3D printed resins may become brittle and may turn hazy or whitish when cleaned with conventional alcohols (e.g., ethanol or isopropanol IPA) and with many aggressive cleaning fluids. Cleaning chemistry can therefore directly impact both appearance and mechanical performance.
Comparison: alcohols vs recommended cleaning fluids
The following comparison summarizes conventional alcohols and the recommended 3Dresyns cleaning fluids for washing and cleansing 3D printed resins:
- Alcohols such as ethanol and isopropanol are flammable cleaning solvents. Depending on resin chemistry and cleaning conditions, they may contribute to whitening, haze or embrittlement; the effect should be evaluated on the specific printed material and workflow.
- Cleaning Fluid Bio is a cleaning auxiliary intended to remove uncured resin. In validated workflows it is designed to reduce embrittlement associated with conventional alcohol cleaning; clear parts may still show whitening. Consult the current product-specific SDS and processing guidance.
- Cleaning Fluid NW1 Bio is a bio-based cleaning auxiliary intended to remove uncured resin. It is designed for workflows seeking reduced embrittlement and reduced whitening relative to conventional alcohol cleaning; uncured or very tender prints may still lose transparency. Consult the current product-specific SDS and processing guidance.
- Cleaning Fluid UNW1 Bio is a bio-based cleaning auxiliary intended to remove uncured resin and support high optical clarity in suitable workflows. Performance depends on resin, cure state and cleaning conditions. Consult the current product-specific SDS and processing guidance.
- Cleaning Fluid UNW2 Bio is a cleaning auxiliary intended to remove uncured resin and support optical clarity in suitable workflows. Performance depends on resin, cure state and cleaning conditions. Consult the current product-specific SDS and processing guidance.
