Which direction is the design built when selecting X+, Y+ or Z+ orientation?

• A. The design is built in the positive direction of the respective axis
• B. The design is built in the negative direction
• C. It builds in a random direction
• D. It depends on the printer brand

Answer: (A)

In 3D printing, the plus signs on the axes define positive directions in the printer’s coordinate system. When you select X+, Y+, or Z+ orientation, you’re telling the printer to build in the positive direction along that axis. For example, Z+ means the layers build upward away from the build plate, while X+ moves toward the positive X side and Y+ toward the positive Y side. The opposite directions (X-, Y-, Z-) would reverse that path, and the choice isn’t dictated by the brand of the printer but by the axis orientation defined in the slicer’s coordinate system.
