Carmaker XEV's new EV has many parts created by 3D printing

Posted Mar 18, 2018 by Ken Hanly
The LSEV as it is called took only 3 days to make and was produced by Italian car maker XEV and Polymaker a developer of 3D printing.

Another company - Rocket Lab's engines are constructed largely through 3D printing, specifically through electron beam melting, with its main prop valves, injectors, pumps, and engine chambers all 3D printed. The entire engine printing process takes just 24 hours.

The cost was $7,500 and all components were created by 3D printing except for the chassis, seats, and glass. It is hoped that mass production of the vehicles is soon coming. In all there were 57 different parts created through 3D printing.
The LSEV looks somewhat like the VW Smart Car
The car is shown on the appended video It is a two-seater. It has a top speed of just about 43 miles per hour. On a single charge it can travel about 93 miles.
The 3D printing plus the Polymaker materials have reduced plastic components of the car from 2,000 to 57.
The car weighs just 450 kilograms. Similarly sized regular cars weigh about a tonne. The 3D printing has meant a reduction of 70 percent in the cost. The 3D printing to produce the prototype took only a year for the design to become a reality whereas normally it can take up to five years.
The car will be available in Asia and Europe next year..
The 3D printed parts all are of Polymaker industrial materials
A website describing the Polymaker firm claims: Polymaker is a company committed to innovation, quality and sustainability, in the pursuit of producing safe and clean materials for the 3D printing industry. We do not simply adhere to current standards, but are surely becoming a market leader for quality in the filament industry. With a eight step quality control process, Polymaker’s filaments are not only guaranteed to have the best quality standards, but also provide innovative properties that help yield a better overall printing experience, ensuring the efficiency of 3D printers and empowering consumers to create strong, functional 3D printed products.
