3Dresyns can consult you to design the safest 3D resin, printer setup, and workflow for each biomedical application, as well as the safest printing and post-processing protocols to ensure maximum polymer conversion and minimum residuals, byproducts content, and extractability during usage by the human body.
Why safety requires protocols and process control
Safety can only be ensured through adequate material design, monitoring and control of both the printer and the light box units, and well-defined cleaning processes. Protocols are required to prevent external contamination caused by production malpractice and to ensure impurities and residuals are extracted before use.
Residuals should be removed during post-processing or during sterilization, and not during final use by end users, to reduce the risk of absorption by the body (e.g., mucosa exposure in dental applications).
Risk context: extractables, leachables, residuals, and byproducts
Safe and detailed printing, post-curing, and post-processing protocols are required to ensure that biomedical and food packaging printed materials are safe for final users. Consumers can be at risk of absorbing extractables, leachables, residuals, or byproducts when unsuitable resins are selected and when adequate controls and protocols are not implemented by manufacturers.
