Why We 3D Printed Copters – Flexbot
Today we have a great guest post from the team over at Flexbot.cc, who have some great info about their experience with 3D printed copters. Enjoy! Hi Guys, Alyssa here from Flexbot！ We’re really excited to share a little about what we’ve been working on at FlexBot, and how we’re using 3D printing to make it all possible! For a quick backstory about what we do, check out our Kickstarter video from October 2013, when we successfully raised $563,721 to fund our awesome little drone.
- First and foremost, keep the body design light. There are limited motors in both the quadcopter and hexacopter, which mean the lifting force is also limited. A assembled FlexBot quadcopter (with motors and battery) is 40g and the hexacopter is nearly 46g. To make sure your FlexBot hexacopter can carry a camera, the frame should be about 10g.
- Second, to make it easy to print the design successfully, make sure the bottom side is perfectly flat. This makes it easier for your printer to be successful, and provides a solid base for the frame.
- Third, avoiding holes and dangling parts. Those parts will be difficult to 3D print on a home printer. The dangling parts need supports, meaning you have to do more design work and you’ll use more material, costing you more money.
- Last but not least, try not to make the parts too thin. I know you want to make it nice and light, but parts that are thinner than 1mm generally don’t print successfully.
We put three words on website that are important to us; “design, make and share”. People love to share, and so do we. As a result, you can find all of our source code on github, and the files for a couple of our 3D printable frames right here on Pinshape. We can’t wait to see all the variations our enthusiastic user community comes up with, and if you’d like to join them, check out our website and order your very own drone today!
