Using AM Technology to Disrupt the Scientific Hardware Industry

The SolutionAronson realized the only way he could fabricate his device affordably was to utilize a 3D printer. He had heard about Markforged from a friend, and decided to get a benchmark part made. After finding the material to be strong enough for his device, he purchased a Markforged desktop printer to create hardware components for the device. The team iterated through dozens of prototypes, yielding a functioning prototype in just three months. Aronson bought six more Markforged desktop printers to keep up with the demand for his product, and started to create 3D printed end-use components. “If we weren’t able to print and use parts with this, the business wouldn’t have started,” Aronson says. Markforged printers allow Aronson and his team to create parts with precision that can easily interact with delicate and expensive optical instruments without scratching or breaking them. The most significant and the largest of these parts is the optical housing for the device — a single piece that holds all the optical instruments with a high degree of precision. The entire component takes just over two days to print, and costs a little over $50 in material. The optical housing isn’t the only production part printed on his Markforged printers. Aronson estimates that around 90% of the printers’ usage is printing end-use parts for the device, with 17 parts fabricated on the printer and three structural metal parts traditionally manufactured. “Really this is a 3D printed system with a few metal parts,” says Aronson. Neurophotometrics has been able to compete with giant companies by changing the price point of scientific hardware — all thanks to additive manufacturing. In the first two years of operation, Aronson estimates Neurophotometrics has over 14,500 printer hours and has gone through over 100 spools of filament.

Looking Ahead
Neurophotometrics currently has its devices in several companies around the world. The team has become more versatile and has shipped its product across 10 countries, including the United States, Canada, Germany, South Korea, and Australia, and have recently introduced their first Japanese distributor. Aronson expects to add several more Markforged printers to his print farm to keep up with growing demand, and says Markforged will continue to play a central part in his business.
