The inside mirror base for the Mercedes-Benz 300 SL Coupé and the spark plug holder from the tool kit will now be available from the service partner via the Mercedes-Benz Classic Centre.
With the help of the 3D printer, Mercedes-Benz is continuously diversifying its range of genuine replacement parts. Replacement commercial vehicle parts are already being offered by the company since 2016, which are manufactured with the help of additive production. Recently, more replacement parts have received green signals with regards to the strict quality assurance at Mercedes-Benz with distinction and are coming onto the market.
The inside mirror base for the Mercedes-Benz 300 SL Coupé (W 198 model series), the spark plug holder from the tool kit, as well as the sliding sunroof rollers for the W 110, W 111, W 112 and W 123 model series are important replacement parts. They are once again available in genuine quality. Mercedes-Benz Classic has them newly produced in a 3D print. The process is particularly well-suited to smaller quantities and if the genuine tools are no longer available. This allows gaps in the replacement part supply of classic vehicles to be closed.
The printed inside mirror base of the 300 SL Coupé can now be obtained from the service partner via the Mercedes-Benz Classic Centre. Like the original, it is made from an aluminium alloy and subsequently receives high-quality surface chrome-plating. In comparison to the original, the new production includes a functional change: compared to the earlier original, the base is 42.5 mm longer and now measures 107.5 mm. This means the inside mirror sits a little higher and, in terms of road safety, offers an optimised view to the rear.
The spark plug holder was part of the standard tool kit of the 300 SL Coupé and Roadster, yet is suitable for several spark plugs with a spanner gap of 21 mm. The spark plug holder is also now available from the service partner via the Mercedes-Benz Classic Centre. Particularly on a hot crankcase, it serves to position the spark plug before it is tightened with a spark plug wrench and the right torque. The spark plug holder made from robust thermoplastic polyamide 12 (PA12) includes a modification that the 3D print makes possible. Instead of using a female connector, the spark plug is now securely held in place by a magnet. This means the holder can now be universally used for all spark plug types with and without SAE terminal nuts.
The sliding sunroof rollers for the W 110, W 111, W 112 and W 123 model series are an example of a component part with a concealed attachment, which ensures flawless function. The rollers are on the left and right of the sliding sunroof and are guided by metal rails. With the new production from the 3D printer, the sliding sunroof of the classic now slides like it did on the very first day. It is also made from robust PA12 and, from the end of 2018, can be obtained from every service partner via the central warehouse in Germersheim.
Together, even very sophisticated and complex component parts, for instance an instrument housing, are tested. The individual parts of the instrument housing are to be manufactured with the corresponding optimum production process. 3D printing especially shows its advantages when conventional processes for small quantities reach their technical or economic limits.
