You type a name in a lovely script font, convert it to outlines, send it to the laser, and lift the sheet to find the name in three or four pieces. Script letters are drawn to look joined. In the font file each letter is still its own shape, and "looks joined" is not "is joined". This guide explains why names fall apart, which fonts survive cutting, and the five steps that make a name cut as one piece.

Why script names fall apart

Three separate things go wrong, and they need different fixes.

Letters touch but do not overlap. A script font's connecting strokes are designed to meet the next letter at the edge. On screen they look continuous. To the laser, two outlines that only touch are two cut paths running side by side. They either burn a gap between the letters or cut the same line twice.
Letters overlap but were never welded. Overlap is good. But if each letter is still a separate outline, the laser cuts every outline in full, including the parts hidden inside the neighbouring letter. The joint is cut straight through.
Strokes are thinner than the material can hold. Hairline scripts have strokes well under a millimetre at name size. The beam removes material (the kerf) on both sides of every line, and wood or acrylic that thin snaps, burns away or warps.

Here is one name, measured from the real outlines of an open-licence script font, at 100 mm wide:

The name Marsha in a script font: as typed it splits into four pieces (M, ar, s, ha); with the letters nudged 4% closer and welded it is two pieces; with a 0.3 mm outward offset it is one piece — As typed, "Marsha" comes off the bed as M, ar, s and ha. Tightening and welding gets it to two pieces, and a 0.3 mm offset joins the last gap.

Nothing about the first version looks wrong on screen. That is the whole problem, and it is why a check before cutting pays for itself.

What makes a script font laser-friendly

There is no single best font for cutting names, because size and material change the answer. These are the properties to look for:

Connecting strokes that overlap the next letter, not just meet it. Type a test word with many joins ("minimum" is a good one) and zoom in on the joins.
An even, fairly heavy stroke. Monoline or brush scripts survive. Calligraphic scripts with hairline upstrokes do not, at least not at ornament or cake-topper size.
Open counters. The holes inside a, e, o and g must stay open after the kerf. Small, tight counters fill in and the letter turns into a blob.
A moderate slant. Steep slants make long, thin overlaps that leave slivers and sharp spikes.
A licence that covers what you sell. Many free fonts are personal-use only. The SIL Open Font License allows selling items and cut files made with the font, but not the font itself.

The picture below compares a hairline script with a heavy brush script, both 90 mm wide. Everything in red is narrower than 1.5 mm.

The name Hazel in Great Vibes with a third of its area marked red as thinner than 1.5 mm, next to Hazel in Pacifico with none marked — Great Vibes and Pacifico, both open-licence fonts. About a third of the hairline script is under 1.5 mm; the brush script has none.

A heavy font is not automatically safe, though. In Mộc's own font trials for its name ornament files, Pacifico was set aside because its small counters filled in at ornament size. Heavy strokes and open counters pull in opposite directions, so test the font at the size you sell.

Five steps to a name that cuts in one piece

These steps work in any vector or laser program that can convert text to outlines and combine shapes. The menu names differ; the ideas do not.

1. Set the real size first

Set the name to its final width in millimetres before judging anything. A font that is fine at 200 mm can fall apart at 60 mm. Write the size down in your listing so buyers know what fits, and decide on a minimum letter height. Mộc's free generator refuses any name whose lowercase letters would come out shorter than 6 mm, as a cautious starting point for 3 mm wood.

2. Tighten the letter spacing until every join overlaps

Reduce the spacing (tracking) a few percent at a time until each connecting stroke runs into the next letter, not just up to it. In the "Marsha" example, 4% tighter closed two of the three gaps. Some letter pairs, often a capital followed by a lowercase letter, still will not reach. Nudge those by hand or add a short connecting stroke.

3. Convert to outlines and weld

Convert the text to paths or outlines, then use your software's weld, union or combine command so the letters become one shape. Check the result. Count the outlines: a welded name in one piece has one outer outline plus the holes inside letters. If your software lists objects, a name that still shows as five objects is not welded.

4. Thicken thin strokes, then close the slits

Offset the welded outline outward by 0.2 to 0.5 mm. This joins near-misses and fattens hairlines. It also has two side effects that you must check:

Counters shrink, and small ones can close completely.
Places where two strokes nearly touch become narrow slits that the laser cannot cut cleanly.

In the welded "Marsha", the checker found three slits under 1 mm around the final "a", where its strokes nearly meet. A small closing step (offset out by 0.6 mm, then back in by 0.6 mm) filled them without changing the letter shapes.

5. Give loose parts somewhere to hold on

Dots on i and j, accents, apostrophes and the second half of some capital letters are separate pieces by design. You have three options:

Join them to the letter below with a small bridge.
Stand the whole name on a bar or a frame so that every piece touches wood.
Engrave the dots instead of cutting them out.

The name ornament below uses the second option. Each letter, including both i dots, is tied to the bar it stands on.

Name ornament preview for Olivia in a rounded font: the name stands on a bar across the bauble, i dots tied to the letters, laser check reports ready to cut — Mộc's free Name Ornament Generator with a made-up name: dots tied, name on a bar, 13 of 13 checks passed. The same name in the script font on the narrow tag frame was refused, because the "v" would lose its shape at 9.5 mm.

Check the file before you cut

Looking at a name on screen will not show you a cut straight through a joint. A geometry check does. Here are the two "Marsha" files run through Mộc's free Laser SVG Checker, which runs in your browser and does not upload the file. A small hanging tab was added to both so that only the name itself is being judged.

Laser SVG Checker result for the unwelded name: 4 issues found, double or touching cuts, the part falls apart into 4 regions, bridge too thin at 1.2 mm, slits under 1 mm — As typed: crossing cut lines at the joins, the part falls apart into 4 regions, a 1.2 mm bridge, two slits.

Laser SVG Checker result for the welded, thickened name: ready to cut, 0 errors, 13 checks passed — Welded, offset 0.3 mm and slits closed: one piece, narrowest bridge 1.53 mm, ready to cut.

The checker uses 1.5 mm as its default minimum bridge, which suits 3 mm plywood. Treat any limit as a starting point. Kerf, focus and material vary between machines, so cut one test name on a scrap before a full sheet. A speed and power test card takes the guessing out of the settings.

Printable checklist

Open the image full size and print it, or copy the list into your workflow notes.

☐ Name set to its final width, in millimetres
☐ Lowercase letters tall enough for the material (start around 6 mm for 3 mm wood)
☐ Every connecting stroke overlaps the next letter (zoom in on each join)
☐ Converted to outlines, then welded into one shape
☐ One outer outline left, plus the holes inside letters
☐ Offset 0.2–0.5 mm outward where strokes are thin
☐ Counters still open; slits closed
☐ Dots, accents and apostrophes bridged, on a bar, or engraved
☐ File checked: no double cuts, one piece, bridges and holes above your limits
☐ One test cut on scrap before the full sheet

When you cut a lot of names

Doing this by hand is fine for a few orders a day. In the weeks before Christmas, or with a 120-guest wedding order, welding each name by hand becomes the bottleneck. Two things help. Pick fonts that pass the checks at your sizes with no hand fixes at all, and batch the work as described in how to batch personalized name orders. If you sell on Etsy, Mộc Laser Shop is one option: it welds and checks every name from your order export, and it is free for small runs.

FAQ

What font is best for laser cutting names?

One whose letters overlap at every join, with an even, fairly heavy stroke and open counters at the size you sell. Brush and monoline scripts usually beat calligraphic ones. Test your own longest and trickiest names at real size, and check the licence covers selling what you make.

Why do the letters of my name come out separately?

The letters were cut as separate outlines. Either they only touched, or they overlapped but were never welded into one shape. Tighten the spacing until they overlap, convert to outlines, then weld or union them.

What is the difference between welding and grouping?

Grouping keeps every letter a separate shape that moves together; the laser still cuts every outline. Welding merges them into one outline and deletes the lines inside the overlaps.

How thin can a letter stroke be?

It depends on the material, the kerf and the size of the piece. Mộc's checker uses 1.5 mm for 3 mm plywood as its default. Go wider for small pieces that get handled a lot, such as cake toppers, and cut a test before you promise a size in a listing.

What do I do with the dot on an i?

Bridge it to the letter, stand the name on a bar that touches every letter, or engrave the dot instead of cutting it. A loose dot falls through the honeycomb, or worse, tips up into the head.

Can I weld text and keep it editable?

Usually not: welding converts text to a shape. Keep an unwelded copy on a hidden layer, or keep the name in a list and rebuild it, so a typo fix does not mean redrawing the joins.
