Detoxification of solid freeform fabrication materials

A method of forming and detoxifying a three-dimensional object for long-term dermal contact biocompatibility, the method comprising:

• forming a preliminary object in successive layers with a polymerizable build material in a layerwise fashion, the preliminary object containing cytotoxins;
• nullifying the cytotoxins in the preliminary object to establish a biocompatible three-dimensional object.

A method of forming and detoxifying a three-dimensional object formed by solid freeform fabrication, the object being detoxified for at least long-term dermal contact biocompatibility, the method comprising:

• forming a preliminary object in successive layers with a build material in a layerwise fashion, the preliminary object containing cytotoxins;
• subjecting the preliminary object to ultrasonic stimulation in a medium for a sufficient period of time so as to nullify the cytotoxins in the preliminary object and thereby establish a biocompatible three-dimensional object.

• forming a preliminary object in successive layers with a build material in a layerwise fashion, the preliminary object containing cytotoxins;
• subjecting the preliminary object to chemical extraction in a medium for a sufficient period of time so as to nullify the cytotoxins in the preliminary object and thereby establish a biocompatible three-dimensional object.
