SLS 3D Printing for End Use Parts: OctoClassic Case Study

Sinterit's OctoClassic SLS 3D printing case study shows SLS 3D printing for end use parts in its purest form. A 2019 startup. A polypropylene power steering fluid cap. A classic Mercedes back on the road in days. No mould tooling. No injection moulding minimums. One Sinterit machine, one polymer, one redesigned part fit for service.

Background: a 2019 startup born from two passions

Filip and Krystian founded OctoClassic in 2019. They share one problem worth solving: classic car owners cannot buy parts the manufacturer no longer makes. Filip brings restoration. Krystian brings 3D engineering. Together they produce professional spare parts for vehicles the original makers have long since stopped supporting.

To prove the idea, they tested it on Filip's Mercedes SL500. Their first target was the sun visor trim cover. It is a notorious failure point because of weak geometry and constant sun exposure. They reengineered it, reinforced it, and printed it. Other SL owners noticed and ordered their own.

The problem: no manufacturer wanted the low volumes

Classic car spare parts sit in a manufacturing dead zone. Production volumes are too low for injection moulding to be economic. Original tooling is long gone. Aftermarket stock runs out. Owners are left chasing dwindling supply at climbing prices.

Almost no manufacturer wants the work. Krystian and Filip saw 3D printing as the only cost-effective option. Their hobby quickly became their mission. Hunt for parts about to disappear from the aftermarket. Build a digital replacement. Make it last longer than the original.

How OctoClassic uses Sinterit Lisa PRO for end use parts

OctoClassic uses an industrial 3D scanner to capture the geometry of a broken or worn part. Engineers rebuild it in CAD with fits and tolerances suited to modern hardware. The redesigned part prints on a Sinterit Lisa PRO, the company's chosen SLS platform.

SLS suits final parts for three reasons:

• Isotropic strength across the printed part

• No support structures to remove or scar surfaces

• Mechanical performance close to injection-moulded equivalents

For low-volume 3D printed automotive parts in functional applications, cost per part is in the right zone and the result lasts.

A polypropylene power steering fluid cap, on demand

A classic Mercedes power steering fluid cap sits at the centre of the case study. The owner contacted Krystian after failing to find a replacement anywhere on the aftermarket. OctoClassic scanned the original, redesigned it to fit modern nuts, and printed it on the Lisa PRO in polypropylene.

Polypropylene SLS 3D printing earned the call for its chemical resistance and toughness. Polypropylene is one of the few SLS-printable polymers surviving long-term exposure to hot oils, fuels, and engine fluids without becoming brittle. The cap was on the car within days of the order. The Mercedes was back on the road.

What SLS 3D printing for end use parts means for Australian buyers

Replacing the Sinterit Lisa PRO in OctoClassic's setup today is the Sinterit Lisa X. The Lisa X runs faster. It uses the same Sinterit powder library, including PA-11.5 and polypropylene. It gives Australian manufacturers and restorers the same end-use part economics from a smaller footprint.

For Australian classic car restorers, vintage motorsport teams, and short-run automotive workshops, the OctoClassic playbook for SLS 3D printing for end use parts scales cleanly. Own a Sinterit Lisa X. Stock the relevant polymer. Scan or model the failed part. Print on demand. A Sinterit Lisa X starts at AUD $37,734.99 in Australia. The Sinterit Suzy sits below the Lisa X for businesses starting smaller.

Frequently asked questions

Can SLS 3D printing produce end-use parts?

SLS 3D printing for end use parts is now a mainstream choice for low-volume functional components. SLS produces isotropic parts without support structures. Mechanical performance is close to injection-moulded equivalents. OctoClassic uses a Sinterit Lisa PRO to produce final automotive spare parts in polypropylene.

Which Sinterit polymer is best for high-strength final parts?

Sinterit offers four high-strength polymers for SLS 3D printing for end use parts. Polypropylene handles chemical resistance. PA-12 Industrial covers general engineering. PA-11 CF adds stiffness and structural rigidity. PA-11.5 absorbs impact. OctoClassic picks polypropylene because it survives long-term contact with engine fluids.

Is 3D printing cost-effective for low-volume car parts?

3D printed classic car parts are cost-effective when injection-moulded production volumes are too low to be economic. No tooling cost. No minimum order quantity. A Sinterit Lisa PRO or Lisa X produces a single spare part on demand. Exactly what classic car owners need when the original part is gone from the market.

What replaces the Sinterit Lisa PRO in 2026?

Sinterit Lisa X is the current flagship replacing the Lisa PRO. The Lisa X uses a galvanometer laser system. It prints faster than the older Lisa PRO. It runs the full Sinterit powder library plus newer polymers like PA-11.5. OctoClassic's playbook applies on either machine.

How much does a Sinterit SLS printer cost in Australia?

Pricing in Australia starts at AUD $37,734.99 for a Sinterit Lisa X. Sinterit Suzy sits below the Lisa X. Both come in dramatically lower than large industrial powder-bed SLS systems. This is why end-use part bureaus build their business model around compact Sinterit machines.
