Theoretically, a 3D scanners and 3D printing devices are a thoughtl match. We can’t be the only ones in love with the thought that you can only scan a broken component and easily 3D print a new one without having to invest the time in extensive CAD create. So why, you can ask, aren’t we seeing 3D scanners in every manufacturerspace in the world? But it is finally taking place, 3D scanners aren’t coming down in price only as rapidly as 3D scanners and it can many likely take a few additional years preceding a great high end version is on the market to the average hobbyist. So why not create your own? That is, fundamentally, what Alex of YouTube channel SuperMakeSomething has done: a DIY scanner packed with 3D printed components and off-the-shelf electronics.
SuperMakeSomething, of course, is one of the many enjoyable building channels on YouTube, and are always great for a few inspiration for your future project. They have in addition only commenceed a new SuperMakeSomething website. Alex is especially great at building really complicated produces appear super effortless, that is in addition the case for this DIY 3D scanner, as you can see at a lower place.

If you can’t avoid the temptation, you will be pleased to understand it fundamentally consists of nothing additional than a few off-the-shelf electronic components, with an infrared sensor acting as the main scanner. Aside of the sensor, it in addition contains two NEMA 17stepper motors, a few motor plates, a threaded rod, two guideshafts, an IR sensor, and a few electronics: an Arduino Pro Micro, a power connector, a hustle button, an infrared sensor, an SD card, and two stepper driver boards. Everything is connected with male and female header pins and screw terminals.
You can in addition require to create a custom PCB, for that the produces are on the market here. Alex utilized the great Eagle Freeware CAD software to create it, maybe the easiest way to create a PCB at home. Whilst that is really a challenge if you’ve nat any time created it preceding, the web is filled with useful tutorials that can get you through that system. Much easyr, yet, is to only order the produces through developer Osh Park, where Alex uploaded the files. You can order them here – many of the complex work is may aleager done for you!


The same goes for 3D printing: Alex has createed all components in SolidWorks CAD software, and has created them all on the market on Thingiverse here. There are only sactually components (the mounting plate requires to be done twice) that require to be 3D printed, and should be compatible with many PC FDM 3D printing devices out there – Alex utilized his MakerBot 3D printing device. Total print time was of 10 hours.
Really the only challenge for the beginning manufacturer is building the electronics and programming the Arduino, but here it’s largely a matter of next Alex’s great steps. He has actually provided the Arduino code, meaning you will only have to download the code and follow his tips. The code is fully capable of slowly turning the turntable and scanning the visible side of the object.
Choosing zip ties and screws, the whole setup can be easily assembled – a piece of cake for anyone who’s at any time worked on slightly additional complicated produces preceding. Simply follow Alex’s steps, and almany nothing can go wrong. Just manufacture certain all the electronics are placed and installed correctly, but actually this is created easyr with a few instructions printed on the front of the board. Alex manufactures it all appear so easy.


To use this DIY 3D scanner, only use double-sized tape to stick the object in question to the middle of the turntable and plug in the power source. “The time it takes to scan an object depends on the parameters in the Arduino code, such as the desired angular resolution, number of scan samples per reading and the amount of time to pause between every turn of the turntable,” he explains. In the clip at a lower place, a scan was accomplished in of forty minutes – lightning speed if you are utilized to a 3D printing device.
The files, finally, can be discovered on the SD card and can be accessed via Matlab. The systeming code for Matlab is in addition pre-written, and can be downloaded here. Alex’s code can encertain all data is converted to a conveniently 3D printable STL file, so you are eager to go on building as rapidly as possible. To be certain, the resolution of the final scan is not rad – the noise and resolution of the sensor greatly limits the scanning ability, while a lot of filtering is required in Matlab to end up with a smooth 3D printable object. But this can be improved (for instance with a laser range finder and optimizing settings), it is yet without a doubt the many low-priced and coolest DIY 3D scanner we’ve at any time seen – unquestionably worth checking out.
