Which slicers can open the files?
STEP files open in Bambu Studio, PrusaSlicer (2.5 and later), OrcaSlicer and most CAD apps. 3MF and STL files open everywhere.
Do I need an account or internet connection?
No. Lets3dPrint works offline and has no account. Purchases use your Apple Account through the App Store.
What is free and what needs Pro?
All modelling, the parts library, smart objects, Data to 3D, Flow Lines, saving and opening are free. Exporting STEP, 3MF and STL files, Print Check, keeping textures and surface waves (their preview is free) and running scripts need Lets3dPrint Pro, monthly or yearly, each with a free first week.
Are textures in the files I export?
Yes, in STL and 3MF: the textured surface is what your slicer gets, and Print Check measures it. STEP keeps the exact solid without the texture, since STEP describes exact shapes, not relief.
What is a smart object?
A part with its own steps and values that you keep in the project and place many times: at points, in a grid or spread over a face. Each placement can set the values, and a formula can work them out from where each copy stands. Edit the object and every copy changes. Make one from a library part (Make Smart Object) or from the script panel.
Which tables can Data to 3D read?
CSV, TSV and text with semicolons or spaces between the numbers. A first row of headings and a first column of labels are recognised and left out; decimal commas work with semicolons and tabs. Three columns of numbers (x, y, value) can become columns standing at x and y.
Can I print a map or a terrain?
Yes. Generate → Import Map opens an image, a GeoTIFF, an SRTM .hgt tile, an .asc grid or SVG contour lines and makes a relief from it, on a base, as a thin wall or round a globe. Create → Generate Map makes a landscape from a seed. Real heights look flat at map scale, so use exaggeration, or set the height in millimetres.
Can I make a lampshade or a vase?
Yes. Generate → Flow Lines opens a lattice shade at once; choose Twisted Vase, Wavy Lines or Braid, or type your own profile and path. The lines and the rims print as one solid with a flat bottom. Pick a flat face first and the lines stand on it, joined to that part.
My part is bigger than my printer. What now?
Draw the cut lines in a sketch across the part, then choose Split → Sketch curve or Whole sketch. The pieces get jigsaw or dovetail locks with clearance for your printer (0.15 mm a side by default), so they slide together after printing.
Is there an iPad version?
The Mac app comes first. The app is built to run on iPad too, and an iPad release is planned.
How do I cancel a subscription?
Open the App Store, click your name, then Account Settings → Subscriptions. You keep Pro until the end of the period you paid for.
A tool I need is missing. Can I ask for it?
Yes, please. Request a feature and tell us what you want to print. In the app it is under Help → Request a Feature… and in Settings.
I bought Pro on another Mac. How do I get it here?
Open Lets3dPrint → Settings → Pro and click Restore Purchases, signed in with the same Apple Account.
