Contract manufacturing at S2S: FFF/FGF, ceramics, SLA and PolyJet

Which processes we produce for you, in which state you receive ceramic parts, and why an enquiry is often worthwhile despite the online calculator.

Contract manufacturing: processes and pricing · Watch the video on YouTube

Not every business needs its own machine. If the quantity is too small, capacity is lacking or a process is needed only once, we take on the production. This article sums up which processes we offer – and how you get to a price.

A price online, a quotation on request

Our website has a cost calculator: upload an STL or STEP file, choose material and process, see a guide price. For many parts that is enough.

Even so, with some processes it is worth us taking a look. Print times in FFF cannot be set across the board – we have a formula in place for it, but with quantities in particular a conversation gets to the right answer faster. Often the price then comes out lower than displayed: because parts can be stacked better, or because we can print five different components at once.

The service is aimed primarily at industrial customers. As a private customer you are equally welcome to enquire.

Filament printing: Prusa machines and a broad choice of materials

In filament printing we rely on Prusa printers, because we know the quality is consistent there. On materials we work with well-known manufacturers and cover a wide range from PLA through PETG to ABS.

One point that is often decisive for industrial customers: ESD-safe parts. For these we offer ABS-ESD, TPU-ESD and PETG-ESD.

Ceramics: in which state do you need the part?

We also produce ceramic parts from zirconia, aluminium oxide and other materials. Here there is no way around a conversation, because the decisive question is: in which state do you need the part?

  • As a green part – if you want to machine it yourself.
  • Chemically debound – if you run the sintering process yourself.
  • Fully sintered – if you need a ready-to-use ceramic part.

Why this makes sense and where the saving comes from we set out in our article Printing technical ceramics instead of grinding them.

SLA via partners: large parts for mould making

In cooperation with a partner we offer SLA – for parts up to around 70 to 90 cm. That is unusually large for this process.

The nicest use case is mould making. If you need small parts with high detail fidelity that do not initially have to be mechanically loadable, only once cast, the route runs via an SLA-printed mould for vacuum casting. At around 1,000 pieces that pays off clearly.

PolyJet: colour and rigid-flexible in one part

Also via a partner, we have access to a Stratasys PolyJet machine. It can print in colour and combine rigid with flexible areas.

In medicine and model making that is powerful: think of a human ear – firm cartilage, a soft lobe, in colour, in a single print.

Pellets: our own system

In pellet printing we work with our own machines. We process ordinary injection moulding pellets as well as ceramic pellets from our suppliers.

When it has to be fast: the at-risk order

For urgent cases the calculator offers an at-risk order. The price is generally somewhat higher, but we produce within one to two days or over the weekend.

If instead you want to play it safe, we look over it first – and usually the price then comes out lower than the figure displayed.
