PLASTICS 3D PRINTING – EMBRACE RAPID MANUFACTURING
One of the rewards of the 3D printing revolution is the ability to begin production without the delay and expense of tooling, and to produce customized, geometrically complex products free from traditional manufacturing constraints.
Now you can realize revenue without time-consuming inventory management. With in-house, on-demand production, inventory becomes a digital file at your fingertips.
3D printing end-product components
Stratasys Production Series 3D Printers build the most durable, stable, repeatable parts in the industry. With accuracy that rivals injection molding and an array of real thermoplastic materials, Stratasys helps manufacturers say yes to more opportunities in low-volume, customized production parts and factory automation.
Designers and manufacturing engineers are free to optimize parts with organic shapes and complex geometries, including hollow interiors and negative draft. Traditional tooling constraints don’t apply in the world of 3D printing. Now you make the rules.
METALS 3D PRINTING – SLM – NEW SOLUTIONS FOR THE PROCESS INDUSTRY
Additive Manufacturing and especially 3D printing are regarded as “game changer“ for many industries. How big is the potential really for the apparatus and plant in the process industry and what challenges lie ahead will be shown by the example of a newly developed high-pressure reactor of THALETEC.
High pressure reactors are used in process engineering for carrying out chemical reactions under pressures up to 200 bar. So far, these reactors are machined manufactured from materials such as stainless steel or Hastelloy. For use in chemically highly aggressive products high pressure reactors are also equipped with a liner made of PTFE.
THALETEC has developed for this application, the prototype of a glass-lined high-pressure reactor (Figure 1). This new solution was prepared using the additive, metal-based manufacturing process, the „Selective Laser Melting“ (SLM). The use of this manufacturing process opens the way to carry out the high-pressure reactor with an integrated temperature control channel for the heating or cooling of the reactor interior.
The combination of enamel and integrated temperature control channel provides over previously available solutions significantly improved heat transfer between the product and temperature control and thus the opportunity to influence the heat effect of the process better. Moreover, a higher pressure holding ability is possible despite lower wall thicknesses and achieved a guaranteed non-diffusive and chemically highly resistant coating in the wetted interior. Further, the weight of the high-pressure reactor is reduced, which is in the handling of the reactors in the laboratory of importance.
By the SLM method it is possible to produce inner structures such as ducts and voids in complex components which cannot be produced by conventional machining manufacturing processes such as turning, milling and drilling. When using the SLM process the component is developed in the 3D CAD system and geometrically optimized, first the component will be processed digitally and then supplied to the SLM machine There in the component is built up in layers. The metal powder used by THALETEC for Selective Laser Melting can be glass-lined.
In order to use high-pressure reactors, they must according to Pressure Equipment Directive 97/23 (PED) and must be designed and executed for a valid set of rules, for example AD 2000. In close cooperation with a notified body additively manufactured high-pressure reactors of THALETEC can be produced according to the approved pressure equipment. THALETEC has a tested and proven approach that makes it possible to certify pressure equipment additively manufactured according to PED.
