Art Sign Works Uses Precision Board for Its Custom Carved 3-D Bas-Relief Signs & Plaques
Art Sign Works Inc., founded in 2005, has been making 3-D bas-relief plaques from Precision Board since 2009. Previously, our team utilized HDU from two U.S. manufacturers but we determined that Precision Board., made by Coastal Enterprises in Orange County, California, was the highest quality material and was the best for carving. Here at ASW, we create about 10,000 signs and plaques each year; efficiency and quality are key to completing orders in a timely manner.
A majority of the signs and plaques we create are carved in 2.5-D, raised multi-level or engraved (incised) relief from Precision Board. We also design and fabricate over 1,500 3-D bas-relief plaques and signs. A large number of our 3-D orders are wall plaques that are for federal, state and local governments, law enforcement, and universities as well as businesses, churches and homes. Additionally, our plaques hang on walls in the White House, Air Force One, Congress, the Supreme Court, the Pentagon, and many state capitals. A few of our 3-D signs and plaques are shown below.
Examles of 3D Carved Plaques
3-D bas-relief plaques require considerably more machine time, along with additional hours of labor for carving and painting, than artwork carved in 2.5-D. About 1/3 of the products we make are carved in 3-D, and are very popular with government agencies, as well as police and sheriff’s departments. When plated with bronze, brass or aluminum, these carved HDU products are favored over solid metals because they cost only about one-third and weigh only a tenth as much. Plated products also make the installation of large plaques on walls much simpler.
Most of our 3-D plaques and signs are made out of PBLT-20 Precision Board HDU . This HDU is 20 lb/ft3, a much higher density than the 15 lb/ft3 density HDU other sign companies use, so it is 40% stronger and carves cleaner and more accurately. We also make about 20% of them from solid Mahogany, Maple, Cedar, Redwood and Oak woods. We paint or metal-plate the HDU plaques and signs, and typically stain the wood. Our 3-D HDU plaques and signs are typically half the price of our 3-D wood plaques, and they will not crack, split or rot, so they require less maintenance and last longer, making them more popular with our customers.
Examples of Carved 3D Bas and Half relief Signs and Plaques
Let’s take a look into the process of creating 3-D signs & plaques. We start off by developing a 2-D Adobe Illustrator vector rendering, similar to what we would make if it were 2.5-D. This defines the areas that need to be raised and lowered. One of our graphic designers then develops a custom 3-D geometric model from the 2-D rendering using 3-D graphic software such as Maya, Z-Brush, or Rhino. This siftware then generates an STL file that we can incorporate into our 3-D CNC router tool path control program called ASPIRE. The 3-D software modeling process can take anywhere from four (4) to twenty (20) hours, depending on size, detail and complexity. Once a new model is developed, the 3D geometric model can be scaled to any size and reused for subsequent projects with the same or very similar artwork.. To speed up the process, occasionally we purchase off-the-shelf STL files of animals, trees and man-made objects from commercial companies.
Next, we put a sheet of Precision Board, usually 5’ x 8’ or 5 ' x 10", 2” thick, on one of our six 5’ x 12’ Shopbot CNC routers.
Carved 3D HDU Coats of Arms
In order to ensure accuracy and attention to detail, the 3-D CNC routing requires ball-nose router bits as small as 1/16 inch in diameter (1/32 inch in diameter for very detailed artwork) to carve smooth routed surfaces. It can take from six to 36 hours to carve a single 3-D sign or plaque, depending on its size and detail. For a 3-D version, it takes 6-to-10 times as long as a 2.5-D, multi-level raised relief sign or plaque. We run our six CNC routers up to 16 hours a day, six days a week to keep up with our orders.
After routing, our craftsmen perform fine hand sanding of all of the front surfaces to remove any tool marks and, if background areas need to be sandblasted, this is when we’ll do that as well. It is then painted with a thick HDU primer to further smooth the surfaces, and the background color is added in our paint spray booth.
Next, the piece is moved to our finishing and fine paint shop, where our artists use brushes to paint the plaques in long-lasting vibrant colors. We exclusively use Matthews acrylic polyurethane automotive-grade (MAP) for background areas and 1-Shot paint for artwork, text and borders. It takes longer to paint a 3-D sign or plaque than one carved in 2.5-D relief because 3-D artwork must be painted with an artist brush due to its curved and rounded surfaces, whereas 2.5-D artwork has flat surfaces and can be painted with a mini-roller. All plaques and signs, both indoor and outdoor use, are then coated with two Matthews MAP semi-gloss or satin clear coats to protect against weather, UV radiation, oxidation, scratches and graffiti.
