AUGUST 2017 Additive Manufacturing TECH REVIEW 42 Automated Washing and Post-Curing Systems Enhance Mechanical Properties of 3D Prints Form Wash and Form Cure from Formlabs is a complete system for automated washing and post-curing intend- ed to bring Formlabs materials to maximum mechanical properties. Built to complete the stereolithography (SLA) experience, Form Wash and Form Cure are said to streamline the entire 3D printing process to produce more consistent results with less time and effort. Users can place the Form 2's build platform or 3D-printed parts directly into Form Wash, set the time and walk away, the company says. The system's impeller agitates parts in isopropyl alcohol to prepare them for post-curing. Form Cure pairs 405-nm light with a heating system that achieves tempera- ture conditions ideal for the properties of the SLA printed parts, Formlabs says. Dual Cleaning Process System Suitable for 3D-Printed Prototypes The Omegasonics 1900BTX combines two cleaning technol- ogies, a water agitation cleaning process and ultrasonic cavitation. Each process operates independently to facili- tate a faster, more thorough cleaning process with less labor that is especially effective for 3D-printed prototype parts. The new magnetic drive pump system in the 1900BTX allows for agitation with controlled turbulence so parts are not damaged. Inside the tank, the part flows circularly, helping dissolve the temporary support structure around the part. The flow and heat are both adjustable, as different materials require different pressures and temperatures. In addition, the water agitation tank features a directional spray nozzle, letting the user spray parts directly and precisely. The ultrasonic cleaning process generates cavitation energy inside the bath, creating internal pressure that dissolves the support structure for the parts. It utilizes a non-hazmat cleaning detergent that speeds up the process of removing delicate support material. OPM250L Metal 3D Printer One Stop Manufacturing Solution Parallel Mode 45,000 RPM Milling Conformal Cooling Quality Surface Finish Exclusive Sodick technology enables the OPM to sinter multiple parts simultaneously without loss in quality or added cost. The OPM hybrid 3D Printer comes equipped with a high speed mill integrated into the machine for finishing parts in-process. 3D Printed cooling channels can improve plastic mold productivity by 30-50%, revolutionizing throughput. With 99.99% density and finish milling capabilities, OPM parts have achieved surfaces as low as 0.22┬ÁmRa. Sodick's OPM line of hybrid Metal 3D Printers is made to achieve a toolmaker's precision. Moreover, only Sodick provides a one stop solution, selling EDM, Mills, and Plastic Injection Molding equipment alongside printers (847) 310-9000
