The technical drawings for the prototype development of the static mixer were created using the AutoCAD software from Autodesk. The static mixer was 3D printed in stainless steel 1.4404 (316L/V4A) at the d3d Manufacturing GmbH (Baindt, Germany) using the selective laser melting (slm) process. Threads and sealing surfaces were machined afterwards. Steel capillaries with an outer diameter of 1/16″ and an inner diameter of 1.0 mm consisting of stainless steel 1.4404 (316L/V4A) were used, which were purchased from TECHLAB. PTFE tubing with an AD (1/4″) and ID (1/8″) was purchased from Bohlender and PEEK capillaries AD (1/16″) and ID (1.0 mm) from BGB and cut to the required lengths. All solutions were pumped with Fusion 4000 pumps from CHEMYX and high-pressure glass syringes from CETONI in volumes of 10, 25, 50 mL. Flow microreactor systems were dipped in individual bath to control the temperature. The syringe holders for the syringe pump were designed according to the requirements and 3D printed at JOMANTIK in Alumide.
