Parametric Spiral Lampshade in Fusion: Revolve Intersect, Mirror, Circular Pattern

Learn how to model a spiral, lattice-style lampshade in Autodesk Fusion (Fusion 360) using Surface Tools and a clean parametric workflow that is ready for 3D printing. You will set up offset construction planes, build a twisted surface loft, thicken it for printability, then use Revolve with Intersect to carve the final form. After that, you will mirror and circular-pattern the bodies to create the repeating spiral look, and finish by lofting a stronger top and bottom rim.

This tutorial is ideal if you want a customizable, 3D printed lampshade design where you can easily tweak height, twist angle, wall thickness, and pattern density.

Chapters

00:00 Intro: spiral lampshade for 3D printing with Surface Tools
00:14 Create offset planes for bottom reference, height, and top reference
00:57 Top reference setup and sketch basics
01:02 Sketch guide lines and set the 60 degree twist angle
01:50 Surface Loft between lines to create the thin twisted surface
02:06 Thicken the surface to a printable wall thickness (2 mm total)
02:24 Sketch the lampshade profile with a spline and offset it (2 mm)
03:15 Revolve with Intersect to keep the thin spiral segment
03:41 Split Body using top and bottom planes, then remove extra bodies
04:23 Mirror the body to create the paired spiral element
04:42 Circular Pattern (bodies) around the center axis for the lattice
05:11 Decide on pattern density (example: 50 instances)
05:29 Build the top rim: project edge, circles, offset, and loft as Join
06:43 Cut the inner void at the top using a second loft
07:41 Repeat the rim process on the bottom (loft Join, then loft Cut)
09:06 Final result: fully joined, parametric spiral lampshade ready to print

Key parameters shown in the video

Lampshade height plane: 200 mm
Twist angle: 60 degrees
Thicken: 1 mm per side (2 mm total)
Circular pattern example: 50 instances
Rim offsets: negative 3 mm (for added strength)

3D printing note:
Use an LED bulb to reduce heat, and choose a material suitable for your lamp environment. Test fit your socket hardware before printing the final version.

If you build your own variation, share what you changed (height, twist angle, number of pattern instances, rim thickness) and how it printed.
