WO 2006/086481 PCT/US2006/004450 METHOD OF DYEING A PHOTOPOLYMER PART.
BACKGROUND OF THE INVENTION This process defines a method for post dyeing stereo-lithography parts or other photopolymers in the form of custom ear shells for hearing aid applications. It can also be used as a secondary operation for adding color to any SL parts or other photopolymers which are made from suitable resins. The result of this process produces ear shells that demonstrate little to no noticeable bleeding of colorant when the shells are wiped with a cloth containing 100% isopropyl alcohol solvent.
The present invention relates to the creation of custom coloration of ear molds or ear shells manufactured using stereo-lithography (SLA) or other technologies such as Polyjet
T
and a clear photopolymer resin. Polyjet
T
M is described at httpi//www.2objet.com/Tech/Index.html. Presently, creating flesh tones or customerspecific ear shell or ear mold colors is accomplished using photopolymer resins within the SLA process that are pre-tinted or pigmented to the desired color. This results in ineffective use of the SLA machine in that all components produced within the machine at any given time can only be of one color, that of the resin which is loaded within it.
Furthermore, producing the variety of flesh tone colors within the world market means inventorying several different shades to meet customers' needs. This carries large inventor dollars, given that these rcsins are very expensive, involving high costs (for example, $3000 to $5000) to load one SLA machine with one color, in addition to the time involved changing from one color to the next.
The present invention addresses this problem by a method to dye ear shells, ear molds, or any photopolymer part manufactured with a clear photopolymer resin using a secondary dyeing process that can accurately produce the desired color while meeting bio-compatibility requirements.
SUMMARY OF THE INVENTION A method of dyeing a photopolymer part, comprising the steps of: selecting the dye color to be processed based on customer interest; mixing liquid dye and water to form a dye bath, WO 2006/086481 PCT/US2006/004450 warming the mixture; placing the photopolymer parts to be processed into the dye bath; removing the photopolymer parts from the dye bath; placing the photopolymer parts into a rinsing solution of detergent and tap water; removing the photopolymer parts from the rinsing solution; and Allowing the photopolymer parts to air dry.
A principal object and advantage of the present invention is that it permits the use of a clear photopolymer resin to produce any color desired by the customer.
Another principal object and advantage of the present invention is that is saves the expense of using colored photopolymer resins.
BRIEF DESCRIPTION OF DRAWINGS Fig. 1 is a flowchart of the method.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Preferred materials: Laundry detergent Tap Water solution Dye colorant, liquid or powder form Temperature controlled bath Thermometer Measuring Spoons Timer Tap water Microwave oven; 1200 watt WO 2006/086481 PCT/US2006/004450 Preferred Procedure: Dyeing Select the dye color to be processed based on customer interest.
Mix liquid dye and water to form a dye bath. Warm it up to the preferred temperature 140 7 degrees in the temperature controlled bath.
