For engineers, designers, and management, one of the most critical additive manufacturing decisions -- along with choosing the hardware -- is selecting the software to use in an additive manufacturing, or 3D printing, system. Manufacturing is changing rapidly from a physical industry to a digital industry. Selecting the right digital infrastructure is critical to the efficient running of your additive manufacturing system.
It's more than simply getting the right software. You also need to use the right standards and services. The 3D file format you select as part of this process is a small but important piece of the additive manufacturing puzzle. Getting the 3D file format right at the beginning simplifies development and operation which leads to a faster, more efficient additive manufacturing process and a reduction in errors.
In short, the right 3D file format can help optimize and future-proof the additive manufacturing process for you.
Below are the five most important attributes a 3D file format should have, to help you fully realize the benefits of additive manufacturing.

1. Designed for additive manufacturing: Pick the right tool for the job.
For an efficient additive manufacturing solution that is optimized for productivity and designed to minimize error cases, select a file format that was designed for additive manufacturing. Many 3D file formats used today were developed years ago, for different purposes, and were simply never designed to operate efficiently in a modern additive manufacturing system. Formats not designed specifically for additive manufacturing can contain too little information, which is limiting, and they can contain extraneous information, which is inefficient.
2. Future-proof: A 3D file format's extensibility will help protect your investment.
3D printing hardware has surpassed the abilities of existing software. In other words, software is not quite capable of describing objects that could potentially be built on modern additive manufacturing machines. With this in mind, changes in your additive manufacturing processes are inevitable. Look for a file format that is designed with extensibility, so that you can take full advantage of technical advances and future-proof your additive manufacturing system.
3. Broad industry support: Broad industry support for a file format leads to standards.
Use a file format that is broadly supported by industry. This will reduce interoperability problems, and make it easier to select products that work well together. This means you'll experience fewer problems when you integrate products and services from several different companies.
Look for a file format that has industry endorsement so that you can be sure that new additive manufacturing capabilities will be adopted promptly. Think through all of the use cases where people in your organization will be using the file, and consider the cost of having file viewers available for all of your users. Some formats have viewers natively supported in the operating system, which mitigates the cost of deploying a separate viewer.
4. Minimize exceptions: Edge cases and exceptions reduce productivity.
Whether designing a 3D printing workflow, or choosing an
