How to Prepare a Logo for Plasma Cutting
Plasma cutting metal with a logo design requires careful vector preparation. Use this step-by-step guide to convert any logo to a DXF file ready for Hypertherm ProNest, SheetCam, or any plasma CAM system.
About How to prepare logo for plasma cutting
Plasma cutting has unique geometry requirements compared to other cutting methods. The plasma arc has a kerf width — the amount of material consumed during cutting. For fine logo details, this kerf width destroys narrow features and small enclosed areas. Good preparation compensates for these physical constraints.
Step 1 — Vectorize the logo If the logo exists as a PNG or JPG, upload it to the Logo Vectorizer and download the SVG. If the logo is already in SVG or AI format, proceed directly to step 2.
Step 2 — Analyze feature sizes Open the SVG in Inkscape. Consider the intended cut size. Calculate the minimum feature size at that scale. For a typical plasma cutter on 3mm steel, kerf is around 1–2mm. Any feature smaller than 3–4mm at cut size will be degraded or destroyed.
Step 3 — Simplify and redesign for plasma — Remove interior islands that are too small to hold after cutting (they fall through or vibrate loose). — Stencilize enclosed letters — connect interior cutouts to the outer boundary with small bridges. — Simplify complex path curves using Path > Simplify in Inkscape. — Remove all thin strokes and fine details that are below the minimum feature size.
Step 4 — Export to DXF File > Save As > DXF format in Inkscape. Import the DXF into SheetCam, ProNest, or FastCAM for lead-in/lead-out generation and nesting.
Step 5 — Test on scrap material before final cutting.
