High-End 2D and 3D Museum Sized Sculptures
For authorized wholesalers
 

These are some of our largest single-layer and 3D multiple-layer sculptures. Their larger size and complex internal patterns are prized by art collectors and home decorators. All sculptures are provided with custom walnut light bases with one or two LED strips. Standard colors are cool white, natural white, and "electric blue". Bases for 1.5" and 2" thick sculptures have two rows of LED's, and can be ordered with both strips the same color or a mix of two colors. Optional LED colors include red, yellow, and green. Multicolor color-changing strips are available on special order and higher cost.

We offer classical single-layer, complex 2-layer, and state-of-the art 3D masked sculptures. Our 3D masked sculptures uses lead masks on two surfaces to precisely control the regions of the specimen that are irradiated by the electron beam. As each specimen is passed through the beam, openings in the top mask permit electrons to charge up the acrylic below, while blocking electrons from the areas under the mask. 3D masked specimens are then rotated 180 degrees and irradiated again through the bottom mask. The result is a series of charged regions along two separate layers. Each charge layer is about 1/4" to 1/2" below the acrylic surface depending on the energy of the electron beam.

After discharging, the unmasked areas will contain discharges while the masked regions will not. By cleverly designing the masks and their relative alignment, we can also cause the two discharge layers to become linked by a large number of of smaller discharges. The result is an incredibly complex 3D discharge structure that is stunningly beautiful from all viewing angles. A diagram of the irradiation and masking process can be seen below:

Style 72 - 15" x 20" x 2", Two-Layer Discharge, No Masking
These sculptures combine the natural beauty of an unmasked sculpture with two interlinked charge layers. These are the largest sculptures we make. Because of the random nature of the discharges, there is considerable variation from specimen to specimens. One of these specimens is on permanent exhibit at the Chicago Museum of Science and Industry in the "Numbers in Nature" exhibit. Matching walnut base can be supplied with all cool white, natural white, blue LED's or a mix of any two.

MSRP: $2750.
US wholesale quantity price per sculpture and matching base: $1460.

Shipping weight ~40 pounds
