I have just returned from giving a lecture at the 2011 National Conference on Cast Iron Art.  I am still working on uploading the full powerpoint presentation from the lecture, but as a teaser here is the reference list that was most requested:

We are getting ready for an iron pour and finals are coming so look for the images from the powerpoint after May 15th.

Presentation at Ars Mathmatica in Paris

Recently Mark Ganter from University of Washington and Laura West from Fresno City College gave a presentation titled why collaboration matters at Ars Mathematica in Paris France.  We discussed the research we started before beginning to work together and more importantly the results of our collaboration.  Since beginning our work together, we have come up with an effective metal casting formula for 3D printing, several materials that print straight out of the bag and a material that casts both metal and glass (watch for upcoming post by Charlie Wyman) well straight out of the bag.  If you would like to see the powerpoint slide show of our presentation head to the post on Open3dp.

About Ars Mathematica from their website:

“2010 is the “International Year of Biodiversity“.
Considering that this is a particularly interesting topic for a meeting of artists and researchers, the association ARS MATHEMATICA proposes an exhibition and an international conference on the subject, opting for original perspectives. It is supported in this effort by the French Association of Exobiology, astronomers, historians, etc.., And by various institutions and companies involved in biology, 3D, high-tech…
The exhibition, conferences, and (subject) performances will be held from Saturday 23 to Sunday, October 31, the CARREFOUR NUMÉRIQUE (CYBERBASE) of the Cité des Sciences et de l’Industrie / UNIVERSCIENCE, 30, avenue Corentin-Cariou , 75019 Paris.”

You can find more information about Ars Mathematica here.  There is also a video of the exhibition and conference site which you can find here.

Ceramic Shell Metalcasting and 3D printing

One of the very first things I have tried regarding metal casting and the 3D printers is to invest the prints into ceramic shell for metal casting.  I am a metal caster by nature and so much of my journey with these materials has been in discovering uses for rapid prototyping technology as they apply to metal casting.  One of the earliest infiltrates for the material was wax.  Without an infiltrate, the materials tend to be very unstable and fragile (note that this changed with the work Mark Ganter and I have done with the cement based formula and hydroperm).  The standard powders also dissolve fairly easily in water, as do most plaster based materials.

This lead to first a proof of concept experiment where I invested one of my wax infused prints into ceramic shell (a very high temperature mold material that has almost no thermal shock).  I then burned it out and as expected the wax melted but the plaster remained.  The next step was to soak the mold in water overnight.  Between rinsing the mold in running water and a little assistance from a small wire, I was able to get all the plaster pattern out of the mold.  I got a casting that had a very high level of detail, which is to be expected from ceramic shell.

Since this point, I have experimented with various infiltrates.  Wax seems to work the best as it leaves a bit of a gap after burnout.  I have also worked with a few other powders in this process.  University of Washington’s VP2 works extremely well as the sugars dissolve quiet easily.

The series of photographs are primarily from student projects in various states of finish.  They were assigned to create a key chain on the computer using Solidworks.  Then we used the 3D printer to build the patterns and gated them up for investment in ceramic shell.  We followed this up the “lost powder” method of cleaning out the molds and poured bronze and aluminum into them.  There is a shot of our burn-0ut kiln as well as a shot of pouring.  I have also included a shot of one of the sculptures that I tested this process with.

“Additive Memories” solo exhibition of Laura West’s digital exploration of sculptural form

In addition to the group exhibition Rapid Premonitions, at  ArtSpace Gallery, Fresno City College is hosting a solo exhibition titled Additive Memories of the work of sculptor Laura West .  This is a collection of the best work completed by Laura West in the last few years that incorporates digital technology and 3D printing.  A majority of the work was completed in the last year alone.  Much of the work is a culmination of Laura’s spring 2010 sabbatical research which was conducted at Arizona State University’s PRISM Lab and University of Washington’s Solheim Lab as well as FCC’s Applied Technology RP Lab (special thanks to Ron Cerkueira, Dan Collins and Mark Ganter)

This prolific body of work  demonstrates the speed and efficiency that a sculptor can effectively use additive manufacturing technology to realize ideas and develop forms.  The sculptural work also showcases the beauty of the materials available to sculptors using powder based 3D printers.  The piece titled “Mine, Mine, Mine, Mine” is a tribute to sculptor Fred Wilson and used a color 3D printer to texture map photos into the surface of the figures.  “Falling Back Through Time” demonstrates the translucent nature of some of the materials.  “Conception of Hope” and “Eve’s Awakening” both explore the differences created by a change in scale.

Additive Memories runs along side the exhibit Rapid Premonitions (which reads much like a who’s who in rapid prototyping – both for artists and engineers).  It can be seen through December 9th 2010, with a reception on Thursday, December 2nd from 5-7pm in the ArtSpace Gallery at Fresno City College in California.

An exhibition of work created by sculptors and engineers who use RP based technology to create their forms opened this week in ArtSpace Gallery at Fresno City College.  These pioneering works show the wide variety of forms that can be created as well as an amazing array of materials that can be used.  This exhibit includes works based on both natural and mathematical forms.  Some of the work is completely computer generated where other work is based on 3D scan data or CT scans.  The materials include glass, ceramic, steel, stone, cement, plaster and even bone.

The exhibition will be on display through December 9th 2010 with a reception for the artists on Thursday December 2nd from 5-7pm.  The artists include:  Bathsheba Grossman, Ronald Cerkeuira, Dan Collins, Mark Ganter, Cynthia Handel, Bill Heiderich, Christian Lavigne,  Juliana Meire Do Valle, Mary Neubauer, Ronald Rael, Duane Storti, Eric West and Laura West.

Plaster Powder VOHP (Version “Out of the bag” HydroPerm)

Posted in 3DP Materials, rp/am sculpture, Uncategorized with tags , , , , , , , , , on November 6, 2010 by 3dpglass

by  Laura West and Mark Ganter

As a result of the collaboration between artist (and  a bit engineer) Laura West and engineer (and more than part – artist) Mark Ganter, we are making great strides in the Fresno City College Sculpture Lab and the UW Solheim RP Lab  for the past few weeks.  This went into high gear when Laura West came up to Seattle last week for Ars Mathematica and to finalize some research on the cemetenous material (see posts).  As you may have noticed, Mark made and amazing discovery and found a printing fluid (rice wine) that works straight out of the bottle.  A few days later, Laura began testing a type of gypsum cement straight out of the bag and Mark joined the party/followed suit/something like that literally within hours.

We have been both testing a number of different high strength specialty plasters and have found several to be amazingly successful. We are presenting last week’s winner.

The recipe is “There is no recipe“.   You simple purchase HydroPerm, cut open bag, and pour into machine.

It has good damp strength, great green strength, and air drying seems the best (although we have been known to bake a few).   The best part of VOHP parts is you can spray them with water OR gently wash them in water (and the parts get stronger)!  You can even use water based paints, stains, and varnishes.   The VOHP parts open up a new frontier in post processing options.

“Around midnight before Laura West was to leave her very productive visit at Solheim RP, she ran a test of a USG material called Hydroperm that is often used in metal casting.  It printed beautifully.  Good strength and very little binder migration (we call this “bloom”).  She then decided to run a small test mold and a few small sculptures.  Within two hours of starting the print, Laura took the test mold over to the metal casting lab and discovered that it does indeed hold up very well to cast metal.  This material is potentially even better than the cementenous formula.”

We have had successful results with a variety out-of-the-bag printing materials since we began our collaboration.   Some of them have potential for metalcasting (We would recommend waiting until we get past preliminary testing to try this – we promise to get you results soon).   As we test these and other new materials we will keep you posted on this site and open3dp.

"MesoBio" printed in Hydroperm by Duane Storti

 

 


Mark has been printing up a series of sculptures in Hydroperm for an exhibition in the ArtSpace Gallery at Fresno City College titled “Rapid Premonitions”  They are printing amazingly well. . .

"Moai Bowling" printed in Hydroperm by Mark Ganter

 

We think this is the best powder that we have found to date.   It works for part printing and it works for mold printing!!
