Abstract

An apparatus for disposal of photocurable fluid waste may include a conduit for conducting photocurable fluid waste from a source of photocurable fluid waste; a dispenser for automatically dispensing a receptacle made of material that is impermeable to the photocurable fluid waste and that transmits radiation capable of curing; a welder or other sealing device for welding the receptacle to form a bag with a portion of the photocurable fluid waste inside; and a source of radiation for curing the photocurable fluid waste in the bag.

Claims (18)

1. An apparatus for disposal of photocurable waste comprising:

a conduit for conducting photocurable fluid waste from a source of photocurable fluid waste;

a dispenser for automatically dispensing a receptacle made of material that is impermeable to the photocurable fluid waste, the material transmitting radiation capable of curing;

a sealer for sealing the receptacle to form a bag with a portion of the photocurable fluid waste inside; and

a source of radiation for curing the photocurable fluid waste in the bag.

2. The apparatus of claim 1 , wherein the receptacle comprises two substantially parallel sheets, and wherein the dispenser includes two opposite reels around each of which one of the sheets is initially wound.

3. The apparatus of claim 1 , wherein the source of radiation comprises an ultraviolet radiation source.

4. The apparatus of claim 1 , wherein the source of photocurable fluid waste comprises a solid freeform fabrication system.

5. The apparatus of claim 1 , comprising a control unit.

6. The apparatus of claim 5 , comprising a sensor for sensing the quantity of the photocurable fluid waste in the bag.

7. A solid freeform fabrication system comprising a source of photocurable fluid waste and an apparatus for disposal of the photocurable fluid waste, the apparatus comprising:

a conduit for conducting the photocurable fluid waste from the source;

a dispenser for dispensing a receptacle made of material that is impermeable to the photocurable fluid waste, the receptacle comprising walls that transmit electromagnetic radiation capable of curing;

a sealer to form a bag from the receptacle; and

a source of radiation for curing photocurable fluid waste in the bag.

8. The system of claim 7 , comprising a sensor to sense the quantity of photocurable fluid waste in the bag.

9. The system of claim 7 , wherein the receptacle comprises two substantially parallel sheets, and wherein the dispenser includes two reels each dispensing one sheet.

10. The system of claim 7 , wherein the source of radiation comprises an ultraviolet radiation source.
