3D printing for electronics with Arnite® T AM1210 (P) PBT

Using Arnite® T AM1210 (P) powder, manufacturers can 3D print electrical and electronic parts using PBT, the same material used in traditional injection molding. Additive manufacturing (AM) cuts material waste, energy consumption and shipping costs for automotive electronic component suppliers.
Task

Enable 3D printing for electronic and electrical parts

Additive manufacturing (AM) or 3D printing is already enabling car makers and auto electronics manufacturers to completely rethink their design and production processes. It is now possible to produce fully functioning electronic prototypes, end-use spare parts, and small-series components without expensive injection molding techniques. Additive printing also has the potential to save on material, energy consumption and shipping costs.

Polybutylene terephthalate (PBT) is a commonly used material in traditional injection-molded electronic auto parts, thanks to its good performance under a wide range of temperatures and in moist environments. Our task here was to offer customers a material that meets their needs for 3D-printed electric and electronic car components, and which can be processed for industrial production.   

By collaborating with Farsoon, we can offer customers a solution that brings higher accuracy and productivity, and lower cost per part.
By collaborating with Farsoon, we can help customers print more parts in the same amount of time, leading to lower costs per part and increased productivity, combined with higher accuracy.

Challenge

High-performance 3D-printed material for electronic parts

Components for automotive, industrial and power electronics must meet a wide range of stringent mechanical requirements as they affect occupant safety. These parts must withstand both short- and long-term exposure to high temperatures, ensuring there are no power breakdowns, leakages or short circuitries. 

Car fuse boxes bring a particular set of material challenges, as their function is to protect and insulate a vehicle’s electrical and electronic circuits from exposure to outside elements, while also regulating the current that flows through the wiring to each component. The fuse box material must deliver electrical and mechanical properties, as well as resistance to high and low temperatures.

PBT has long been a preferred option for traditional injection-molded electronic parts. The challenge here was to find the right material for a 3D-printed car fuse box that delivered all of the required technical characteristics.
 

Arnite® T AM1210 (P) powder enables us to integrate the properties of PBT into SLS 3D printed electronic components. This combination is an important foundation for our customers' market success.

Solution

SLS Farsoon 3D printing meets PBT: Arnite® T AM1210 (P)

Arnite® T AM1210 (P) is a PBT powder engineered specifically for 3D printing using selective laser sintering (SLS) technology. This innovation means electronic components can now be 3D-printed with the same material used in traditional manufacturing. We teamed up with Farsoon Technologies, an expert SLS printer technology, to provide an integrated material processing solution for an automotive fuse box. 

Combining Arnite® T AM1210 (P) powder with SLS technology, provides manufacturers a proven solution well-suited for electronic and electrical components that must meet demanding thermal exposure, dielectric and mechanical criteria. 

Without the need for extensive tooling, low-volume parts and prototypes can be produced more quickly and cost-effectively than with traditional techniques. Material waste, processing and shipping costs are reduced. This is an example of how material expertise can enable the additive manufacturing revolution in electronics volume production.
 

PBT powder Arnite® T AM1210 (P) is a material engineers are already familiar with and prepared to use. The production readiness of this 3D-printable material has been extensively proven by an independent global manufacturing leader.
