Use of 3D printing/additive manufacturing growing in the UK

This is according to a recent survey by the GTMA (Gauge and Tool-Makers Association), which found that, unlike more traditional forms of manufacturing, 3DP/AM technology is not clustered geographically. Its flexibility means that it can be done in any location by small teams and individuals without the need for supporting infrastructure.

The survey also revealed a high level of adoption of metal powder as a building material. According to the GTMA, the early days of commercial adoption were based around resins, plastics, and other synthetic polymers, including binders for building sand-casting cores. The Association says this growth in metal-powder manufacture reflects improvements in the processing technology, availability of a wide range of metal alloys, and commercial demand.

The survey found that more than a third of material suppliers to 3DP/AM companies are offering metal powder and more than half of respondent companies are producing metal components and tooling.  There are also indications that other materials, including Kevlar® and carbon fibre, are being adopted.

The GTMA points out that, alongside the growth in metal 3DP/AM, there is an increased requirement for CNC machining, for finishing and support removal. The Association believes that as 3DP/AM technology becomes more widely adopted and better integrated with other manufacturing technologies, there will be further growth in metals manufacture and other high-strength, high-value materials.

The GTMA concludes that 3D printing is now demonstrating its ability to respond to the need for on-demand production and help alleviate supply-chain disruption. Globally, it says, the industry has overcome the hype of the last decade to emerge as a viable manufacturing technology in its own right.
