Small pastime airplane and lightweight plastic portions cross hand in hand, and a three-D printing pen makes light-weight plastic issues with out the overhead of CAD paintings and operating a three-D printer. So may just a three-D pen create helpful plastic bits for small quadcopters? [Michael Niggel] made up our minds to determine through. He most commonly came upon that the created items may just in a well mannered way be mentioned to appear to be they have been sketched through a baby, however that’s no longer all he realized.
He discovered that usually developing an object was once more difficult than the selling fabrics implied. As quickly because the filament exits the pen’s nozzle, the skinny little molten line of plastic cools all of a sudden and does two issues: it tends to curve, and loses its want to keep on with issues. [Michael] discovered the entire affair labored a lot much less like ‘drawing in skinny air’ and slightly extra like piping frosting, or caulking.
An nearly practical micro quad body. The palms aren’t inflexible sufficient to carry the motors vertical when beneath energy.
Nevertheless, [Michael] sought to find whether or not a three-D pen may well be used to make fast and grimy portions of any use. He created two antenna brackets and one micro quad body. All three are chaotic messes, however one antenna bracket was once completely serviceable. The three-D pen was once certainly ready to create a strangely-shaped section that will had been a nightmare to CAD up. The different antenna section labored, however didn’t do the rest a zipper tie wouldn’t have achieved higher. The speedy cooling of the plastic from the three-D pen has a bonus: extrusions don’t “suspend” like a glob of sizzling glue does earlier than it hardens.
By now, [Michael] agreed that one of the simplest ways to create a plastic a part of any complexity in any respect looked to be to attract sections flat, construct them up in layers, then use the pen to weld the items in combination and upload bulk. The micro quad body he made on this method doesn’t glance any nicer than the opposite makes an attempt, but it surely did dangle the portions appropriately. Sadly, it will no longer fly. Once the motors powered up, the palms would twist and the flight controller was once not able to catch up on motors that wouldn’t keep directly. This may just most definitely be triumph over, however whilst the outcome was once grimy it surely wasn’t fast. The three-D pen’s area of interest turns out limited to easy, unstressed portions that aren’t accepted to gaze up themselves in a reflect.
