Although the Colossus may be the largest 3D printer at Formnext 2018 in Frankfurt, Germany, the Nexa3D NXE400 is probably the fastest. The NXE400 is an SLA 3D printer designed for ultra-fast prototyping and part production. SLA (stereolithography) printing is arguably the most accurate form of 3D printing, and it is also the fastest. Avi Reichental, co-founder and executive chairman of Nexa3D, said: “We are very excited, proud and humble, and have become the team that has broken the speed, scale and cost barriers that have limited our industry growth for decades. This development is end-user, strategic cooperation. Highly praised by partners, distributors and investors.”
The Nexa3D NXE400 prints six times faster than other printers in its class, at a speed of 1 cm per minute! This means that one foot of the part can be printed in half an hour, no matter how complex it is. This is close to the current TV sci-fi printing speed. To explain how they achieve this rugged feat, a brief introduction to the functionality of the SLA printer will help.
