Illustrations of custom-made equipment used for HIPE preparation and printing. (A) Setup used for HIPE emulsification. The helical stirrer blade and the lid were custom-made for 50 mL Falcon tubes. The lid offers an opening for the stirrer blade and a threaded hole to connect tubing and allow the continuous addition of aqueous phase using a syringe pump. (B) Cure-on-dispense setup used in combination with a Gesim BioScaffolder 3.1. Four high power UV LEDs (1) are attached to a metal heatsink (2) which is perfused by air from a fan (3) for active cooling. The mount (4) allows the direct attachment to 10 mL cartridges (5).
