FREMONT, CA: Since the days of rapid prototyping, additive manufacturing has come a long way. From their inception, 3D printing technologies have found a wide range of uses, including lowering production costs and lead times, improving product performance, and enabling large-scale mass customization. Nonetheless, when it comes to large-scale production, AM has significant obstacles. Here are four challenges faced by additive manufacturing:
Production volumes
Additive manufacturing workflows must be both rapid and scalable to accommodate the high quantities and short lead times required for serial production. When compared to traditional manufacturing methods, most AM systems currently lack the speed required for large production.
While manufacturers of AM hardware are working on quicker solutions to remedy this, print time per part is only one element of the puzzle. All pre-and post-processing procedures have an impact on prospective throughput and must be considered.
Identifying a business case
Building a business case for additive manufacturing is difficult for many organizations, especially given the hefty startup costs. Lower tooling costs, the capacity to produce complicated geometries cost-effectively, and cost-effective customization are just a few of the long-term financial benefits of additive manufacturing.
But, upfront investment in technology, ranging from hardware to materials and maybe post-processing equipment, will be necessary.
Material availability
Materials development has progressed significantly since the days of proprietary filaments. Metals, ceramics, polymers, and composites are among the materials that can currently be printed using 3D printing technology.
Despite this, one of the most significant challenges to employing additive manufacturing as a production process is the lack of suitable materials. Only a few numbers of suitable materials are available, limiting material diversity.
Repeatability
When it comes to series production, the importance of repeatability cannot be overstated. Consistently creating dependable parts, on the other hand, is a continual issue for AM. Even when identical settings are used, variances in the production of the same part can occur.
Part orientation within the build platform, machine calibration, material quality, and how pieces are removed from a build are just a few of the elements that can affect the quality of a finished part. To ensure a successful print every time, all of the process variables must be precisely defined and managed, which is no minor job.
