Abstract

According to some aspects, a storage unit for storing a photopolymer resin is provided. The storage unit may comprise a photopolymer resin, a bottom face comprising at least one region of actinically transparent material, the actinically transparent material being actinically transparent with respect to the photopolymer resin, at least one wall extending upwards from said bottom face comprising at least one region of actinically opaque material, the actinically opaque material being actinically opaque with respect to the photopolymer resin, and a lid comprising the actinically opaque material and removably connectable to the at least one wall.

First claim

What is claimed is:

1. A photopolymer storage unit, comprising:
a bottom face including a bottom surface and an actinically transparent surface recessed toward an interior of the photopolymer storage unit relative to the bottom surface;
at least one wall extending upwards from said bottom face,
wherein the photopolymer storage unit is configured to removably attach to an additive fabrication device.

2. The photopolymer storage unit of claim 1 , wherein the at least one wall includes a spout.

3. The photopolymer storage unit of claim 1 , further comprising one or more stopping features configured to limit motion of the photopolymer storage unit during attachment of the photopolymer storage unit to the additive fabrication device.

4. The photopolymer storage unit of claim 1 , wherein the bottom surface and the at least one wall are actinically opaque.

5. The photopolymer storage unit of claim 4 , wherein the bottom surface and the at least one wall are opaque to at least a first wavelength of light and wherein the actinically transparent surface is transparent to at least the first wavelength of light.

6. The photopolymer storage unit of claim 1 , further comprising a lid configured to be removably attached to the at least one wall.

7. The photopolymer storage unit of claim 6 , wherein the lid comprises a plurality of tabs adapted to be actuated to create a locking engagement between the lid and the at least one wall.

8. The photopolymer storage unit of claim 6 , wherein the lid includes a raised portion configured to mate with the bottom face of a second photopolymer storage unit.
