XRobots – 3D Printing on Battery Power, with a RepRap Lulzbot & Car Battery! Updated on December 2, 2014 By Windows Guy 25 Comments I need to do a 3D Printing demo next month at an exhibition, but there’s no power!. How long can I run from batteries?

Do you think the printer control electronics has a regulator inbuilt? Were you at all concerned with the battery voltage being a little high? I’d be interested to see what the current drain was with the HBP. I’d also be interested in how the power requirements of your other printer compare. WATCHMAN1611 December 2, 2014 You could even afford to put the heated bed back on. Jason Kay December 2, 2014 wow that takes a lot less power than i expected. Just one question, if the print is interrupted such as if the power ran out half way, can you continue from where you left off and if so are there any problems in the final print such as the layers not sticking together from where you left off or something. fragmen52_ December 2, 2014 you should see if you can set up a circuit to switch to battery if the power goes out InsaneMusic576 December 2, 2014 When about is the next Hulkbuster video and Back to the Furture cosplay vlog? François Bada December 2, 2014 This is out of topic, but wich hotend do you use for your Taz printer and are you happy with it? Also for the bed using PLA, I use kapton tape wich works well most of the time. James Bruton December 2, 2014 Can I run a 3D printer for two days on batteries?! Danon A December 2, 2014 Just keep in mind, that if you over drain the car battery too to much it may loose it’s ability to be recharged. You might want to do some research & learn specifically what you can & can’t get away with, with doing something like this. You don’t want to use the battery all day Saturday, & then find out it wont take a charge for Sunday because you over discharged it. Also some car chargers may not charge fast enough, you may want to make sure that that battery charger is capable of recharging a car battery from almost dead to a full charge in the amount of time that your going to be able to be in your hotel room over night. side thought also, you might be able to go to a car junkyard (scrapyard) to pick up a used car battery (or two) for really cheap. Some junk yards will purposely pull the car batteries out of the cars & sell them for say, $10-$20. (American) Love the vids & builds, keep up the great work! Jurassic Xenomorph December 2, 2014 Finish the Xenomorph! matthew robins December 2, 2014 Are u still making your lightsaber Richard Champagne December 2, 2014 Please remember that car batteries vent hydrogen gas when charging. Charging it in your hotel room overnight may not be a good idea. rayvr December 2, 2014 which is the best for printing in your opinion abs or pla? how would i chemically bond pla like u do with ur abs/acetone mixes? Zplizor December 3, 2014 As far as I know, the 24V printer can also run somewhat on 12V, the steppers will maybe act up.. but the rest should run “okay” catseye10000 December 3, 2014 wow in america we don’t have to pay for power separatly Alec Unver December 3, 2014 Why dont you print in PLA more often? Are there disadvantages to it compaired to ABS? Dylan Bezzina December 3, 2014 First Jay May December 3, 2014 A deepcycle battery would be good to use for this application.. At the hospital I work at they use these sort of batteries for the workstations that are on carts. MrDuelMind December 3, 2014 “I haven’t seen that meter go over 3.6” *It immediately starts raising up and jumps to 3.7* Just to spite you! Evan Emanuel December 3, 2014 Very good method man well done on it. Mark Ifi December 3, 2014 Outsmarting the collectormania organisers? Well done. MrNeversleeps December 3, 2014 with a more complex shape is the drain on the battery more? Would it better to do shapes with a smooth draw path and no infill so the motors are not going back and forth constantly shifting directions. I know nothing about current draw and battery life so not sure if the motors moving like that even matters. crazietj December 3, 2014 James, you might want to think about a gel cell deep cycle battery. I’m from the US and not sure what battery you are using, but with a regular car battery if it gets down below a certain amp, the battery can become damaged, leak or not take a proper charge. With a gel cell battery it’s more for use in conditions where it can take a lot of movement and not cause any damage to the cells. They can even be turned upside down and work perfectly. ghassan mouhaidly December 3, 2014 awesome uploading rate james, keep it up :) Cyclone Ninja December 3, 2014 hey man i know you are busy with the hulk buster suit and other things but would you be able to do a full in depth video teaching us how to make the ironman suit from foam, because i would love to make it but I’m not very good unless i have got instructions. TheKnightsShield December 3, 2014 Great job, James!! Next thing you know, you’ll be going all “green” and start powering your 3D printers with batteries and solar panels more often. You never know, if we get a great hot and sunny summer one year, you’ll be able to sit outside printing all day without using mains power or batteries, unless solar gives insufficient power of course. Now there’s something to think about: solar projects and 3D printing. ;) Comments are closed.
