Convert a photo to a printable STL in the browser, then handle the orientation, supports and layer height that a lithophane needs in Bambu Studio.
Convert an image to STLYou have a photo, a logo, or a silhouette you want as a physical object, and you own a Bambu Lab printer. The gap between those two facts is a mesh file. The image to STL Bambu path is straightforward: convert the bitmap to geometry in the browser, save the STL, then open Bambu Studio and let it do what it does well. Nothing needs installing for the first half. PNG, JPG, WebP, HEIC and SVG all work, up to 20MB.
Where people get stuck is not the conversion itself but what comes out of it. A photo is a grid of brightness values with no thickness. Turning that into a solid means deciding a base height, a maximum relief height, and whether the back stays flat. Choose badly and you get a mesh that is paper thin at the highlights, which Bambu Studio will slice into a part that snaps when you flex it. Fix the numbers before you slice, not after.
Bambu Studio handles orientation, supports and plate placement with more automation than most slicers, which is helpful and also a way to get surprised. Auto-orient will lay an object flat on its largest face, and for a lithophane that is wrong in a specific way: you want the relief facing the light, standing vertical, with the flat back toward the viewer. Check the preview layer by layer before you send the file, especially on an A1 or P1 where the plate moves.
Most Bambu Lab owners arrive wanting one of these three objects.
Convert a portrait or landscape photo into a thin panel whose thickness varies with brightness. Print it standing vertical, at 0.08 to 0.12 mm layers, and backlight it in a frame. This is what most people mean by photo to 3D print on a Bambu Lab machine.
High-contrast artwork converts into a raised plaque: a flat base with the logo standing proud of it. Keep the base at 2 to 3 mm and the relief under 2 mm. A flat back means no supports when you print it face up.
A single-colour silhouette, a keychain outline, a shape you want to trace. Convert the outline and give the base enough thickness to hold its shape at 0.2 mm layers. Fast prints with few failure modes.
The lithophane is the workflow with the most ways to go wrong, so walk it in order.
Crop to the frame's aspect ratio, convert to grayscale, and lift the shadows so dark areas still carry detail. A photo with pure blacks prints as one flat slab of maximum thickness. Do this editing now, not in the slicer.
Upload the file, pick the relief mode, and set the two numbers that matter: minimum and maximum thickness. A working pair for PLA on a 0.4 mm nozzle is 0.8 mm at the thinnest point and 3.2 mm at the thickest. Download the STL.
Drag the STL onto the plate, or use File then Import. Open the object list and read the dimensions in millimetres. Get the size right here. Scaling in the print dialog just multiplies coordinates, it does not resample anything.
Stand the panel up with the relief facing the front of the plate, and rotate it so the long edge runs along Y. On a bed-slinger like the A1, that keeps plate motion from rocking the part. A 2 mm brim helps a tall panel stay put.
Set layer height to 0.08 or 0.12 mm, walls to 3 or 4, and infill to 100 percent, because a lithophane is read through its full thickness. Drop the outer wall speed to around 30 mm/s. Preview the layers before you send the file.
Six checks that catch most failed conversions before the first layer goes down.
Upload a JPG, PNG, WebP, HEIC, SVG, GIF, BMP or TIFF up to 20MB and get an STL back in the browser. No account, no install, and the upload clears from the cache afterwards.
Yes. Convert the photo to an STL first, then import that STL into Bambu Studio and slice it. The printer only ever sees geometry, so the print quality depends on the mesh you feed it and the layer height you choose.
