A formulation containing an increased amount of the stabilizer pyrogallol (0.5 wt% instead of 0.2 wt%) and a slightly increased amount of the photoinitiator TPO (1.5 mol% instead of 1 mol%) was printed into a challenging “additive manufacturing only” hollow pyramid shape with a 7 × 7 mm baseplate.

C Scanning electron microscope image of the area highlighted with a red rectangle in (B). 3D models of all printed parts are displayed in Supplementary Fig. 3.
