3D Print Simulator

A friendlier daily limit on the 3D print tools.

• Building and previewing is now free. Try settings, spin the model and see the result on any tool as much as you like — your 3 free daily credits are only used when you save (download) an STL.
• Calibration & test prints are completely free. Temperature towers, tolerance gauges and the rest never use a credit.

A different kind of print — the printer stops halfway, you lay tulle or organza in, and it carries on over the top.

• New: Print on Fabric. Lace wedding invitations, place cards and RSVPs printed straight onto tulle, organza or chiffon — the laser-cut look without a laser cutter.
• It writes the pause for you. Download G-code with the stop already inserted at exactly the right height, so the printer parks and waits while you lay the fabric.
• Five lace patterns built in — scrolling vine, scattered blossom, filigree border, damask medallion and art deco — all adjustable, plus six ready-made examples to start from.
• Add names, a date or a monogram, or bring your own artwork. Card sizes from place card to DL, or set your own.
• Floating leaves and petals are fine here — the fabric is what holds them, which is exactly why this technique gives that delicate look.

Tune your printer properly — every model sized to your machine and labelled so you can read it.

• New: Calibration & Test Prints. Seventeen tuning models — temperature tower, retraction, tolerance gauge, overhangs, bridging, first layer, hole sizes, thin walls, support gaps and more.
• Everything is adjustable. Set the sizes, ranges and steps to suit your printer and your filament instead of printing someone else's numbers.
• The values are printed on the models. No more counting bands to work out which floor was 210 °C.
• Each one tells you how to read it — what a good result looks like, what a bad one means, and which setting to change.
• They generate instantly in your browser and preview as you type.

Put a name or logo onto a model you already have.

• New: Engrave & Emboss. Load any STL, drop text or a picture onto it, and cut it in or raise it out.
• Drag it into place on an outline of your own model, seen from whichever side you are working on.
• The depth stays even on curved surfaces. 0.8 mm deep means 0.8 mm on a cylinder or a sphere, not just on a flat panel.
• The artwork only lands on the face you chose — it will not come through mirrored on the back.

Type a name, get a printable sign — in any font on your computer.

• New: Text to STL. Name plates, door signs, keyring tags, fridge magnets and spray stencils, straight from typed text.
• Every font on your machine, not a fixed list — bold, italic, letter spacing, multiple lines and alignment all included.
• It tells you when the letters are too thin to print and shows exactly which bits would vanish, in red, before you waste an hour finding out.
• Hanging holes for keyrings and hooks — the plate grows to make room, so your border stays exactly as you set it.
• Sizes are measured on the letters themselves, so 20 mm tall means 20 mm tall whichever font you pick.
