Stories from my 3D Journey with Blender, Solidworks and 3d printer
Jake’s Workshop converts his 3D printer (A Prusa I3) into a laser cutter…well…laser engraver unless you want the most expensive pair of scissors ever invented. It uses a 500w laser for AliExpress. Laser, driver and safety googles are currently selling for $34.
You can save yourself some plastic if you know the theory behind the I-Beam and the Real Engineering channel on YouTube explains why I beams are shaped like they are. It explains the second moment of area (sometimes refered to as the moment area of inertia).
Do you have a part that you are thinking about printing, but your are worried about the strength? MatterHackers has done some unscientific comparitive testing for you. You don’t need to be an engineer to understand the test. They printed some parts and tried to break them. Check it out.
