Nvidia Corp exhibited and demonstrated an AR HMD (AR glasses) that can be easily made by using a 3D printer at SIGGRAPH 2018 and delivered a lecture on an overview of the glasses.

Nvidia developed a technology to make optical parts that have complicated shapes (free forms) and are used for AR glasses by using a 3D printer, etc. The technology enables to prototype and test AR glasses equipped with optical parts having free forms in a short period of time and with a small capital investment, the company said.

It had been difficult to prototype optical parts having free forms in a short period of time and at a low cost because they require expensive manufacturing equipment.

Nvidia defines the market for GPUs targeted at VR/AR as an important growing field. Therefore, by developing manufacturing technologies to make it easier to prototype and test AR glasses, the company plans to promote the performance improvement of AR glasses, promote the use of them and expand the market for them.

Less than 1/50 capital investment, manufacturing time of one day

According to Nvidia, with the company's method, it is possible to prototype optical parts having free forms in a day with a capital investment of only US$15,000-20,000 while it required a capital investment of US$1-5 million and a period of six to eight weeks in the past.
