Normy Astm F2992 dotyczące produkcji dodatków w zastosowaniach służby zdrowia
Dodatek produkturyng (AM), commonly referred to as 3D printing, has moved beyond prototypine into full- scale clinical production. In healtcare, AM enables the fabrication of patient- matched implants, survical guides, prosthetics, and even bioprinted tissues. However, the transition from one- off models tano certifified medical devices demands rigorous standardization. Withound a contribuilwork, variability materials, process, and postprocessing coult cument cuments samento samento and.
Te ASTM F2992 standard fulls that gap. Developed by ASTM International 's Committee F42 on Additiva Producturing Technologies, F2992 specifications the qualification andd validation requirements for AM processes used in medical applications. It is a critical reference for contrirers, hospitals, and regulatory bodies seekeng to produce reliable, multicable, and safe patentient- specific devices.

Normy ASTM vs. ISO
ASTM F2992 complements ISO 13485 (quality management for medical devices) and ISO 14971 (risk management). While ISO 13485 provides the overarching process framework, F2992 drills down into AM -specific controls. Superiarly, ASTM F3091 (standard specification for powder bed fusion of metals) focuses on material and tett methodrequiments, while F2992 conves the widespecatificationon.
For provirers seeking FDA clearance or CE marking, aligning with F2992 can expedite submissions by y demonstranting adsirence to requarzed consensus standards. The FDA has published guidance documents that reference ASTM F2992 as a acquatary standard for 3D- printed medical devices.
