Final Car Elements with SLS Prints of Very High Strength and Resistance: Octoclassic Case Study

Key points

• Redesign as a method to create reliable parts
• Creating parts not available on the market
• Powder materials precisely dedicated to the specific requirements of the parts

Background

OctoClassic produces professional spare parts for classic cars. Founded in 2019, the company combines expertise in classic car restoration (Filip) and 3D engineering (Krystian).

To validate the idea, the founders tested the concept on a Mercedes SL500. Their first project focused on the sun visor trim cover, a part known to break due to imperfect geometry and high sun exposure. The part was reengineered, reinforced, and 3D printed to eliminate failure. Demand quickly grew as other classic car owners recognised the improved quality and durability of the redesigned components.

Problem

Almost no manufacturers want to focus on classic car spare parts because the production volumes are too low. No manufacturing technology is cost-effective enough to bridge that gap, except 3D printing. This was an excellent opportunity for all classic car lovers like them.

Finding new parts suitable for 3D printing quickly became their hobby and mission. There are plenty of parts in different cars which are either difficult to find on the aftermarket or costly. This is precisely the scenario that happened to the classic Mercedes owner who needed to replace the power steering fluid cap, which is not available on the market. He decided to contact Krystian from OctoClassic to help him in solving this problem.

Solution

OctoClassic engineers carefully measured and analysed the power steering fluid cap’s geometry with their industrial 3D scanning equipment, and the team of 3D modeling engineers created a precise virtual representation of the original part using professional 3D CAD software.

The original part was redesigned to fit modern nuts and printed in the highest quality possible using a Lisa PRO 3D printer.

They decided to use polypropylene to produce the spare part because it guaranteed the final piece’s high durability. The quick printing process and mounting of the spare part allowed its owner to enjoy the ride again just a few days after the component malfunction occurred.

Krystian and Filip continue their work in supplying 3D printed replacement parts for classic cars, and their passion for keeping their customers’ vehicles in good shape is constantly growing. By involving the Lisa PRO for their projects, they can use different powder materials precisely dedicated to specific part requirements.
