First Claim
Patent Images
1. A method for additive manufacturing, comprising:
- depositing a first fiber composite filament on a build surface;
softening the first fiber composite filament on the build surface, wherein, after softening, the first fiber composite filament retains an ability to be shaped; and
flattening the first fiber composite filament.

13. A method for additive manufacturing, comprising:
-
delivering, without a change in cross-sectional area, a fiber composite filament onto a build surface; and reshaping the fiber composite filament by softening or partially melting the fiber composite filament, wherein, before reshaping, the fiber composite filament has a substantially circular cross section and after reshaping, the fiber composite filament is flattened. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for additive manufacturing, comprising:
-
depositing a second fiber composite filament on a first fiber composite filament; melting an upper portion, but not all, of the first fiber composite filament and melting a lower portion, but not all, of the second fiber composite filament, wherein, after melting the lower portion, the second fiber composite filament retains an ability to be shaped; and flattening the second fiber composite filament. - View Dependent Claims (20, 21, 22, 23, 24, 25)
