The next logical extension of the Laser Collage process is something I call The Eric Carle Method. Children’s book author Eric Carle is known for his collage are using his hand painted papers. The main difference is that you are adding paint to the process rather than using ambient papers or recycled materials for the collage art.   Squid Attack 02   I had a clear idea of what I wanted in this design and drew the squid and submarine in Adobe Illustrator using the pen tool. That step took me at least three hours. I used a Gelli Arts soft monoprinting plate to roll acrylic paints onto and made the color combinations I wanted for scene, aiming for a red / blue /yellow primary color scheme. This version pops out and seems more playful. I may try a version with darker colors and low intensity hues to see if it looks more realistic. Today, I was just aiming for a fun picture. My paper was an 80# weight cardstock with a hard, smooth finish. This paper held the acrylic paints well with little to no warping and dried fast. I used the Epilog Mini laser to cut and etch my drawings. The vector cutting was at speed 20 / power 25 / hz 500. Only the slightest edge of the design had a sign of the laser, literally just the plane the thickness of the paper; viewed from above there was no visible scorch. The acrylic paints had some resistance to being etched and I used speed 100 / power 50 to etch the eye and a few lines.   Squid-Attack-03   Matte acrylic gel medium glued the arranged layers together. Boards and wax paper were helpful to press the art flat. I used a Micron pen to fill in the etched lines on the body and for the eye and some thinned white acrylic paint for highlights and reflections. I’m really happy with how my giant squids came out. This was unfortunate for anyone who was at the space today because I went around with them when they were done. It’s not often that someone comes up to you and asks, “Have you seen my squids?” File that under the heading “Because: Hackerspace.”

Laser Collage: An art form for and from the hacker/maker community

Art-Sharks-Shellie-Lewis-2014-WEB

Art Sharks by Shellie Lewis, paper collage and laser technology, 6×8 inches, 2014.

Every artist hopes to come up with an original idea, to be on the forefront of the next big idea or movement. This is hoping against the odds as the past two centuries have seen an explosion of movements, styles and schools of thought that rained down in Western art like a meteor shower.  Fauvism, Cubism, Futurism, Surrealism and many other modern movements would originate, peak and dissipate rapidly, lasting a few decades or less. World Wars arose and crushed other movements like Romanticism or Der Blaue Reiter. There are many forms of art that we can reach into the past and mine: appropriate and carry on with. In fact, schools of American Impressionists are still working in different lineages since the 19th century from William Merrit Chase, John Singer Sargent and other painters. Waves of more recent artists have imitated Picasso and Warhol. For the contemporary artist hoping to create something unique, there is very little chance of inventing something new.

Current technologies are opening the door for innovation. Many times, I am seeing where maker technologies are being used to vary production of traditional physical media arts and crafts. Laser cutters are being used to etch intaglio printmaking plates, textiles are incorporating electronics and lights, robotics are animating sculpture, and digital media is widely available. Video, animation and interactive arts are now accessible to most of the general public. It’s an exciting time to be involved in the hacker/maker culture.

I may have come upon an idea that can become an art style uniquely ours: Laser Collage. I have always enjoyed collage for drawing on images and materials readily available around people. At its most basic level, the only thing needed to create collage art is some form of glue or paste. Good scissors, a razor blade or hobby knife are helpful. Throughout art history, most fine art collage works have followed their siblings in painting and drawing, largely staying within the bounds of a rectangle or square. Contemporary painters such as Elizabeth Murray, Frank Stella and Ellsworth Kelly set their abstract works free from the tyranny of the rectangular border. Now artists in the hacker/maker community can liberate the collage from the rectangle.

Laser Collage innovates through using two things well loved in the hacker/maker community: digital vector art and laser cutters. By using a vector design, the exterior borders of a collage art can take any form. Art works can have further elements by using raster etching as well as the vector cutting abilities of the laser. Artists can utilize recycled materials. I am excited by the possibilities for this medium. Functional and three dimensional designs are possible beyond flat two dimensional art works. Laser Collage is an art style that frees the collage art to be any size and shape. This is an art form that can be uniquely ours.

My experiments with these samples were basic in materials. I used recycled chipboard (i.e. common food packaging like cereal boxes) and a simple glue stick. I avoided PVA [polyvinyl acetate] “white” glue since it is similar enough to PVC to be a possible problem with dangerous fumes from a laser. Any glycerine and wheat-based adhesive like glue sticks, YES! Paste or acrylic-based adhesive like gel medium should be safe for laser cutting.

Using the Epilog Mini 30W laser, I got an excellent cut through the variable thickness layers of paper and chipboard using a vector setting of speed 15 / power 100 / hz 2500. The edges have a little scorch, so you may want to adjust your cutting power or increase the speed. Raster etches were at speed 40 / power 100. Etching has interesting potential for etching your collage in a fashion that lower layers reveal different colors in the design. My approach was to cover the chipboard surface first in collage elements with my glue stick and then place it in the laser cutter for cutting and etching. The artist controls the materials used, color palette, range of colors, form of the collage pieces, flow of the collage design, number of layers cut by the laser, laser etching elements and the ultimate size and shape of the border.

Creators without access to a laser cutter could use vector designs using an electronic cutter like a software hacked Cricut, a Silhouette cutter or similar machine. I have often seen owners of these tools cut elements to incorporate into collages, artist books and paper arts, yet still retain the linear borders of a square or rectangle. Shaped collages would be restricted by the width of the cutting machine which is usually around 12 – 15 inches, whereas laser cutters tend to have larger cutting dimensions. I am most excited by the potential for the medium through laser cutting technology because a laser cuts details a lot finer than a metal blade can and etching adds more depth to the design.

Laser Collage is my humble offering to the continuum of Western art history. Maybe I will be the only one interested in this form but I am putting the concept online hoping other people will want to try it. Mixed media elements including paints, markers, pens and pencils can also be easily incorporated. Feel free to experiment with the process on your own and please respond if you want to show your work in this medium, if you have any discoveries or develop a variation of the technique.

Pumping Station: One Design Contest!

We’re looking for designs to turn into Tee-Shirts, Buttons, and Stickers for giveaways(buttons and stickers) and sale(tees) at Pumping Station: One! Draw, vector, and photoshop your heart out and show us what Pumping Station: One means to you!

The first wave is a call for submissions, this will last until the 31st of August, followed by an open voting period until the 30th of September. Finally, the board will order everything and get it shipped to the space.

Guidelines for submissions:

  • Designs are for the tees, buttons, and stickers. Unless you think the design will be optimized to look good in all three formats, I suggest you edit your designs for each application. By all means, have the same elements in each, but keep in mind that the button has less space for detail than the shirt.
  • Unless you’re designing in vector format, make sure your original copy will be of sufficient size and detail. the canvas you work in should be about 10″ wide by 15″ tall and at LEAST 400PPI.
  • Be excellant! No inappropriate themes, remember that PS: One is a safe space, and we don’t want to ban our own merch from the space.

Demo Day: Ancona Edition

Soldering kidHello everyone! You know those demonstration days we did for the library a month or so back? Well, Elizabeth and I thought it’d be a good idea to reach out to the school where we teach the after school Maker class and do the same. We thought that having an open demonstration for parents, kids, and faculty would be a great idea to cultivate our image as a valuable educational resource for kids and adults alike.

We want to showcase the value of Maker culture and skills in the development of kids in gradeschool. We want to be entertaining, so we plan on doing the Learn to Solder kits, Laser cutter demo, possibly some 3D printing demos, and the like. If anyone has any demonstrations that would be appropriate for kids, and would like to help out by hosting that demonstration, please come.  And if you just want to be there and mingle with the parents, maybe bring your own kids, show them what our community means, and what it means to your kids, please come.
The event is Sunday, June 8th, from 2-4pm, at Pumping Station: One.
