3D-Druck birgt verschiedene Gesundheitsrisiken: mechanische, elektrische und thermische Gefahren, Feinstaub- und VOC-Emissionen sowie der Umgang mit Chemikalien wie IPA und Aceton. Dieser Artikel beleuchtet potenzielle Risiken im FFF-Druck und zeigt, wie man mit einfachen Maßnahmen wie Gehäusen, Filtern oder PSA die Sicherheit deutlich erhöhen kann.
FFF 3D printers emit harmful particles and VOCs – in varying amounts depending on the filament used. A recent study compares modern materials such as PETG, ABS, and ASA. The result: PETG impresses with significantly lower emissions. The article explains the risks, measurement methods, and protective measures for safe printing.
The EU has a number of 3D printer resin manufacturers that have competitive prices compared to producers from overseas. Here is a list of available resins and their prices.
