Bathsheba Grossman.

Bathsheba Grossman is an American artist based in Santa Cruz, California who creates stainless steel and bronze sculptures using computer-aided design and 3D metal printing technology. Her sculptures are primarily mathematical in nature, often depicting intricate patterns or mathematical oddities.

Bathsheba Grossman Sculpture 3D Printed 6 Feet Tall

We all know Bathsheba Grossman’s 3D Printed sculptures are massive in the world of math art but now they are just, massive… Thanks to the D-Shape 3D Printer and a valiant attempt on Indiegogo , Bathsheba’s Rygo sculpture has been 3D Printed 6 foot tall and has now made it’s way to Vancouver (only Canadian Shapeways users can imagine the UPS duties on THIS delivery).

Bathsheba Grossman, Math Sculptures. 3-D printed metal.

This is one of a delightful class of objects known as Seifert surfaces. Every knot and link (in mathematics knots are closed loops, links are assemblages of knots) has a continuous surface which it is the edge of. An introduction to these surfaces, along with free software to generate them, are at the SeifertView site. These surfaces are often beautiful, especially for symmetrical knots and links, and here I’ve produced one of the sweeter ones. This surface has three edges, each a simple closed loop, which are locked together in an ancient form called the Borromean Rings. Named after its use in an Italian coat of arms, these three rings are locked together inextricably although no two of them are linked. Their Seifert surface twists through the loops smoothly and gracefully, and I’m very happy with the organic mesh. It’s wide enough to let light through, while responding sensitively to the curvature and giving a tactile texture. (via Bathsheba Sculpture - Borromean Rings Seifert Surface)


Bathsheba Grossman - 3D Printing Lighting 

Artist Bathsheba Grossman has a great eye for beautifully symmetrical geometry. For more than twenty years, she has produced all kinds of complex, mathematical designs that she transforms into tangible objects through the technologically advanced process of 3D printing. In collaboration with .MGX—pioneers in 3D-printed designer lighting and furniture—many of Grossman’s designs are available as unique lamps and lighting systems. Flame,Quin, and Torus are just three examples of the stunning curves and textured twists that Grossman has imagined and then transformed into reality. The modern concepts, which illuminate any room with soft and interesting lighting patterns, are available as table lamps, floor lamps, and even pendants.

To make a sculpture, the artist first creates a concept as rough drawings and sometimes as molded modeling clay. Upon finalizing an idea, Grossman then builds the design digitally using CAD software. The final result is produced as a tangible object using a 3D printing machine, which layers metal into the proper shape and then fuses the metal together using heat. Once the metal is set, Grossman continues working with the piece, retexturing and smoothing it until these final sculptures are complete.

Klein Bottle Opener….

The problem of beer  That it is within a ‘bottle’, i.e. a boundaryless compact 2-manifold homeomorphic to the sphere.  Since beer bottles are not (usually) pathological or “wild” spheres, but smooth manifolds, they separate 3-space into two non-communicating regions: inside, containing beer, and outside, containing you.  This state must not remain.

A proposed solution  Clearly the elegant course is to introduce a non-orientable manifold, which has one side and does not divide 3-space.  When juxtaposed with the beer-bounding manifold described above, it acts to disrupt the continuity thereof, canceling the outdated paradigm of distinction between interior and exterior.  This enables the desired interaction between beer and self.

Implementation The Klein Bottle Opener1 shown above is an example.  It is palm-sized, durably constructed in stainless steel, effective2, and blissfully ergonomic.

Bathsheba Grossman, Noom, 3D-printed resin pendant. Her math-inspired jewelry and sculptures are very cool.

Splitting three times before rejoining itself, the Noom jewelry piece echoes a mathematical object called a wild sphere, and has duality as its theme. Where each of the tendrils meets, there is a twist: the halves reverse their symmetry, so that although one is notched and the other polished, they join together smoothly.

Women in 3D Printing: 5 Designers to Watch | All3DP
Think 3D printing is just about toys for the boys? Sites like Women in 3D printing prove it's not a male-dominated field. Here are 5 designers to watch.

It’s arguable that the 3D printing industry is more democratic than most. If you have an interest in design or computer modeling, then additive manufacturing technology is readily accessible in fablabs, schools and libraries to help make your vision a reality.

This openness, it turns out, is working. The excellent website Women in 3Dprinting is hosting interviews with women in the 3D printing industry, including their messages for other women makers, and it’s pretty inspiring.

Here’s more on five women in the design world to watch — all of whom are using 3D printing to expand the fields of art and design.


Bathsheba Grossman Metal Sculptures.

3-D printing in metal.

This piece is a complex knot, a single two-sided ribbon that follows itself through the form. Pulled out straight it would be over four feet long, but the steel-bronze composite metal used here gives it great toughness. This piece has one of my favorite symmetry groups, consisting of only the three 180° rotations about the axes. (via Bathsheba Sculpture - Universal Clef)

Symmetrical 3D Printed Lamps Based On Geometric Shapes
Known for her geometric works, artist Bathsheba Grossman has collaborated with MGX to produce these beautiful 3D printed lamps. To make them, Grossman first sketches a rough drawing, or uses modeling clay to get a feel of what she wants. After the design has been finalized, the artist uses CAD software to construct it digitally before handing it over to the 3D printer.
