Abstract
A method of manufacturing a 3D object, the method comprising: providing a powder layer of powder particles; building up a new layer of the 3D object by directing a beam of radiation towards the powder layer to melt the powder particles at predetermined positions to build up the new layer of the 3D object on re-solidification; and forming a pore in the new layer at a preselected position by using a beam of radiation to form and subsequently collapse a melt pool so as to trap gas as a pore in or below the new layer at the preselected position on re-solidification.

A method of manufacturing a 3D object, the method comprising:
- providing a powder layer of powder particles;
- building up a new layer of the 3D object by directing a beam of radiation towards the powder layer to melt the powder particles at predetermined positions to build up the new layer of the 3D object on re-solidification;
- and
- forming a pore in the new layer at a preselected position by using a beam of radiation to form and subsequently collapse a melt pool so as to trap gas as a pore in or below the new layer at the preselected position on re-solidification.
A first 3D object comprised of a base material including a plurality of pores at preselected locations in the base material, wherein each of the plurality of pores has a volume equivalent to a sphere with a diameter in the range of 2 to 150 μm as measured by X-ray microCT under ISO 15708-3:2017, and has a density of less than 50% of the base material and a second 3D object comprised of a base material including a plurality of pores at preselected locations in the base material, wherein each of the plurality of pores has a volume equivalent to a sphere with a diameter in the range of 2 to 150 μm as measured by X-ray microCT under ISO 15708-3:2017, and has a density of less than 50% of the base material, wherein the preselected locations in the first and second 3D objects are substantially the same.
