball tanks or sodawater(?) cartridges. Maybe for a later upgrade.

Also, when was the last 3d printer fire from one of the newer machines. They seem mostly safe now?

[lean storm]

I'm modding the shit out of mine and turning it into an IDEX with my own toolhead and firmware

There's a good chance that it catches on fire 😭

[south juniper]

Ah i recall

[lean storm]

The board that I'm using has a helluva lot of thermistor ports tho

So I'll be having a bunch of those populate the chamber with thermal runaway emergency shutdown

Got this beast for 46 with 8 tmc2209 drivers

[south juniper]

Good idea, definitely. Running klipper then?

[lean storm]

Oh yeah

Absolutely

[south juniper]

😁 Will be awaiting your results

How come you're adding a heater? Just curious

[lean storm]

ABS

I'm also planning to build a PEEK printer later so this is good practice

But that's for my university project

[empty cliff]

I'm building one as well, I was just going to rely on the heat the printer gives off the warm the enclosure up

The only thing I would be concerned with is making sure your foam insulation is fire proof and isn't going to be dropping any little bits on your machine.

I'm not getting as fancy as you, I'm using 3mm plexiglass and a house thermostat to regulate heat with fans

Oh that's pretty cool

[lean storm]

For the peek printer I'm planning to use this style of motion system

With the steppers safely out of the way

And with oven heating coils heating from above

It's probably only gonna be 120x120

The real issue is going to be having it maintain a 140c enclosure temp to make sure that the PEEK is in it's semi-crystalline phase

[lean storm]

I'm using the heater bc I got inspired by the qidi X+3 and since my motherboard has so many damn ports anyway might as well

[empty cliff]

"I paid for the whole motherboard I'm gonna use the whole motherboard"

[lean storm]

Also I'm enclosing an entire bedslinger so it's gonna take a while for the bed to heat the enclosure

[lean storm]

Ur goddamn right

[empty cliff]

Have you found a thermostat that will be able to maintain your 140°?

[lean storm]

I'm planning to do it myself

By building an oven ish

I'll probably end up using some oven parts

[empty cliff]

Sweet. If you go that route you may want to consider a high limit switch to keep your temps from going too high

[lean storm]

I'm gonna have the temperature controlled by PID

This is what I'm planning to do for my senior design project in a year so I'm just brainstorming rn

[empty cliff]

I'd probably still put one in as a backup failsafe myself just to be safe, I work on heating equipment and installations and every one of them has a high limit, they usually only trigger when something has gone really wrong inside

[lean storm]

Oh yeah it'll definitely have thermal runaway protection

The real issue will probably test printing the PEEK

So damn expensive 😭

It's for a satellite so 🤷

[empty cliff]

Those are going to be some expensive benchys

[lean storm]

If I can get it working then it'll be helluva lot cheaper than the alternatives

[lean storm]

Pretty much a dollar/gram

[empty cliff]

Yikes haha

That's going to hurt the Wallet

[lean storm]

Time to find a sponsor
