Technical parameters of 3D printing
1. Metal 3D printer maximum molding printing size: 280x280x350mm;
2, 3D printing layer thickness: 0.02mm~0.04mm;
3, 3D printing accuracy: typical accuracy: ± 0.02-0.05mm (accuracy is related to geometric shape.It varies according to product size, 3D printing direction, materials and post-processing methods.;
4, later processing: high temperature annealing, polishing, welding and other processing;
3D printed material characteristics
3D printing metal powder titanium alloy TI64, this well-known light alloy is characterized by excellent mechanical properties and corrosion resistance plus low specific gravity and biocompatibility.This material is suitable for a variety of high performance engineering applications, such as in aerospace and racing, and can also be used to produce biomedical implants (Note: subject to compliance with statutory certification requirements where appropriate).

* Note:
1. According to Annex D of ISO 6892-1:2009 (B), proportional specimen, diameter tensile test of neck area 5 mm (0.2 in.), original gauge length 25 mm (1 in.).
2. The samples were treated in an inert atmosphere of argon at 800℃ (1470 °F) for 4 h.Mechanical properties show a minimum value indicating that the mechanical properties exceed the minimum required material specifications.ASTM F1472-08.This is achieved by meeting these minimum values, which are also standard ASTM B348-09 and ISO 5832-3:2000.According to EN ISO 6507-1
3, Vickers hardness measurement (HV) of the polished surface.Note that the measured hardness can significantly depend on how the sample is ready.
