Castor

Castor Technologies Ltd., founded in 2017 and headquartered in Tel Aviv, Israel, provides decision support software for industrial 3D printing. The company was established by Omer Blaier and Elad Schiller. Blaier, the CEO, has an extensive background in the 3D printing industry, including a role as an R&D Product Manager at Stratasys, and holds a degree in Mechanical Engineering and an MBA in Entrepreneurship and Innovation. CTO Elad Schiller is an experienced software developer with a B.S. in Computer Science and an MBA in Finance. The idea for Castor emerged from Blaier's decade-long experience in the field, where he identified a gap in manufacturers' ability to keep pace with and leverage advancements in 3D printing technology.

The firm's core business revolves around a software platform that assists manufacturers in identifying which of their parts are suitable for additive manufacturing (AM) from both a technical and economic standpoint. This platform serves a diverse clientele, including startups and large enterprises in sectors such as automotive, aerospace, medical devices, and logistics. Castor's business model is centered on its software, which is available as a cloud-based service or an on-premise solution. The software analyzes thousands of CAD files or 2D drawings at once, a process that could take an engineer months to complete manually.

Castor's product performs a comprehensive analysis, evaluating parts for 3D printability, estimating costs, and providing a financial breakdown comparing AM to traditional manufacturing methods. The software suggests the most appropriate 3D printing technology and materials, performs geometric analyses, and identifies opportunities for redesign, such as weight reduction or consolidating multiple components into a single part. It also provides a failure simulation and a CO2 calculator to estimate potential emission reductions. The company offers several product tiers: CASTOR Light for those new to AM, CASTOR Enterprise for experts, and a White Label solution for customized platform adoption. Throughout its history, Castor raised approximately $5.9 million in funding from investors including Xerox, Evonik Venture Capital, and Asahi Kasei. However, citing mounting debt and a downturn in the 3D printing market, the company filed for court-ordered liquidation in July 2025.
