◆ Sealing wax
A raised heart in a ring of dots: a 28 mm wax seal stamp for wedding invitations and love letters.
A heart in the middle of a 28 mm seal, framed by a ring of twelve dots and a fine border, the classic seal for anything sent with love. Seal wedding invitations, save-the-dates, Valentine's cards and anniversary letters, or the ribbon on a gift box.
Made with our free stamp maker, not modelled by hand: we drew the design in code, knocked out of a solid disc, uploaded the picture and set the circle shape to 28 mm across with the relief at 1 mm, enough for wax without trapping it. The page traced it into the face, so the design is cut into the stamp and stands proud on the seal. The zip holds exactly what the tool gives you: a stamp plate with a 1 mm raised face and a handle that screws into its back, as one STL, and as a 3MF with the face, plate and handle as separate coloured parts. The page mirrors the face, so the mark reads the right way round, and flares every raised wall a little toward the plate, which helps the stamp let go of warm sealing wax. The picture is in the zip too, so you can change it and make your own.
Shown as a 3D render of the printed stamp and the seal it presses into a puddle of wax, not a photo.
Print both parts as exported: the plate face down on the bed, the handle standing on its foot, no supports.
Screw the handle into the back of the plate until it is snug.
Chill the face on an ice pack for a minute.
Pour a puddle of wax a little wider than the seal, wait about ten seconds, then press the stamp straight down and hold it still for 10 to 20 seconds.
Lift straight up once the wax has set, and chill the stamp again before the next seal.

As many as you have wax for. Chill the stamp between seals, on an ice pack or a cold metal plate, and it keeps releasing cleanly. A batch of a hundred invitations is an evening with two stamps, one chilling while you use the other.
Deep red and burgundy are the classics, and blush pink, gold and ivory suit wedding stationery. Metallic waxes show the raised heart and the ring of dots best, because the light catches the edges.
PETG for the plate if you have it: it stays stiff to about 80 C, where PLA softens near 60 C, and a fresh puddle of sealing wax is hotter than that for a few seconds. PLA works too if you chill the plate between seals. Skip TPU: a soft face blurs the design.
