Influence Of Dried Filament On The Print Quality

• 

  Extrusion Quality

  Almost all technical high-performance materials are hygroscopic and interact with the water content in the ambient air. Therefore, they must be dried before use in the 3D-printer to remove moisture. Moisture-free filaments have no bubbles in molten form. This prevents poor optical properties and component defects.

  Surface Finish

  3D-printed parts made of dried materials are generally smoother and thus meet higher requirements for dimensional accuracy and surface quality.

  Oozing and Stringing

  With pre-dried filaments, the oozing out of the nozzle is reduced during the printing process and the stringing is significantly reduced.

  Mechanical Properties

  3D-printed parts from dried filaments exhibit stronger mechanical properties and less structural failures.

  Interlayer Adhesion

  Dry filament usage will avoid hydrolysis, which deteriorates mechanical properties of polymers and can lead to delamination during printing.

  Cosmetic Defects

  Dry filament usage eliminates a number of moisture-related 3D-printing defects.
