Barry Romich Laser Engraving
In early 2009, I acquired an Epilog Zing 35 watt laser engraver. www.epiloglaser.com and have been having fun with it ever since. I bought a second unit in 2013, a Zing 30 watt. They are used primarily for manufacturing products, signage and other items and generally for supporting non-profit organizations. As an example, several of the components of the AAC Institute ADA-CAT (Americans with Disabilities Act Compliance Assessment Toolkit) are fabricated using a laser engraver.
The working area is 12" x 16". They have two modes of operation, raster and vector. In raster mode they will engrave text and graphics in a manner similar to how an inkjet printer works, by scanning left to right with a specified resolution up to 1000 dots/lines per inch. I've engraved natural, finished and painted wood, clear acrylic, anodized aluminum, coated galvanized steel, pencils, flooring material, slate, engraving laminate, and more.
In vector mode, generally used for cutting, the laser will follow lines. I've used this feature for cutting wood, acrylic, thin polycarbonate, fish paper, heavy paper, double sticky foam gasket, and other non-metallic materials up to 1/8" thick.
Here are a few examples of things I've engraved and cut.
The above assortment shows a variety of things that can be done with a laser engraver. The base material is laminate flooring, which is available at little or no cost. The green and yellow items are standard laminated plastic engraving material. The surface is removed in the engraving process to expose the core material of contrasting color. With many materials, the laser can cut holes and other shapes and then cut the finished piece out of a sheet.
The box below is 2" x 2" x 1" and is made of 1/8" clear acrylic sheet. It is made using a clever free web-based program called MakerCase. (www.MakerCase.com). A tutorial sheet was prepared by the nice people in the Prentke Romich Collaboratory of Think[box] at Case Western Reserve University. The program asks for the desired dimensions of the box, the material thickness, and the type of joint and generates a file that can be downloaded and opened using Corel Draw. The six sides of the box can be moved around to fit on the scrap acrylic you have available and edited, if desired. Just make sure that all the cut lines are "Hairline" thickness.
My primary source for standard engraving material is Johnson Plastics. They also have various other materials useful for laser engraving. The brass item below was placed over a donated drinking fountain at the Creston Community Center.
I did the above on baked brown painted aluminum flashing. The laser burns off the paint. The same technique works well with galvanized steel roofing. The color coating, a good contrast with galvanize, is removed to expose the galvanize. The plant markers and garden signs in the Habitat Discovery Garden were done this way using scrap roofing material. The engraved gold charger recognizing Trena Sheppard at the bottom of the garden page was done on this machine as well.
Galvanized steel placards are ideal for outside applications.
My sister Lynn and her husband Art made painted wood blocks and personalized one for each student in both second grade classes at Burbank elementary to commemorate the move to the new Norwayne Elementary School.
My brother Tom is famous among family and friends for running a tight ship when he's in town visiting the farm. I couldn't help myself from creating the above which was posted just outside the entry to the kitchen.
The Habitat Restore is a major source of materials for this. The plaque for Tom was done using maple woodgrain flooring. Settings provided for burning through the surface layer. When insufficient contrast results, stain or acrylic paint can be worked in and wiped off the surface.
This medallion was made using plastic engraving stock with a gold surface appearance.
CerMark is a material that can be applied to glass, metal, ceramic and plastic to facilitate marking with a laser engraver. Dan Kaufman asked for help making an aluminum placard for his friend Rex Miller. Rex had customized a 1954 John Deere 70 tractor and the placard was for mounting on the battery box under the seat. Dan procured a piece of aluminum, sanded the surface and sprayed it with CerMark. He had previously laid out the design and converted it to a .pdf file. The laser engraver did the rest. Dan sprayed the finished item with a clear coat to protect the aluminum from oxidation.
1/16" thick plastic engraving stock was used to make the items below. On the left is a hanger for the engraved chargers, attached with double sticky foam. Center is a keyring. On the right is an inventory tag. Corel Draw, the drawing program used for much of the design work I do, has a barcode function.
The 13" diameter gold charger below can be engraved using the vector cutting mode of operation. These are often used to commemorate special events and can be signed using a permanent marker.
Aaron and Travis Arnold made cherry boxes and other items for Christmas presents and wanted them engraved.
A material that is frequently used on these laser engravers is 1/8" craft plywood. This material is relatively low cost and can be purchased at hobby stores like Pat Catan's, JoAnn Fabrics, and Hobby Lobby.
At the annual Santa's Workshop event in the Village of Creston, children are photographed with Santa, their pictures are printed and they leave with a framed photo. The frames are engraved in advance.
The laser engravers are valuable in supporting the local schools as well. In the example below, the snowflakes in the center are made by activity participants using beads and pipecleaners and are mounted into the commemorative stand. The stand is made from 1/8" acrylic. The material was mostly small pieces that were donated by WG Dairy, Wooster Glass and Hometown Hardware. The engraving and cutting took under 8 minutes each.
Customized pencils are popular. (It seems that many names used in recent years can't be found on the drug store name rack.) Twelve colors of pencils are kept in inventory.
Wayne College student Dusty Ball and his girlfriend Jennifer visited one evening and we gained some knowledge and skill engraving wine glasses.
Retired Norwayne High School teacher Aaron Arnold used the laser engravers to create recognition plaques for Smithville and Norwayne FFA chapters.
Mr. Oswald, the Norwayne
High School woodworking teacher, brought several students to get acquainted
with the laser engravers. Each fabricated a keyring and engraved a pencil
and an anodized aluminum notepad cover.
These are just a number of examples of what can be done using laser engravers. The limit is one's imagination.
