Rising Demand from the Aerospace Sector
The increasing demand for SLS from the aerospace and defense sector is a major factor driving the growth of the selective laser sintering market. Aerospace manufacturers work with lightweight, strong assemblies with restrictive safety regulations, and selective laser sintering (SLS) enables fabrication of pieces with complex geometry. This technology enables high-complexity, low-volume production, a strategy that accords with aerospace demand for prototyping. Aerospace manufacturers require rapid prototyping for accelerating product development cycles. Companies such as Boeing and Lockheed Martin embraced SLS for developing engine parts, including brackets and air ducts.
In 2024, NASA demonstrated the capability of successfully testing more than 100 additively manufactured parts in spacecraft, many of which were made using SLS processes for thermal and mechanical robustness. Furthermore, America Makes reported that aerospace is one of fastest growing industries in the adoption of additive manufacturing in the U.S., specifically in powder-bed fusion equipment such as SLS, as they satisfy the defense-grade material demands.
High Costs and Scalability Challenges
SLS is expensive, especially for low-volume production runs. This limits its adoption in some industries. Parts developed from SLS often require post-processing steps like finishing and cleaning, increasing the production cost. In addition, scaling up production creates challenges and requires substantial investments in additional equipment. The layer-by-layer sintering process consumes a large amount of time for each component. The fact that the cooling time is high for each layer’s solidification before proceeding to the next increases the whole process time.
Surging Investments in Digital Manufacturing Infrastructure
Increasing investments in digital manufacturing infrastructure is expected to create immense opportunities for key players competing in the selective laser sintering market. Smart factories and Industry 4.0 evolution continue to receive greater resource allocations from governments and the private sector. The rising demand for smart factory solutions opens up the way for additive manufacturing systems, such as SLS. In 2024, the Department of the Energy’s (DOE) Advanced Materials and Manufacturing Technologies Office (AMMTO) announced an investment of USD 33 million for smart manufacturing efforts.
