With the rapid development of humanoid robots, intelligent prosthetics, automated assembly, and related fields, the demand for micro multi-axis force sensors continues to grow. In precision manufacturing, the dimensional accuracy of micron-level components imposes stringent requirements on production processes, while single-part production models struggle to meet the capacity demands of large-scale applications. Recently, BLT has made new progress in the mass production capability of micro multi-axis force sensors using metal additive manufacturing technology.
01 Single Batch of 972 Parts per Plate – Unlocking Mass Production of Miniature Parts
Take Haptron Scientific’s Photon Finger-B micro multi-axis force sensor as an example. The external dimensions of a single Photon Finger-B sensor are only 8.5 mm × 8.5 mm × 6.91 mm, making it a typical micron-level component. With BLT’s large-format, high-precision printing equipment and process optimization, the number of parts printed per batch has increased significantly from dozens in the past to 972 parts per full plate. High consistency is maintained across all components, laying a process foundation for batch applications.

The as-printed surface roughness reaches Ra 2–3, and forming accuracy can be controlled within 0.05 mm, meeting the tight tolerance requirements for critical feature dimensions of micro sensors.
02 Stable Mass Supply for Photon Finger Series-Thousands of Units Delivered Cumulatively
Haptron Scientific’s Photon Finger series features true, stable, precise, and linear force perception capabilities, supporting tasks ranging from fragile object grasping to heavy-load interaction. To meet these high-performance requirements, the physical structure of the sensors must exhibit high strength, lightweight characteristics, and high consistency. To date, utilizing metal 3D printing processes, BLT has cumulatively delivered thousands of units across various models—including the Photon Finger-B, Photon Finger-S, and Photon Finger Max—providing reliable manufacturing support.
Metal additive manufacturing technology is transitioning from prototype manufacturing to genuine mass production. Particularly in the field of micro-precision parts, the advantages of “high precision, high consistency, high material utilization, and short process flow”are being fully realized. BLT will continue to provide more diverse and efficient mass production solutions for fields such as micro-precision sensors.
