How’s That 2.5D Printer Working For You?
https://hackaday.com/2019/09/09/hows-that-2-5d-printer-working-for-you/
We’ve noticed a trend lately that advanced 3D printing people are calling their normal print setup as 2.5D, not 3D. The idea is that while the machine has 3 axes, the actual geometry generation is typically only in the X and Y axis. The Z axis simply lifts up to …read more (https://hackaday.com/2019/09/09/hows-that-2-5d-printer-working-for-you/)
