8 μm diameter beads of poly(methyl methacrylate-co-ethylene glycol dimethacrylate) 5% cross-linked (Sigma-Aldrich) were added(30 vol%) to the powder/water mixture. CSP was performed by placing the mixture in the mold at rt and pressing at 500 MPa for 10 min. The mold was heated up to 150 °C (heating ramp 9 °C/min) and kept under the same conditions for 30 min. After CSP a debonding treatment was performed at 500 °C (heating ramp 50 °C/h).
