I love waking up with an idea, jumping into Blender or Shapr3D, flipping it onto the FDM or SLA 3D printer, spending too much money on components, and ending up with something that may or may not work! Maybe plastic isn't the answer. Laser cutting and engraving really cranks out the concepts in a jiffy.
Before anything heads to the printer, it needs to be created. I use Shapr3D for designs requiring decimal-level precision. Blender is my go-to for things more organic. I'm a hard-surface modeler at heart.
As a kid I would never have imagined in my lifetime I would see 3D printing technology that was as accurate and affordable as today's FDM and SLA printers.
