CNC routed sign making refers to using a computer-controlled router to cut, carve, and profile sign blanks from wood, HDU foam, PVC, acrylic, or composite panels. The process produces crisp letterforms, dimensional logos, v-carved text, and routed backgrounds that are difficult or impossible to achieve by hand. CNC routed signs are common in retail, hospitality, wayfinding, and architectural applications where dimensional lettering or carved detail is required at consistent quality across single units or production runs. ### What materials work best for CNC routed signs? HDU (high-density urethane) foam is the most popular sign material. It routes cleanly, does not absorb moisture, and paints beautifully. PVC foam board (Sintra) is a lower-cost option for interior signs. Hardwoods like oak, maple, and walnut produce rich grain texture for dimensional carved signs. MDF is ideal for painted interior signs where cost matters. Acrylic and aluminum composite (like Dibond) work well for modern flat-cut letters and backlit panels. Material choice depends on your installation environment, finish, and budget. ### How deep can you carve or engrave into sign material? Carve depth depends on material and bit type. In HDU foam, we can carve up to 2 inches deep in a single setup. In hardwood and MDF, v-carve depths of 0.25 to 0.75 inches are standard for clean lettering. Pocket carving for recessed backgrounds is typically 0.125 to 0.5 inches deep. Deeper cuts require multiple passes and add to cutting time and cost. Include your target carve depth when submitting your project at openspindle.com/quote so we can confirm tooling compatibility and pricing. ### What file formats should I use for a CNC routed sign? Vector files are required. DXF, DWG, SVG, or AI formats all work well. Text should be converted to outlines or curves before submitting so font rendering is exact. For v-carve and 3D relief work, STL or OBJ files are accepted. If you have a logo or artwork only as a raster image (PNG, JPG), our team can vectorize it for a setup fee. Always submit at 1:1 scale with separate layers for cut lines, carve paths, and drill holes if applicable. ### Can you cut dimensional letters and logos for mounted signs? Yes. We cut individual dimensional letters and logo shapes from HDU, PVC, acrylic, hardwood, and aluminum composite that can be mounted directly to a wall, backer panel, or sign substrate. Letters are cut with a flat back or can be profiled with a beveled or rounded edge. We can drill mounting holes or route a channel on the back for standoff hardware. Minimum letter height for clean routing depends on material but is generally 1 inch or larger for interior detail.

A simple flat-cut acrylic or PVC sign panel starts around $40-$80 for a single piece under 2 square feet, not including material. HDU carved signs with v-carved text and painted backgrounds range from $80-$200 or more depending on size, detail, and carve depth. Dimensional letter sets for a business name are typically priced per letter, starting around $8-$20 per character depending on height and material. Custom shapes, complex relief carving, and multi-layer builds increase cost. Submit your project at openspindle.com/quote with your artwork for an accurate estimate. ### What is v-carving and when should I use it for my sign? V-carving is a CNC routing technique that uses a V-shaped bit to cut tapered grooves that follow the outlines of letters or artwork. The result is a chiseled, hand-carved look that is especially striking in wood and HDU. V-carving works best on letters 0.5 inches tall or larger and produces clean, sharp results on both serif and sans-serif fonts. It is a popular choice for wooden business signs, address plaques, and decorative panels where a traditional crafted aesthetic is desired.

We offer sanding and surface prep to get signs paint-ready, but in-house painting and finishing are not currently available. Parts are delivered clean, sanded, and ready for your paint or coating process. HDU and PVC signs accept acrylic and latex paints directly. Hardwood signs benefit from a sealer coat before painting or staining. If you need a turnkey finished sign, we recommend pairing our cut parts with a local sign painter or finishing shop. We are happy to advise on prep steps for your chosen finish. ### What is the minimum letter size you can CNC rout cleanly? Minimum letter size depends on font style and material. For clean interior detail on standard fonts, 0.75 to 1 inch tall letters are the practical minimum in HDU and MDF. Condensed or script fonts with tight strokes may require 1.5 inches or larger for clean results. Acrylic and aluminum composite can hold slightly finer detail due to material rigidity. If your design includes small text, share the file before ordering at openspindle.com/quote and we will confirm whether the detail can be achieved cleanly at the requested size. ### How do I get a quote for a CNC routed sign? Submit your project at openspindle.com/quote. Upload your vector artwork (DXF, DWG, SVG, or AI) along with your material preference, sign dimensions, quantity, and any notes on carve depth or finish. You will receive a line-item quote within one business day. If your artwork is not finalized, a rough sketch or description is enough to get a ballpark estimate. For custom dimensional letter sets or large architectural sign projects, reach out directly to discuss scope and lead time.
