Mono & Multi-filament LinesFor 3D print, product development, tests, upscaling.


Mono-filament lines - 3D filament line / strand lines

According to the respective customer requirement, COLLIN 3D filament and strand lines can flexibly be arranged with different machine elements. With these lines, customers produce filaments made of different materials, for example for the further processing in the 3D print procedure.


  • FDM Fused Deposition Modelling
  • FFF Fused Filament Fabrication

In this additive manufacturing process, where a workpiece in layers with meltable plastic or melted metal is produced, COLLIN filaments can be used. Moreover, this process is suitable for the production of round or flat strands as well as filaments.


  • Flexible material usage
  • Flexible strand shape
  • Highest precision regarding roundness
  • Constant diameter
  • Low space requirement
  • Flexibly applicable, also for coextrusion
  • High-precision diameter of the strands
  • Short purging times and material changes


  • Standard materials such as PP, PE, PS or PVC
  • Technical polymers such as PA, PET, PC
  • High-temperature polymers such as PEEK, PEKK, PES
  • Elastic materials, e. g. TPU, TPE

Multi-filament lines

The COLLIN multi-filament line is an ideal system for testing and developing multi-filament fibres. The performance of this compact, modular line is designed in such a way that it is perfectly suitable for pilot production as well as for production runs.

Thanks to very short cleaning cycles, also in case of frequent material changes, the system is extremely economical. The swivelling safety cover guarantees a high safety level for the operator and furthermore, the noise level is reduced. High-performance machine components, which can also be found in production machines, enable the transfer of the results to production lines.


  • Compact, modular line
  • Short cleaning cycles
  • Economic line
