This paper presents the design, fabrication and integrated 3d printed venturi vacuum gripper for an Industrial robotic pick-and-place operations require lightweight, high-response, and energy-efficient end-effectors to improve dynamic performance and productivity. Conventional gripping systems employing pneumatic cylinder-based mechanical grippers and external vacuum generators increase end-effector mass, system complexity, response time, and maintenance requirements. SLA 3D-printed Venturi vacuum gripper developed as an optimized alternative to traditional gripping mechanisms. The proposed system integrates vacuum generation, suction interface, and structural mounting into a single monolithic body using the Venturi effect, eliminating moving components and external vacuum units. Analytical modelling based on Bernoulli’s principle and continuity equations was used to size the Venturi geometry. The gripper was fabricated using Tough (ABS-like) SLA photopolymer resin and validated through structural simulation and experimental testing on an Epson T6 six-axis industrial robot. Experimental results demonstrated approximately 80% reduction in endeffector weight, improved vacuum response time, enhanced robot acceleration, reduced cycle time, and nearly 90% reduction in manufacturing cost compared to the existing pneumatic system.
