SPPL designs and manufactures the Drop On Demand 3D printer in which droplets of material are selectively deposited and cured on a build plate. Using photopolymers or wax droplets that cure when exposed to light, objects are built up one layer at a time. Dispenser systems are based on piezo - driven inkjet printing technology. The micro dispenser system is for non-contact dispensing of liquids in single droplets of volume ranges from 20 pl to 380 pl. It is possible to dispense liquids in single droplets or in series of drops with viscosities of 0.4 to 100 mPas.

SPPL designs, develops and manufactures the outdoor unit FSO communications setup, supporting 10 Gbps, with auto alignment feature complying to Make in India directive with more than 60% Indian Content. FSOC can deliver a wireless-access solution for quick deployment and with more bandwidth capacity, security features, and less power consumption than traditional point-to-point microwave links. With FSO, a high-power laser source converts data into laser pulses and sends them through a lens system and into the atmosphere. The laser travels to the other side of the link and goes through a receiver lens system. A high-sensitivity photo detector then converts these laser pulses back into electronic data that can be processed. Our system supports two optical channels, one at 1550 nm IR wavelength for data transmission and the other channel at 785 nm wavelength for implementing auto-tracking feature.
