No Strings Attached: How Low-Angle Printing Is Reshaping Additive Manufacturing
In additive manufacturing (AM), support structures have long been a necessary trade-off — offering stability but at the cost of additional material, time, and post-processing effort.
However, advancements in low-angle printing are redefining these constraints, allowing manufacturers to break free from traditional support-heavy designs. For the AM industry, this shift opens up new possibilities for internal designs and outer shapes, which weren’t possible before. This possibility does not only enhance durability and efficiency to improve sustainability and cost-effectiveness within the building process but also on post-process.
With no strings attached, low-angle printing is changing the way AM components are designed, manufactured, and scaled for production.
Expanding Application Horizons
Low-angle printing has long been associated with high-value applications in aerospace and energy — think impellers, turbine components, or stator rings. But its benefits extend far beyond these sectors.
From space to automotive, and from consumer products to medical devices, manufacturers across industries are using low-angle printing to realize:
- Greater design freedom: Reduced need for internal supports opens up new possibilities for complex geometries and application-specific designs.
- Lower material usage and production costs: Minimizing support structures means less material is consumed, which also translates to cost savings.
- Faster production and simplified post-processing: Fewer support structures reduce build time and post-processing effort.
- Improved cooling efficiency: Larger, conformal channels become easier to print, boosting performance in injection molding applications.
- Higher precision for fine features: Excellent dimensional accuracy makes it ideal for thin structures and intricate details.
- Enhanced surface quality: Particularly for down-facing areas, leading to better overall part aesthetics and function
By leveraging these capabilities, manufacturers can create components that are not only more efficient but also easier to post-process, saving time and resources.
Sustainability and Lifecycle Impact
With 85% of consumers reporting the first disruptive effects of climate change in their daily lives and 63% confirming the importance of eco-friendly products, sustainability is quickly becoming the foundation of every future-oriented business strategy.
While AM has always offered material efficiency advantages over subtractive manufacturing, an advanced low-angle strategy takes these benefits further, feeding into sustainability goals.
By minimizing or eliminating support structures, manufacturers reduce material waste, energy consumption, and post-processing efforts. A lifecycle assessment of low-angle printing compared to conventional AM methods reveals:
- Lower powder consumption, as fewer supports mean less wasted material.
- Energy savings due to reduced print times and post-processing steps.
- Extended tool lifespan, as optimized geometries enable better heat dissipation and reduced stress concentrations.
Additionally, through intelligent heat input in the downskin region, we improve print quality in low-angle geometries without increasing waiting times. This approach — originally learned from SmartFusion and now translated into hard-coded process features — helps stabilize overhanging surfaces and reduce defects. Combined with optimized exposure strategies, it ensures that low-angle features remain strong and manufacturable.
For OEMs looking to improve their sustainability credentials, adopting low-angle printing can help demonstrate a commitment to responsible manufacturing.
User Experience and Software Evolution
One of the biggest barriers to adopting new AM techniques has historically been the complexity of design software. However, modern tools have evolved to make low-angle printing more accessible than ever.
Software solutions now incorporate:
- Automated support optimization, allowing users to experiment with low-angle designs without requiring expert knowledge.
- Real-time simulation and analysis, ensuring manufacturability and performance before printing begins.
- Intuitive UI enhancements, making it easier for designers and engineers to iterate quickly and confidently.
For many industries, where precision and repeatability are non-negotiable, these advancements mean manufacturers can push the boundaries of what’s possible without a steep learning curve.
Scaling Up: From Prototype to Production
While low-angle printing offers clear advantages in prototyping, its real test lies in production scalability. Fortunately, as the technology matures, its ability to support large-scale manufacturing is becoming increasingly viable.
Key factors influencing scalability include:
- Process repeatability, ensuring that parts produced in batch manufacturing maintain consistent quality.
- Post-processing efficiencies, with reduced need for support removal leading to faster turnaround times.
- Integration with hybrid manufacturing, where printed tooling inserts can be combined with traditional machining for optimal performance.
