Advanced Additive Manufacturing

Additive manufacturing (AM), also known as 3D printing, is an innovative suite of advanced technologies that enables the fabrication of medical components and products with remarkably complex and high-resolution features which often cannot be achieved within the constraints of conventional manufacturing methods. Compared to traditional subtractive machining methods, AM is more efficient and can deliver functional prototypes into the hands of medical engineering teams within a matter of days, instead of weeks. Spectrum has developed groundbreaking, proprietary AM technologies for creating medical products that the competition cannot, such as high-precision, medical-grade single and multi-lumen tubing—a first in the industry.

Additive manufacturing is a rapidly advancing field as new technologies, equipment, and specialized materials continue to enter the market. Spectrum’s industry-leading AM capabilities enable more creative design, innovative rapid prototyping, and seamless transition to high-volume manufacturing.

Benefits of Spectrum’s additive manufacturing capabilities and services include:

• Customized and/or proprietary processes, equipment, and materials for a wide range of medical applications
• Creating innovative, one-of-a-kind medical device components that advance the manufacturing boundaries of what is possible, especially for minimally invasive surgical processes and life-saving devices such as stents
• Spectrum’s dedicated additive manufacturing technical team has the depth of knowledge and experience to determine the best AM approach for your project, meeting even the most challenging timelines
• Rapid prototyping that can deliver production-ready prototypes in a matter of days instead of weeks, accelerating project development and informed decision-making
• Bridge manufacturing that utilizes additive manufacturing/3D printing to test low-volume production runs of a product before investing heavily in a mass-production process using standard methods of manufacturing 

Spectrum uses additive manufacturing technologies to process all medical-grade thermoplastic materials. These include Nylon, Pebax®, polypropylene, polycarbonate, acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), PEEK, polyetherketone (PEK), high impact polystyrene (HIPS), Urethanes, and custom materials.

Product design and performance parameters include:

• Medical-grade USP Class VI and/or ISO 10993 materials and
  additives that are biocompatible, traceable, and certified
• Low-to high-durometer materials (60A 85D)
• Low-to high-temperature materials (PLA-PEEK)
• Multi-material parts, utilizing up to four different materials
• Lumen sizes as small as .010”
• Tubing walls as thin as 0.006” with current development underway to achieve 0.003”
• Print volume—micro prints, large prints, infinite length prints

Quick-turn prototyping is essential in medical device manufacturing today. Time to market is a top priority for medical device manufacturers—delivering functional prototypes into the hands of all stakeholders as soon as possible allows for more-informed decision-making and shorter time to market.

Lead times can be as short as:

• 3-5 days for most additive manufacturing prototypes
• 1-2 weeks for higher-volume orders or complex designs

Bringing a medical device to market can take years and requires deep expertise in identifying product requirements and the best product design to meet clinical needs. Spectrum’s additive manufacturing capabilities allow medical-device designers to select from a wide range of medical-grade plastics with specifically engineered material characteristics and design components, including, multi-material and multi-dimensional builds.
