In the world of traditional manufacturing, producing large-format parts often comes with a long list of challenges—high costs, complex processes, limited design flexibility, and expensive iterations. To address these bottlenecks, TPM3D developed two high-performance dual-laser Selective Laser Sintering (SLS) 3D printers: the S600DL and P550DL.
With build volumes of 600 × 600 × 800 mm and 550 × 550 × 850 mm, these systems are purpose-built for one-piece printing of large, complex parts—while also driving a significant boost in production efficiency.
These machines have steadily gained traction across industries such as automotive, medical, and education, offering practical solutions to long-standing manufacturing pain points.
From April 8–10, TPM3D was invited to share its technical insights at the Tech Hub seminar during RAPID + TCT 2025, North America's premier additive manufacturing exhibition. The presentation focused on real-world applications of large-format SLS—highlighting how TPM3D’s solutions are already helping global manufacturers reduce lead times, cut costs, and expand design possibilities.
The S600DL, part of TPM3D’s Superior Series, is built to meet the highest European safety standards and has been certified by TÜV Rheinland (Pl-e level CE certification). With a build volume of 288 liters, it ranks among the largest SLS printers available. Equipped with dual lasers, dual dynamic focusing, and an intelligent coordinated scanning system, the S600DL ensures consistent part quality while improving throughput—making it ideal for large-format production and high-volume manufacturing alike.
The P550DL, from TPM3D’s Performance Series, is designed for both large single parts and batch production of smaller components. With two 140W CO₂ lasers and high-speed dynamic scanning systems, the P550DL achieves scanning speeds of up to 2×22 m/s—offering over 45% higher productivity compared to conventional SLS machines.
Manufacturing air ducts for metal 3D printers typically involves over a dozen complex steps—from drafting and cutting to folding, rolling, and welding—especially when internal multi-channel designs are required. TPM3D’s large-format SLS printers eliminate much of this complexity.
One industrial customer leveraged the P550DL to print a 3.5kg duct with intricate internal geometry in a single 25-hour run, achieving seamless one-piece construction that significantly reduced production steps and manual labor.
Large build volumes aren’t just for big parts—they also enable efficient layout for mass production. According to 3D Natives, the S600DL can print around 680 eyeglass frames in a single build (800 mm height), averaging 16 units per hour—twice the output of smaller machines.
Edser, a Spanish manufacturer of medical orthosis and insoles, turned to TPM3D to meet growing demand. With the S600DL, the company achieved substantial gains in both productivity and delivery speed, all while maintaining stable, uninterrupted operation.
As an Edser spokesperson noted, "It (TPM3D) is the only 3D printer in the market with such capability in volume printing, for manufacturing large parts and revolute the orthotic world. Enables the making of designs in one piece and fully adapted with complex geometries."
From producing structurally complex, large-scale parts to driving efficient small-part batch production, TPM3D’s S600DL and P550DL are reshaping expectations in additive manufacturing. Backed by robust engineering and proven field performance, these machines are helping global manufacturers realize smarter, faster, and more flexible production.
