Main Features of the PostPro SF100

The PostPro SF100 is the result of over five years of academic research and three years of industrial development, validated in real-world industrial-scale additive manufacturing applications. Its patented technology not only smooths external surfaces but also seals internal cavities of printed parts, significantly enhancing their mechanical and functional properties.

Compatible with over 100 thermoplastic polymers, including nylons and flexible TPU/TPE materials, the system works with powder-based and extrusion 3D printing technologies such as SLS, MJF, HSS, and FFF. Its advanced automation enables seamless integration with MES and ERP systems, essential for digital management in production plants under the Industry 4.0 paradigm.

The design of the PostPro SF100 prioritizes safety and sustainability: its closed system prevents emissions and waste, ensuring operator and environmental protection, while full recycling of consumables ensures an eco-efficient process. Additionally, its Full HD touch interface, RFID recognition for consumables, and access control optimize daily operation, minimizing errors and downtime.

With external dimensions of 830 × 1,400 × 1,830 mm, weight of 850 kg, and a processing chamber capacity of 96 liters, the PostPro SF100 combines robustness with a compact footprint to facilitate integration in industrial mass production environments.

Success Story: Prototal UK and Their Workflow with PostPro SF100

Prototal UK, a company specialized in additive manufacturing, has incorporated the PostPro SF100 into its post-processing line to transform 3D printed parts. Alongside other complementary AMT systems, such as the DP MAX for efficient powder removal and the SB for consistent shot blasting (or sandblasting), Prototal has significantly optimized surface quality and production scalability.

This integrated workflow has enabled Prototal UK to improve finish uniformity and reduce processing times, resulting in a greater capacity to fulfill large-scale orders and meet the highest standards of its industrial clients. Prototal’s real-world experience confirms that the PostPro SF100 technology not only delivers superior finish but also substantially improves operational efficiency.
