Raised, embossed or engraved:
which text prints best
Raised text (also called embossed) stands out of the surface, typically 0.6 to 1 mm. Engraved text (debossed, recessed or inset) is cut into it, typically 0.4 to 0.8 mm deep. Raised text is easier to print and to colour. Engraved text is better on parts you handle or slide against something.

The terms, in plain words
People use four or five names for two ideas. Here is what each one means for a 3D print.
Raised = embossed
The letters stand up from the surface, like a keychain with a name on a plate. In CAD, an emboss tool adds material. Most name tags, signs and plaques use this style.
Engraved = debossed = recessed = inset
The letters are cut into the surface, like writing carved into wood. Debossed comes from leather work, where letters are pressed in. For a print it all means the same: a letter-shaped pocket.
Flush or inlaid
The letters sit level with the surface and differ only in colour. On FDM this is usually done on the first layers, face down on the bed. It needs a multi-material printer.
Standalone letters
No surface at all: the letters are the part. Cake toppers and door letters work this way. See 3D printed letters for that case.
Depth and size that stay readable
Typical values for a 0.4 mm nozzle and 0.2 mm layers. The stroke column is the thinnest part of a letter, not its height.
| Style | Depth or height | Min. stroke width | Min. letter height | Notes |
|---|---|---|---|---|
| Raised, minimum | 0.4 mm (2 layers) | 0.8 mm | 5 mm bold | Enough for a colour change, hardly felt |
| Raised, standard | 0.6 to 1 mm | 0.8 mm | 5 to 8 mm | Keychains, tags, desk plates |
| Raised, tactile | 1.5 to 2 mm | 1 mm or more | 8 mm | Kids' tags, labels you read by touch |
| Engraved, shallow | 0.4 mm (2 layers) | 0.8 mm | 6 mm bold | Only readable with paint or a colour change |
| Engraved, standard | 0.6 to 0.8 mm | 0.8 to 1 mm | 6 to 8 mm | Tool labels, box lids, functional parts |
| Engraved, deep | 1 to 1.5 mm | 1.2 mm | 10 mm | Good for filling with epoxy; slow to fill with paint |
Engraved slots are harder than raised ridges: the walls on both sides of a narrow slot squeeze it shut. If an engraved letter is under about 0.6 mm wide, the slicer closes it.
Why raised text is the default
Raised text prints face up with no tricks. The plate goes down first, then the letters grow from it for a few layers. Every letter has a flat top that the nozzle draws cleanly, and the sides are straight walls. If you want the letters in a second colour, you change filament once, at the layer where the letters start. That is why almost every name keychain and door sign is built this way.
The limits: raised letters catch on things. On a phone case, a drawer front or a tool handle they wear down or snag. Tall thin letters on a raised design also wobble while printing, so keep the height at 1 to 2 times the stroke width. The text size guide has the numbers per nozzle.
When engraved text is the better choice
Engrave text when the surface has to stay smooth: box lids that stack, labels on parts that slide into a slot, handles, coasters and anything that goes in a pocket. Engraved text also survives wear, since there is nothing sticking out to break.
Engraved text is harder to read, because a pocket in the same colour has almost no contrast. Plan to fill it (paint, wax crayon, epoxy) or print the floor of the pocket in a second colour, which is explained below. A bold font matters even more here, since each slot must stay open against the walls around it.
Face up or face down: which prints cleaner
The side that touches the bed comes out flat and sharp, with the bed's texture. The top side shows the top layer pattern. Here is how each style behaves.
| Style | Face up (text on top) | Face down (text on the bed) |
|---|---|---|
| Raised text | Easy and reliable. Clean letter tops, straight sides. The standard way. | Letters print first, then the plate bridges over the gaps. The letters get the bed texture, but the plate underside sags between letters. |
| Engraved text | Fine. The pocket floor is a top surface, edges are clean. | Very crisp outline from the bed, mirror-reversed automatically. The layer above the pocket has to bridge each letter, fine for pockets under about 10 mm. |
| Flush inlay | Not practical. | Best result of all: the letters are part of the first layers, perfectly flat and sharp. Needs an AMS or MMU. |
On a textured PEI sheet, face-down text picks up the texture, which many people like on signs. On a smooth sheet it comes out glossy.
Two colours with each style
All three styles can be two-coloured on a single-nozzle printer, except flush inlay. The trick is always one filament change at the right height.
| Style | How to get coloured letters | Swaps | Where to swap |
|---|---|---|---|
| Raised, face up | Plate in colour A, letters in colour B | 1 | First layer of the letters |
| Engraved, face up | Print the bottom in colour B, the top in colour A. The pocket floor shows colour B. | 1 | The layer at the bottom of the pocket |
| Engraved, face down | First layers in colour A with letter holes, then colour B. Colour B shows through the holes. | 1 | First layer above the pocket |
| Flush inlay | Letters and surface share layers | Every layer | Needs an AMS or MMU |
The step-by-step for a filament change at a layer is in 3D print text in a different colour.
Making each style in common tools
- 1
Raised text on a plate: NameSTL
Pick the outline, keychain or pet tag base in the generator. The Thickness slider (0.5 to 10 mm) sets the letter height. The plate reaches 0.5 mm up into the letters, so they stand about Thickness minus 0.5 mm above it: set 1.5 mm for 1 mm raised text on a tag or sign. The 3MF assigns letters and plate to separate filament slots.

Raised or engraved on your own model: Bambu Studio or OrcaSlicer
Right-click the model and add text. Choose Part for raised text, Negative part for engraved text. See the full walkthrough in adding text in Bambu Studio.

Engrave NameSTL letters into another object
Download the letters with no base, load your object in the slicer, then right-click it and add the letters as a negative part (PrusaSlicer calls it a negative volume). Sink them 0.6 to 0.8 mm into the surface. A script font arrives as one joined word, which is easier to place than loose block letters.
- 4
CAD: Tinkercad or Fusion
In Tinkercad, set the text shape to Hole and group it with the body. In Fusion, the Emboss tool does both directions. More options in adding text to an STL.
What NameSTL makes, and what it doesn't
NameSTL builds raised text: letters on an outline plate, a keychain, a pet tag, a standing base or a circle, plus standalone letters with no base. It does not cut text into a surface. For engraved text, use the negative part trick above or your slicer's text tool.
Designing is free and needs no account. You pay when you download the STL or 3MF, as a single download or on the Unlimited plan.
Questions people ask
What is the difference between embossed and engraved text?
Embossed text is raised above the surface. Engraved (or debossed) text is cut into it. On a 3D print, raised text is usually 0.6 to 1 mm tall and engraved text 0.4 to 0.8 mm deep.
How deep should embossed text be on a 3D print?
0.6 to 1 mm for most tags and signs, which is three to five layers at 0.2 mm. 0.4 mm is the minimum if you only want a colour change. Go up to 1.5 or 2 mm for tactile labels with strokes of at least 1 mm.
How deep should engraved or debossed text be?
0.4 to 0.8 mm is typical. Deeper pockets are hard to fill with paint and collect stringing. Keep every slot at least 0.8 mm wide, or the walls on each side close it up.
Is raised or engraved text easier to 3D print?
Raised text. It prints face up with no bridges and takes a second colour with one filament change. Engraved text needs a bolder font and, without paint or a colour trick, is hard to read.
Can I print engraved text face down?
Yes, and the outline comes out very crisp because it forms against the bed. The slicer mirrors it for you when you flip the part. The layer above the pocket bridges each letter, which works for letters up to about 10 mm across.
What does recessed or inset text mean?
The same as engraved or debossed: the letters sit below the surface as pockets. Inset is sometimes also used for flush inlays, where letters of another colour fill the pocket level with the surface.
