1. A meltable 3D printer product filament having a length, comprising:
- a section of a first solid 3D printer meltable filament which is aligned in-line or perpendicular to the length of the meltable 3D printer product filament and having a first chopped end including a first shape comprising at least one planar surface that is angled relative to the length of the meltable 3D printer product filament;
a section of a second solid 3D printer meltable filament which is aligned in-line or perpendicular to the length of the meltable 3D printer product filament and having a second chopped end including a second shape comprising at least one planar surface that is angled relative to the length of the meltable 3D printer product filament;
wherein the first chopped end of the section of the first solid 3D printer meltable filament and the second chopped end of the section of the second solid 3D printer meltable filament are stacked and welded together and the first shape of the first chopped end of the section of the first solid 3D printer meltable filament and the second shape of the second chopped end of the section of the second solid 3D printer meltable filament are complementary to one another and define a transition between the section of the first solid 3D printer meltable filament and the section of the second solid 3D printer meltable filament.

Abstract
A 3D printer input includes filaments comprising separated layers or sections. These inputs particularly including filaments may be prepared by coextrusion, microlayer coextrusion or multicomponent/fractal coextrusion. These inputs and specifically filaments enable layering or combining different materials simultaneously through one or more nozzles during the so-called 3D printing process. These techniques facilitate smaller layer sizes (milli, micro, and nano) different layer configurations as well as the potential to incorporate materials that would otherwise not be usable in standard 3D printer methods.
