3D scanning for 3D printing is an invaluable technology that transforms how we create and replicate objects, specifically for 3D printing.
While some 3D printing projects utilize open-source or pre-made models, custom jobs require the creation of original designs from physical objects. This is where 3D scanning becomes essential, saving considerable time and enhancing accuracy.
Choosing the right 3D scanning system can be daunting due to the myriad options available. This guide will cover everything you need to know about 3D scanning technology, its benefits, and how partnering with a trusted 3D scanning company can elevate your business operations. 
Understanding 3D Scanning for 3D Printing
3D laser scanning involves using laser light, structured light, along with a series of camera to create precise digital models. The process starts with directing a laser point or line at the object to be scanned.
Specifically mentioning a blue light laser scanner that we use in our business, data is recorded by triangulation to measure the laser’s interaction with the object’s surface.
Triangulation in the context of 3D laser scanning is a method used to determine the three-dimensional coordinates of a point on an object’s surface. This technique relies on the geometric principle of triangulation, which involves measuring distances and angles to form a triangle.
This interaction is recorded as a series of data points, each assigned coordinates (X, Y, and Z). Thousands to hundreds of thousands of these data points are captured from various angles to build a complete 360° scan, resulting in a point cloud. 
Essentially anything can be recorded by 3D scanning for 3D printing projects. The point cloud created serves as the foundation for creating detailed mesh and CAD files for 3D printing. Depending upon the complexity of the parts means you can either scan directly to a 3D print file, like STL, or convert the data to manufacturable CAD files.

The Benefits of 3D Scanning for 3D Printing
What are the benefits of using 3D scan data for 3D printing? Collectively here are the top perks of using 3D scanning services.
Speed and Efficiency
3D laser scanning can capture thousands to tens of thousands of data points per second. This rapid data collection significantly reduces the time required to complete scans, allowing projects to progress faster.
Whether scanning small objects or large assemblies, the efficiency of 3D scanning accelerates the overall workflow.
Precision and Accuracy
3D scanning technology offers remarkable accuracy, with some systems achieving precision levels as fine as 0.002-0.197 inches.
This high degree of accuracy ensures that the scanned models are precise, reducing the need for extensive revisions in the design and production stages. Accurate scans mean fewer errors and a smoother transition from design to 3D print.
Cost-Effectiveness
Compared to traditional measurement and modeling methods, 3D scanning is highly cost-effective. The technology requires less time and labor for data acquisition and design iterations, resulting in significant cost savings.
By minimizing manual work and streamlining processes, 3D scanning makes high-quality 3D printing more accessible and affordable.
Choosing the Right 3D Scanning System
3D laser scanning systems are not created equal. With any modern technology there is a sliding scale of accuracy that is directly related to cost.
When selecting a 3D scanning system for your needs, consider the following factors:
Application
Different projects may require different types of scanners. For instance, small, detailed objects might need a scanner with high resolution, while larger objects might benefit from a system with a broader scanning range.
Are you recreating aerospace-grade parts with a miniscule margin of error? Then you will require a platform that has both a higher accuracy and higher budget.
Hobbyists might only need a basic 3D scanner that can quickly create a model. Projects like figurines, simple shapes, and limited textures.
Budget
3D scanners vary widely in price but not all laser scanners are the same. Determine your budget and compare it against the features and capabilities of available scanners to find the best fit for your needs.
Generally, industries requiring high tolerances will need a high budget for a 3D scanning platform. For these uses, sometimes even 3D printing is not the best production option either.
Accuracy and Resolution:
Depending on your project requirements, you might need a scanner that offers higher accuracy and resolution. Evaluate the specifications of various scanners to ensure they meet your project’s standards.
Depending upon the demand of 3D scanning for 3D printing projects in your business, it may be a better option to hire a service provider.
Should you even buy a 3D scanner if you do not need to use it frequently? 3D laser scanning platforms also require software, training, and a computer powerful enough to handle scan data; which can be in gigs of space.

Practical Tips for Effective 3D Scanning and 3D Printing
To maximize the benefits of 3D scanning for 3D printing, consider these practical tips when preparing your project to be scanned:
Prepare the Object
Ensure the object to be scanned is clean and free of any debris that could affect the scan quality. In some cases, applying a matte spray can help reduce reflections and enhance scan accuracy.
Optimal Scanning Environment
Specifically for mobile scan service, try to create a controlled environment to minimize external factors like lighting changes or vibrations that could impact the scan data. 
Our platform only needs access to a standard 110V plug and space to move around. Being out of the elements, especially water, helps work towards a successful scan process.
Discuss Your Project Goals
Are you looking for a quick prototype? Is this the end process of a large project? Be open to the idea of also not using 3D printing as other processes may be more budget friendly in the long run.
