Glowforge describes their product as a "3D laser printer," but it is the same class of device as what the rest of the world refers to as a CO2 laser cutter and engraver. The Glowforge originally went on sale as a pseudo-crowdsourced project by soliciting pre-orders in Sept. and Oct. of 2015 with an "expected delivery" by Dec 2015. They received $28M in fully-paid pre-orders during the phase.
Many delays and feature-changes ensued, and the first finished units were not shipped until July 2017. Most of the backlog was fulfilled over the following year, but some international orders still lingered.
