Do I Have to Dry my ABS Filament?

NETZSCH 3D Printing Myths Explained Drying ABS

Today, we answer the question if ABS filament absorbs water from the humidity in the air. Dr. Natalie Ruldolph explains why different plastics react differently to humidity in the environment and gives advice on what home users can do about it.

Material Jetting: Material Science in Additive Manufacturing

NETZSCH_Week 5_Additive Manufacturing

This week, we move back from thermoplastics to UV-curing resins, which are deposited in a different way. Together with binder jetting, material jetting is the only Additive Manufacturing process that can print in color. We introduce the process principle and look at benefits and applications of Material Jetting.

Investigating Dual Curing Resins for Digital Light Synthesis (DLS) with the Photo-DSC 204 F1 Phoenix

CLIP-NETZSCH-PhotoDSC

Photopolymers used in the Additive Manufacturing technology Digital Light Synthesis (DLS) are challenging materials. Little is known so far about the consequences of increased temperatures, e.g., due to higher room temperatures. A research paper aims to investigate the influence of temperatures on such dual curing resins and finds that the Photo-DSC is most effective in tracking the thermal conversion as well as to identify optimal exposure times.

Variations of Powder Bed Fusion: Material Science in Additive Manufacturing

NETZSCH_Week 3.2_Additive Manufacturing

Powder Bed Fusion (PBF) is one of the oldest Additive Manufacturing technologies invented in the 80s. However, its suitability for end-use parts and its constant innovations are driving this technology further ahead. This week we look at two important variations of Powder Bed Fusion.

How to Determine the Process Window for SLS Powders Using DSC

Powder Bed Fusion (PBF), often called Selective Laser Sintering (SLS), the component is built up in layers in a powder bed using a laser beam that passes over the cross-section of the layer to locally melt the powder. In order to characterize a polymer powder for its suitability for SLS and to determine the possible process window, Differential Scanning Calorimetry (DSC) is used. Learn how to set up and interpret the measurements!
