After having a few failures over the past few months, i’ve tried a number of things to increase the print success rate.
The biggest improvement came from temporarily moving the printers out of the cold conservatory and into the much warmer living room.
That’s a bad thing to do on a full time basis as resin fumes ARE toxic .
There’s a whole slew of ways of heating up the printer. People have heated their rooms (expensive). Put the resin printer on a heated printer bed! (genius, and works). They’ve also cobbled together a bunch ‘o bits and made a heater. Probably the most elegant one i’ve seen is by Elegoo!
So, what does a person do when there’s pretty much a slew of commercially available suitable heaters for a 3D printer………
Yep, you go and roll your own!
I worry that the commercial ones may be too powerful I only need to raise the temperature around 10-15 degrees above ambient. Having seen friends use 50watt lamps in vivariums of much larger volume than my printers, I’ve figured a 50 Watt dedicated heater device should be more than enough….
I’m going with a https://hobbycomponents.com/sensors/684-w1209-temperature-control-switch W1209 Temperature control device and sensor
(thankyou to https://www.thingiverse.com/thing:3442165 for the inspiration for the product and also this Hackaday Article
a 50 Watt PTC Heater 12V DC https://www.amazon.co.uk/gp/product/B07SC15TK7/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
(thankyou to the Elegoo heater thingy for this decision)
and a 60mm Fan https://www.amazon.co.uk/gp/product/B07HCGZ5FZ/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Thank ME for this one – I purchased 5 off 80mm Artic F8 case fans back in March last year for an absolute steal. With the intention of upgrading cooling on the Wanhao D9 and in anticipation of designing a small heater for the resin printers. I can’t find them, so, this pair was about the best deal I could find for quick delivery
This lot cost me about £20 in total – Not bad considering it’ll be twice as ugly as the £10 commercial units, which, at £10 will be delivered in March, which co-incidentally is about the same date that i’ll likley finish assembling this monstosity!, D’oh!
Now, All I need to do is create some sort of 3D printed enclosure to house ’em all, figure out how to route cables and voila, i’ll have a nice ‘thingy’
Note, this lot can be gotten for easily around a tenner total, if your patient. However, It’s cold NOW, so i can’t wait a few months for delivery (when, in the UK it’ll still be cold, just a bit less cold)
