Learn · The step nobody explains

You downloaded your file. Now what?

Every Designer Bee project ends with a file: an SVG for laser cutting or an STLfor 3D printing. That file doesn't go straight to the machine — it makes one quick stop in the machine's own (free) software first. Here's that step, in plain language, for both kinds of machine.

If you downloaded an SVG (laser cutting)

1. Open it in your laser software

Import the SVG into whatever program drives your laser: LightBurn (most hobby lasers), the Glowforge app, xTool Creative Space, or LaserGRBL. The design arrives at real size — Designer Bee exports use true millimeter units, so a 200 mm clock face is exactly 200 mm on the bed.

2. Check the two layers

The file carries exactly two colors, and your software reads them as two jobs: red lines are cuts (the laser goes all the way through) and black or blue areas are engraves (the laser marks the surface). Most programs assign these automatically — you just confirm cut is set to cut and engrave to engrave.

3. Set your material

3 mm plywood or MDFis the beginner sweet spot for every Designer Bee laser project. Pick it in your software's material list (or use your machine's recommended speed/power chart). If the fit of joints matters — the finger-joint box, the bird house — make sure the material thickness you cut matches the thickness you set in the tool.

4. Place, focus, run

Put your material on the bed, focus the laser, and run the job — engrave first, cut last (your software orders this for you). Stay with the machine while it runs; that's laser rule number one.

If you downloaded an STL (3D printing)

1. Open it in your slicer

A slicer is the free program that turns a 3D model into printer instructions: Bambu Studio, Cura, PrusaSlicer, or OrcaSlicer — whichever came with (or matches) your printer. Drag the STL in and it appears on a virtual print bed at real size.

2. Pick your material

Plain PLA is all a beginner needs — cheap, forgiving, and it works for every Designer Bee project. One special case: print lithophanes in white or natural PLA so light can shine through the thin areas.

3. Slice with default settings

The default profile (usually 0.2 mm layers) is fine for everything here. Lithophanes look sharpest at 0.1–0.15 mm layers and 100% infill. None of the projects need supports — anything that needed them has snap-off supports already baked into the file.

4. Print, and watch the first layer

Send the job and stay for the first layer. If it goes down smooth and stuck, the print almost always finishes well. If it doesn't stick, clean the bed with dish soap and water — that one habit fixes most beginner failures.

Don't have a machine? You still have this covered

Hundreds of US public libraries run free makerspaces with laser cutters and 3D printers — walk in with a library card and your file on a USB stick, and staff will help you run the machine. That's exactly what our makerspace map is for. The librarians there handle the software step with beginners every day.

If something looks wrong

• The design imports tiny or huge: tell your laser software the file uses millimeters (an import-dialog setting, usually remembered after the first time).
• Everything cuts, nothing engraves: the color-to-operation mapping got lost — re-assign red to cut and black/blue to engrave in the layers panel.
• Joints too tight or loose: your material's real thickness differs from the tool setting — measure it and re-export.
• Print looks stringy or rough: lower the nozzle temperature 5 degrees, and make sure the filament is dry.
