Abstract
The invention provides a method for 3D printing a 3D item, the method comprising providing 3D printable material (201) and printing during a printing stage said 3D printable material (201), wherein the 3D printable material (201) comprises a thermoplastic material, to provide said 3D item, wherein the 3D item comprises an item surface, wherein the method further comprises providing a powder coating with a powder coating device (595) on at least part of said item surface during a coating stage. The invention also relates to the item manufactured by such method and to the manufacturing apparatus (500) used.
Claims14
A method for 3D printing a 3D item onto a substrate by means of fused deposition modeling using a 3D printable material that comprises a thermoplastic material, wherein the method comprises:
- a preliminary coating process during which a treated substrate is obtained by applying powder to at least part of the substrate;
- a printing stage during which the 3D printable material is printed using a fused deposition modeling printer to provide the 3D item onto the treated substrate, wherein the 3D item comprises an item surface, and wherein the method further comprises a coating stage during which a powder coating is provided with a powder coating process on at least part of the item surface;
- and
- wherein the printing stage comprises providing said 3D item with said item surface comprising a non-planar substructure, having a maximum substructure height (tsub), with superimposed on the non-planar substructure a fused deposition modeling related step structure having tops and bottoms, wherein the coating stage comprises providing said powder coating on said non-planar substructure with a powder coating thickness variation relative to the bottoms being equal to or smaller than the maximum substructure height (tsub) to enable the substructure to remain visible.
A method for 3D printing a 3D item onto a substrate by means of fused deposition modeling using a 3D printable material that comprises a thermoplastic material, wherein the method comprises:
- a printing stage during which the 3D printable material is printed using a fused deposition modeling printer to provide the 3D item onto the treated substrate, wherein the 3D item comprises an item surface, and wherein the method further comprises a coating stage during which a powder coating is provided with a powder coating process on at least part of the item surface;
- and
- wherein the printing stage comprises providing said 3D item with said item surface comprising a plurality of curved sections, wherein the plurality of curved sections, having a maximum curved section height (tsub), with superimposed on the non-planar substructure a fused deposition modeling a step structure having tops and bottoms, wherein the coating stage comprises providing said powder coating on said curved sections with an average thickness (t) of the powder coating relative to the bottoms being equal to or smaller than the maximum curved section height (tsub) to enable the substructure to remain visible.
