The initial application of aluminum in 3d printing can be traced to the year of 2011, when 3D printing was primarily used for polymers.<\/p>\n
Whilst its adoption is relatively slower compared with that of steels and titanium alloys, significant progress has been made in the development of novel processes, alloys, and applications in the past 15 years around.<\/p>\n
SmarTech Publishing (somewhat conservatively) once expected aluminum AM part production to overtake prototyping by 2027.<\/p>\n
Unionfab\u2019s Success Story of Aluminum 3D Printing in Aerospace<\/h2>\n
One of the wide applications of aluminum 3d printing to produce end parts is in aerospace. We, Unionfab, have recently helped an aerospace client out via utilizing this technology. The following is some background information.<\/p>\n
Client Background<\/h3>\n
The client is an innovator in developing advanced plenums for aircraft engines. They planned to develop a high-performance engine plenum that would:<\/p>\n
- \n
- \n
Optimize airflow<\/strong> for better engine performance.<\/p>\n<\/li>\n
- \n
Reduce weight<\/strong> without sacrificing strength.<\/p>\n<\/li>\n
- \n
Ensure durability<\/strong> in harsh aviation conditions.<\/p>\n<\/li>\n<\/ul>\n
Solution<\/h3>\n
Unionfab offered a solution combining sheet metal fabrication<\/strong> and SLM 3D printing with AlSi10Mg<\/strong> to manufacture the engine plenums.<\/p>\n
- \n
- \n
Material Selection<\/strong>: Aluminum alloy<\/strong> was chosen over plastic for its perfect balance of strength, weight, and durability. It ensures reliability in harsh aviation conditions while being cost-effective for production.<\/p>\n<\/li>\n
- \n
Stringent Aerospace Standards<\/strong>: The parts were produced by Unionfab\u2019s AS9100D-certified team, meeting the rigorous demands of the aerospace and defense industries.<\/p>\n<\/li>\n
- \n
Precise 3D Printing<\/strong>: The intricate geometries required for the plenums and injector pipes were achieved with Unionfab\u2019s cutting-edge SLM 3D printing technology.<\/p>\n<\/li>\n<\/ul>\n
Result<\/h3>\n
The collaboration delivered exceptional results. To ensure a perfect fit, Unionfab also provided a free assembly test<\/strong>.<\/p>\n
- \n
- \n
Enhanced Performance<\/strong>: The 3D-printed plenum optimized airflow, improving the engine\u2019s efficiency and reliability.<\/p>\n<\/li>\n
- \n
Durability & Weight Reduction<\/strong>: AlSi10Mg<\/strong> maintained strength while reducing weight by 1\u20132 kg<\/strong>.<\/p>\n<\/li>\n
- \n
Fast Turnaround<\/strong>: Parts were manufactured and delivered within two weeks<\/strong>, meeting critical deadlines.<\/p>\n<\/li>\n
- \n
Eco-Friendly Manufacturing<\/strong>: 3D printing minimized material waste, aligning with Unicorn Aviation\u2019s sustainability goals.<\/p>\n<\/li>\n<\/ul>\n
The success of this collaboration was largely due to aluminum alloy\u2019s cost-effective strength-to-weight ratio. With a 30% higher strength-to-weight ratio than stainless steel<\/strong> and 50\u201370% lower cost than titanium<\/strong>, AlSi10Mg became our top choice.<\/p>\n
So, what sets aluminum alloys apart from other common 3D printing metals?<\/strong><\/p>\n
Aluminum vs. Titanium vs. Steel vs. Copper vs. Nickle vs. Cobalt<\/h2>\n
In 3D printing, alloys outperform pure metals, which is why almost all 3D printing metals are alloys. Below, we\u2019ve summarized and compared the performance of common 3D printing metal alloys to help you choose the most suitable material.<\/p>\n
