Recently I attended the National Conference on Cast Iron Art held at the historical Sloss iron foundry in Birmingham, Alabama.  I was lucky enough to present a lecture on my recent research into the application of Additive Manufacturing technologies to the process of Metal Casting.   What follows are the first 22 slides.  The next post will contain the final images.

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.

Photo of Charlie Wyman’s first bronze

This is a photo of one of the bronzes we poured when I was at UW.  It is printed from a file created by Charlie Wyman and was his first experience at pouring bronze.  It was poured into an open face mold using one of the materials we were testing.  Considering it was an open face mold, I think the results were quite good.

Look for a post that is coming soon about Charlies continued research with the use of hydroperm and glass.

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.

Cementenous atARS Mathematica

This post was written by Mark Ganter and edited by Laura West.

Things have been VERY busy in the sculpture lab at FCC as well at the engineering lab at UW these last days, Laura West and Mark Ganter both recieved an invitation to present physical work and provide a lecture at ARS Mathematica.  On a whim, Laura decided to try a new powder that she was testing straight out of the bag.  Mark rapidly joined in this effort to test this series of materials and has been furiously experimenting as well (it is such an exciting revelation that Mark started printing the next morning).  We will post our results soon and the cementenous metal-casting formula will come this week.

Since we will be discussing our cementenous material at ARS Mathematica, it seemed like producing new work in this material would be appropriate to show off at this juncture.

 

MesoBio – D. Storti @ 2010

The work was designed by Duane Storti and is called MesoBio.  It is a combination of the calcaneous and talus bones and a surface which is equal distance between the two bones.

 

Moai Jonchets – M. Ganter @ 2010

The work was designed by Mark Ganter and is called Moai Jonchets.   Jonchet is a French variant of the game called “pick up sticks”.

 

Backstack VI – L. West @ 2010

This work was created by Laura West, and is part of her “Backstack” series of works.  Most of this series plays with layered back forms, as if they were fallen leaves nesting upon one another.

Visiting Artist Cynthia Handel

Posted in rp/am sculpture with tags , , , on October 8, 2010 by skaad

This week we had a visiting artist come to the school. Cynthia Handel worked for two afternoon’s with Jason Rogoff, one of my students, Ron Cerkuria and I. The picture below demonstrates some of the results printed on the Applied Technology’s newer rapid prototyping machine. Especially considering Cynthia had no prior experience with additive manufacturing, the results are impressive.
