Abstract
The invention discloses a 3D printing powder supply amount calculation method and device, equipment, a medium and a product, and the 3D printing powder supply amount calculation method comprises the steps that the forming breadth of a current forming layer where a to-be-printed workpiece is located is obtained; the to-be-formed thickness of the current forming layer is obtained; a first powder supply amount is obtained according to the forming breadth and the to-be-formed thickness; obtaining a to-be-printed area of a current forming layer where the to-be-printed workpiece is located; the sintering shrinkage coefficient of the current forming layer is obtained; a second powder supply amount is obtained according to the area of the to-be-printed area, the to-be-formed thickness and the sintering shrinkage coefficient; and the total powder supply amount of the current forming layer is obtained according to the first powder supply amount and the second powder supply amount. By accurately obtaining the powder supply amount of the to-be-printed workpiece, the printing effect of the to-be-printed workpiece is guaranteed, and meanwhile the powder utilization rate is increased.
