3D printing for 3D printer

The new HP Multi Jet Fusion 5200 3D printer can be seamlessly integrated into the Digital Enterprise solutions from Siemens. The 3D printer is living proof that additive manufacturing can be used to market products quickly and produce flexibly, sustainably, and in large unit quantities.

This 3D printer can print its own parts – and improve its performance in the process. The new HP Multi Jet Fusion 5200 is evidence of how industry can benefit from 3D printing – if it’s seamlessly integrated into the Digital Enterprise.

 

This flexibility is especially beneficial in the automotive industry. Larger unit quantities can be manufactured just as easily as one-off products like individual wheel trims. The result: a happy customer!

Integration makes for a more efficient manufacturing processes

The solution from Siemens and HP integrates hardware, software, data intelligence, and services, making the entire manufacturing process more efficient. The combination of digital twins for product, production, and performance with the MindSphere cloud solution enables automotive and industrial customers to create high-quality, mid-volume, 3D-printed parts faster, with unique product designs, for new applications, and in digital factories.

Speed is also a key attribute of the HP Multi Jet Fusion 5200. It’s therefore vital to keep the print head at the right temperature. A cooling duct directs air to the print head, but there’s only limited space in the printer for the duct. So how can the mass flow be improved without making the cooling duct any larger?

Air-flow simulation

Using the Simcenter Star-CCM+ simulation tool, the developers first analyzed how air flows through the cooling duct. Undesired eddies shown in red were almost entirely eradicated as a result. Changing the interior of the cooling duct by optimizing its geometry step by step improved the mass flow by 22 percent. Any remaining edges were smoothed in an additional stage of shape optimization.

Best possible 3D printing

That’s where the NX software comes into play: Convergent Modeling and the Design Checker were used to ensure that the cooling duct could actually be manufactured and installed. This step included adding a mounting flange and checking to determine whether the predefined wall strength of the entire component had been maintained.

 

The associative, end-to-end nature of the Siemens solution represents two benefits that show their colors whenever more improvements are needed. They allow design changes to be automatically incorporated during upstream or downstream process stages. And until the component is printed, the user stays in an end-to-end software environment. 

Make the most of the print space

NX then optimized the print space inside the machine. The question was how to fit the maximum number of 3D printed parts into the machine, and how to shorten the printing time for a set order volume. This is where the software can relieve operators of the time-consuming task of filling the print space. Getting the most from print space can significantly reduce unit costs. And lastly, it makes production more sustainable, because there’s less waste per component.

Tecnomatix Plant Simulation can be used to run through manufacturing scenarios for entire plants or manufacturing lines at a virtual level. The number of parts to be printed, say 300,000, is specified, and the simulation software then determines the ideal parameters: for example, the number and positioning of additive manufacturing machines and automated guided vehicles (AGVs), or the number of machine operators required. 

Cloud: Even more undreamed-of opportunities

Only a cloud solution can make the process even more productive: Within five days, the developers created a MindSphere app to record, manage, and analyze all the data from 3D printing production. What’s the current status of each printer? What’s it currently printing? Are all the filters clean and otherwise in good working order? Is there enough polyamide in the 3D printer? How productive has the printer been since it began operation, and what has it printed since then? These are just a few of the many questions that MindSphere can answer immediately.
