I'm building a giant 3D printer from scratch, the printer will have a print volume of 1000x1000x1420 mm. Everything you see in the video has been designed and 3D printed by me and the files will be available on my website www.ivanmiranda.com when the project is finished.
I'll be using a Slice Engineering magnum plus hotend and It is controlled by a Duet3 MBHC which is a fantastic controller, check it out!:
www.duet3d.com/products
In this episode I install 4 - 1Kw heaters on a 3mm aluminium plate. The heaters are individually controlled by the Duet3 through 4 SSR and each heated bed has an independent thermal fuse just in case things go haywire.
On top I used a regular piece of 5mm glass. That will be more than enough for PLA or similar plastics.

Have you considered a counter weight system for the bed? 80% of the bed weight should save those resin gears while still maintaining downward pressure on the belts. Then you only have to worry about the weight of the print. Can't wait to see what you print on this monster.

You can get solid state safety relays which fail safe. With that much power I'd definitely consider using those instead. The thermal fuse is probably worthwhile as well, but if one of those blows you'll have to pull the whole heater pad and insulation off to fix it.

SSRs are not truly fail safe in any form. I deal with them professionally, and no compaince body on earth will approve them in a fail safe capacity. The only legally approved safety systems for SSRs are high limit cutoffs (capillary tube or thermostat style) or an approved control system (similar to a medically approved software system, or an approved mechanical control) with a second element like a mechanical relay.

@@florianhinsch4912 You're missing the point. Let's say you are running them at 75%, which is close to the 80% in the video. If you PWM them all at the same time, you are pulling the full current for 75% of the time, then no current for 25% of the time. If you stagger them instead, you are still pulling the same average power, and so producing the same heat, but now you are pulling no more than 3/4 of the full current. Meaning that you get the same heating in both cases, but in one case you can easily blow the breaker, but in the other case you never do.

This is generally discouraged because a thermal fuse is meant to be a last defense against a printer failing for safety issues. A self-resetting switch will cycle back on after a cooldown may occur, but without the issue being resolved. One possible scenario is the bed overheats, the switch trips, but the adhesive of the bed is now weakend, and the heater mat seperates. Now, with the switch restting, the heater mat reheats, but is no longer attached to the bed, and is a significant fire hazard. It's a common question, someone else explained that line of reasoning to me as well.

Maybe this is a situation where instead of using the cheap Chinese SSRs that fail closed, you should use one with built-in protection. Also not a big fan of the in-line rectifier diodes under heat shrink. They could get quite hot. And I'd generally keep to the European color coding for mains cabling. Particularly for PE, it is compulsory. Colors are blue for neutral, brown, black and grey for live, and green-yellow for PE. And I personally feel like the printer should have it's own GFCI. For PE you should use a multimeter, and check that resistance between metal parts and the PE in the power cord is always well below one Ohm. I would also wire the heating in a way that it is failsafe. So even when the control board gets stuck with the PWM, or an SSR fails closed, the bed should never reach destructive temperatures (or blow fuses). Otherwise I wouldn't let it print unattended.
@ivanmirandawastaken
@ivanmirandawastaken Жыл бұрын
I agree basically with all that you said. I didn't have the proper wiring at hand at the moment so I went with what was going to work but it will be changed before putting the machine into production but not because color coding (which is important, I'm not dismissing that) but because the gauge is the incorrect one in every single cable in there. It will barely work for testing but it doesn't have the safety margin required. This is a machine that I'm designing and building along the way so mistakes and improvisation are a part of the process and once the video is uploaded a source of knowledge as I also learn from the comments 👊

@@ivanmirandawastaken My biggest fear here is that the max power is well above the power required to sustain temperature. If the control board and thermal fuse fails, and the heating keeps going, it will eventually heat up the metal frame to a point that your 3D printed parts will melt. So the quality of the thermal fuse is really important, and I'd test that behavior. I personally would try if wiring two heating mats in series gives you already enough power for sustained printing. Or even better, use heating mats that have PTC built-in. Although not sure if they exist in the required temperature range. Water beds use them for example, as overheating would be quite catastrophic.

One thing to consider would be a layer of insulation on top of the bed. You could cut it anyway you want.

Plug 2 heaters in one outlet and 2 in a separate fused outlet and you shouldn't have any issues. You will probably need at least one more anyway for the extrusion heater. I would look around the house and map out outlets and which fuses they are on so you can divide up the power properly. Either that or install some dedicated larger current separate circuit breakers and run appropriately large wires.

It looks like you could have used your 3 phase supply for the heaters, just wire them up as single phase heaters and spread them across the different phases. You could for example have: L1 - 2x bed heaters L2 - 1x bed heater + motors L3 = 1x bed heater + hot end heater I wouldn't have soldered the heater wires together given their ratings - I'd have used a butt-crimp for the wire-to-wire joints and ring-crimps for the wire-to-SSR joints. I'm not convinced that the quadrant system will work properly as the aluminium plate will act as a heat spreader. I think it would have been more effective to have four separate aluminium plates with a small gap between them.

Ive seen many electric car chargers (and forklift chargers in industrial enviroments) where the whole socket burned out and nearly set the building on fire. would suggest the blue CEE 16A 1 Phase for such applications. Those also have the benefit, that you always have the same polarity (N+L) on your wiring.

For initial heating, what about heating each quadrant to a temp over 60, say 65-70, then switch to another quadrant, and maintain the 60 as the other warms up, pausing the warming only long enough to get the maintenance temp. Or, cycle the warming sections, maybe 2 at a time, might take a bit longer, but, should allow for the draw needed, also, gives time for heat soak.

Re: Thermal Fuses. 1. Better to crimp them rather than solder, probably for obvious reasons. 2. For this application, a better solution probably would be a surface mount resettable thermal switch. Similar to what is used on say a tea kettle or electric griddle. You can get them in lower ratings and they use spade connectors so no soldering to them is required. And they can be screwed to the bottom of your aluminum build plate with a small dab of thermal paste.

Disregard: refreshed the page and now see that someone already mentioned this. Just a note about the power usage: you may have more breathing room than you think. Your original design with the 1/2 wave rectifier would have effectively been a 50% duty cycle for each heater, so if you did your original math right you might be able to reduce the PWM cycle even further and still hit the desired performance levels. Also, if you have the ability to set the PWM timings on the relays separately, you could have them running at 50% duty cycle and implement your 1/2 wave by setting the PWM timings on two heaters to be offset by a cycle. (so that two heaters are on and two are off at any given moment.)

Is there any chance that the glass part of the bed could crack/break/shatter when only using 1 heating pad because of the temperature difference with the rest of the glass?

There is a type of thermal switch that doesn't kill itself when tripped, and close when they cool off - some are used in ovens Fischer&Pykel use 190C tl-60 switches in Elba ovens good for 3.6kW.

you should limit the max power of the mates in either way. you dont want your buildplate to heat up that fast. even on smaller 300/400/500mm printers the max power is limited to 60% to give the buildplate time to expand and soak in the heat.

heating only 1/4 of the heated bed, wouldnt that produce problems? it will warp the frame and might stress the glass...

Best to combine higher power wires using wago connectors or somesuch instead of soldering.

for the resin gears just mix a small amount of flexible resin with your normal resin to make it bit less brittle

A more straightforward way to split the power among two heaters is to wire them in series.

will the insulation not compress under the weight of your prints and ruin your print height/levelling?

Hi Ivan, quite impressed with your work. Just a thought for the bed heating, cut a removable insulation pad for the top too so you can heat that massive area faster with less power. I'm not familiar with 3d printing so I don't know if that's running throughout the build(i hope not) but if you're running that in a room, do your best to recapture the heat, that could be a bonkers amount of money to run.

Typically you have to run the heated bed for the duration of the print, or else the glass contracting is liable to cause parts to detach.

Wait. How is the bed leveled? And how it keeps level while printing? The insulation foam should compress adding weight on it while printing.

most likely he will use a probe and bed mesh to level the bed also each corner of the bed has its own stepper to compensate
