porsche classic now produces rare parts using 3d printer

by:QUESTT     2020-08-04
Porsche classics, the division dedicated to classic cars for Porsche, has come up with a solution to produce extremely rare parts that require only a small number of parts: a 3D printer.
The Porsche Classic series currently has about 52,000 parts.
If a part is no longer in stock or inventory is decreasing, copy the part using the original tool.
For larger quantities, new tools may be required for production.
However, it is a major challenge to ensure that only a very limited number of spare parts are needed, as it is inefficient to produce small batch products using new tools.
Let\'s take Porsche 959 as an example, with only 292 examples.
The release rod of the 959 clutch is made of gray cast iron, and the quality requirements are very high, but the demand is very low.
German automakers claim that the only process worth considering now to make it is selective laser melting.
To manufacture a release rod, a layer of powder tool steel should be added in a range less than 0.
In the process of computer processing, 1mm thick is applied to the processing plate.
High in an inert atmosphere
The energy beam then melts the powder in the desired position to form a steel layer.
So the three complete
Production size components in layers.
The pressure test with a load of almost 3 tons and subsequent internal fault tomography both passed the printed release rod with flight color.
The practical test of the lever installed on the test car and the extensive driving test confirm the impeccable quality and function of the components.
As positive results have been received so far, Porsche is currently making eight other parts using 3D printing.
The parts discussed are steel and alloy parts produced using a selective laser melting process, as well as plastic parts made using a selective laser sintering printer.
Sintering is a process of heating the material to a slightly lower melting point, and the remaining energy is applied to the selected point by laser to melt the plastic powder.
Although all parts generally meet higher standards, they are at least bound by the quality requirements of the original production cycle.
By testing the installed parts, the accuracy of the size and fit is ensured.
Depending on the field of application, plastic parts made of various materials must be able to resist oil, fuel, acid and light.
Porsche classics is currently testing whether 3D printing is suitable for the production of more than 20 components.
Benefits: Three-
The dimensional design data or 3D scanning of the part is a sufficient basis for starting production.
Components can be produced on demand if needed, eliminating tooling and storage costs.
Porsche Classic Post is now releasing products for the first time on Carmudi, Philippines that use 3D printers to produce rare parts.
