New Specification for Additive Manufacturing -- Finished Part Properties -- Titanium-27Niobium-21Zirconium via Laser Beam Powder Bed Fusion for Medical Implant Applications

1. Scope

1.1 This specification covers additive manufacturing of parts manufactured via laser beam powder bed fusion (PBF-LB) processing of Titanium-27Niobium-21Zirconium used in medical applications. Products built to this specification may require additional post-processing in the form of heat treatment, machining, polishing etc. to meet necessary surface finish and dimensional tolerances.
1.2 This specification describes the required facility, training, equipment, and processing requirements necessary to support the production of parts with properties and associated quality metrics outlined in a part classification structure.
1.3 This specification is intended for the use of purchasers or producers, or both, of PBF-LB Titanium-27Niobium-21Zirconium parts for defining the requirements based on part classification.. These requirements shall be agreed upon by the part supplier and purchaser.
1.4 Users are advised to use this specification as a basis for obtaining parts that will meet the minimum acceptance requirements established and revised by consensus of committee members.
1.5 User requirements considered more stringent may be met by additional requirements in the purchase order.
1.6 Units—The values stated in SI units are to be regarded as the standard. Other units are included only for informational purposes


additive manufacturing; powder bed fusion; PBF-LB; niobium


No such standard presently exists.

The title and scope are in draft form and are under development within this ASTM Committee.
