Revolved 3D Logo Sign

Your text and logo are laid out as one flat drawing. That drawing is lying on the bed and is revolved (swept round) about a horizontal line just in front of its bottom edge, by the angle you choose (75° by default). Each letter becomes a curved fin that starts flat on the bed and rises to a face showing the letter, tilted up towards you – so from the front it reads as your name and logo, and from above it looks like a row of curved blades.

The angle is how far the drawing is swept: 90° stands the letter faces upright, 45° leans them back and makes a lower, flatter sign, 30° is almost a relief. The axis offset moves the hinge line in front of the letters: at 0 the bottom of the lowest line is a sharp edge on the bed, a larger offset makes every fin thicker and deeper.

Usually not – print it as downloaded, base down. The outside of every fin faces upwards. The one place that overhangs is the roof of a gap that is closer to the front, such as the inside top of O, A and R, or the space between two parts of a logo: towards the top of the sweep that surface leans forward past 45° (up to the revolve angle). On text-sized letters it is short and prints like the curved-letter signs it imitates; for a large logo with big holes, or at angles near 90°, use tree supports from the build plate (the gaps are open down to the bed). A lower angle such as 45° avoids it almost entirely.

Keep the base on and download the ZIP: it has the base and the letters as separate STLs in the same position, plus a combined one. Load both on an AMS / MMU as one object, or use the combined STL with a filament change at the base thickness shown under the preview.

Yes. Upload a PNG, JPG or SVG; it is traced in your browser (threshold, invert, smoothing and detail work like in the Two-Colour Sign Maker). Bold, solid logos work best – very thin lines become very thin fins. Use logos you have the right to print.

Yes – tick “Pocket the front face for laser-cut acrylic”. The flat front face gets a pocket following every outline, leaving a printed border round each letter (and round the inside of O, A and R), as deep as your acrylic (or 0.2 mm less, so it stands slightly proud). Download the acrylic SVG or DXF: every piece is the pocket minus the fit gap, already compensated for your laser kerf, on a red CUT layer in millimetres. Shapes too narrow for a pocket, pockets that would break through the thin bottom of a fin, and acrylic narrower than 1 mm are flagged in red.

The 3D Sign Generator makes flat desk and door signs with straight extruded text, the Two-Colour Sign Maker makes flat two-layer badges, the Stamp and Stencil generators make stamps and cut-out stencils. This tool is the only one that revolves the design into curved, standing letters.
