Improving Print Times for 3D Printing for the COVID War Effort

Lots of makers have been pressing their 3D printers into service for the COVID-19 war effort by volunteering to produce personal protection equipment (PPE) for frontline workers. What they are finding out is that it’s extremely labor-intensive to use a home 3D printer for small-scale production.

In this CNC Kitchen video, Stefan shows some tricks that he applied to reduce the print time of a face shield from 5 hours to 1 hour. This involved things like increased layer height, no skirt, increasing extrusion width, and decreasing the infill ratio to zero. There is some degradation in quality, but for this application, that’s fine.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
