Table 1 General Characteristics of Common 3D-printing Materials for Use in PPE
Material | Maximum Temp* | Basic Characteristics | Biocompatibility | Chemical Cleaning Concerns |
|---|---|---|---|---|
Polypropylene | 82.2°C Higher temps may compromise material | Relatively cheap thermoplastic. Can be used as both a plastic and a fiber | Currently used for: suture material, meshes, laboratory containers, drug delivery systems | Good chemical resistance (www.hmcpolymers.com), highly resistant to alcohol and solvents, negligible effects in bleach. |
PLA | 60-65°C Not suggested to heat sanitize | Good all-purpose FFF printing filament | Additives may not be biocompatible | Alcohol and solvents will degrade item |
TPE/TPU | Do not apply heat | More flexibility | Additives may not be biocompatible | Alcohol and solvents will degrade item |
