Overview: 3D Printing

3D printing (additive manufacturing) builds parts layer by layer straight from CAD data – with no tooling or mould costs. This pays off for prototypes, one-offs and small batches with complex geometry. Katena offers parts made by Murtfeldt, whose 3D competence centre in Kusterdingen near Tübingen uses four processes: selective laser sintering (SLS) with polyamide 12, fused layer modelling (FLM, also known as FDM) with ABS and TPU, digital light processing (DLP) for particularly smooth surfaces, and VFGF large-format printing with a build volume of 1700 × 1050 × 1050 mm.

SLS materials include PA2200 (PA12), aluminium-filled Alumide and glass-bead-filled PA3200GF; for food and pharmaceutical uses there is the through-coloured MurSint PA12 blue. Parts can then be dyed, painted, ESD-coated, infiltrated, vibratory-finished, PUR-coated or smoothed with MurPearl, and fitted with thread inserts, machined and assembled into complete modules.

FAQ: 3D Printing

Which 3D printing processes does Murtfeldt offer?

Murtfeldt works with four processes. In selective laser sintering (SLS) a laser fuses polyamide 12 powder layer by layer, so no support structures are needed. FLM builds parts from melted filament, DLP cures resin with UV light for very precise, smooth surfaces, and VFGF processes granules through a variable nozzle into large-format parts. The right process depends on size, tolerance, material and quantity.

Are 3D-printed parts suitable for food contact?

For this Murtfeldt developed MurSint PA12 blue: through-coloured and therefore visually detectable even as a fragment, with the material regulated by the FDA. Murtfeldt states EU food compliance for parts in combination with its own MurPearl smoothing process, which is also applied to PA2200 and Alumide. The smoothed surfaces are sealed and repel water and dirt.

How accurate and robust are printed parts?

That depends on the process. According to Murtfeldt, SLS parts made of PA2200 are strong, detailed, stable over the long term and highly wear-resistant; PA3200GF is particularly dimensionally stable and stiff. With FLM the layers remain visible and properties can vary with direction. Where fits are required, Murtfeldt recommends machining such as drilling, reaming, turning or milling; thread inserts are possible from M2.5.

For which quantities is 3D printing worthwhile?

Because no tooling has to be built, 3D printing is most economical for prototypes, one-offs and small batches. Murtfeldt produces anything from single parts to series and supplies purely printed, finished or machined parts right up to assembled modules. Whether printing or conventional machining is the better choice is best clarified with Katena on the basis of your drawing or CAD data.
