Large diameter feedstock for extrusion-based additive manufacturing
Feedstocks are provided for use in the additive manufacturing of three-dimensional objects via extrusion-based techniques, such as Fused Filament Fabrication (“FFF”) or Fused Deposition Modeling (“FDM”). Generally, the feedstocks may be in the form of substantially continuous filaments and/or in the form of rods of specified length, with diameters in excess of 3.5 mm.
1. A feedstock for an extrusion-based additive manufacturing process, said feedstock comprising one or more continuous filaments, one or more rods of a specific length, or a combination thereof, wherein said filaments and said rods have an average diameter of at least 3.5 mm, wherein said filaments and said rods are formed from a polyester, a polyamide, a polycarbonate, or a combination thereof, wherein said filaments and said rods have a monocomponent configuration.
2. The feedstock according to claim 1 , wherein said filaments and said rods have an average diameter of 4 to 15 mm.
3. The feedstock according to claim 1 , wherein said filaments and said rods have an average diameter of 4 to 7 mm.
4. The feedstock according to claim 1 , wherein said filaments and said rods have an average diameter of 5 to 7 mm.
5. The feedstock according to claim 1 , wherein said feedstock comprises said filaments, wherein said filaments consist of said polyester, said polyamide, or said polycarbonate.
6. The feedstock according to claim 1 , wherein said feedstock comprises said rods, wherein said rods have a length in the range of 100 to 1,000 mm, wherein said rods consist of said polyester, said polyamide, or said polycarbonate.
7. The feedstock according to claim 1 , wherein said feedstock consists of said filaments, said rods, or a combination thereof.
8. A feedstock for an extrusion-based additive manufacturing process, said feedstock consisting of one or more continuous filaments, one or more rods of a specific length, or a combination thereof,
wherein said filaments and said rods have an average diameter of 4 to 15 mm,
wherein said rods have a length in the range of 100 to 2,000 mm,
wherein said filaments and said rods consist of a polyester, a polyamide, a polycarbonate, or a combination thereof,
wherein said filaments and said rods have a monocomponent configuration.
9. The feedstock according to claim 8 , wherein said filaments and said rods have an average diameter of 5 to 7 mm.
10. An additive manufacturing process comprising:
(i) providing a feedstock comprising one or more continuous filaments, one or more rods of a specific length, or a combination thereof, wherein said filaments and said rods have an average diameter of at least 3.5 mm, wherein said filaments and said rods are formed from a polyester, a polyamide, a polycarbonate, or a combination thereof, wherein said filaments and said rods have a monocomponent configuration; and
(ii) subjecting said feedstock to additive manufacturing to thereby produce a three-dimensional object.
11. The additive manufacturing process according to claim 10 , wherein said additive manufacturing comprises Fused Filament Fabrication or Fused Deposition Modeling.
12. The feedstock according to claim 1 , wherein said filaments and said rods consist of said polyamide, wherein said filaments and said rods have an average diameter of 5 to 7 mm.
13. The feedstock according to claim 8 , wherein said filaments and said rods consist of said polyamide, wherein said filaments and said rods have an average diameter of 5 to 7 mm.
