Central Scanning Blog // 3D Scanning or 3D Printing: What’s the Difference?

In this blog Central Scanning discusses the distinctions between the cutting-edge technologies, 3D Scanning or 3D Printing, shedding light on their unique roles in industries like healthcare and conservation. Discover the pivotal differences that make them indispensable forces in modern innovation.

Technology has evolved at an unprecedented rate in recent years, particularly within the field of 3D scanning and 3D printing.

From optimising everyday business operations to revolutionising healthcare with innovations like the world’s first 3D-printed human cornea, and even aiding marine conservation with 3D-printed coral reefs.

But what’s the difference between 3D scanning and printing? Are they the same thing? Or are they two different disciplines? We have specialised in the world of 3D printing and scanning for over a decade. Therefore, we take a look at the processes in more detail, providing you with an insight into the world we live and breathe, day in, and day out.

What is 3D scanning?

3D scanning is a fast, efficient process that’s used to collect 3D point cloud data to create three-dimensional models. Using specialist software, the 3D data is then quickly processed into a triangle mesh or STL file. After that, we can then use this for a range of applications, including comparison to CAD and 3D printing.

What are the benefits of using it?

It’s fast, flexible, highly accurate, can be used by a wide range of applications and capture large amounts of high-quality data.

What’s it used for?

3D scanning involves using non-contact, accurate measuring systems that are used to provide accurate and reliable data. It interfaces with standard 3D CAD packages for fast, effective, quality inspection and analysis.

3D scanning is a particularly useful tool for reverse engineering, prototyping, model-making, pattern and tool-making and 3D printing (which we’ll move on to shortly).

The systems are as diverse as the projects they’re used for. Take our range of 3D scanning systems, for example. They are designed to capture the precise measurements of complex surfaces, geometries and sharp edges across a wide spectrum of objects of all shapes, sizes and textures. One of the Artec EVA scanners we supply has recently proven pivotal in helping safeguard the future of one of the most endangered species in the world.

In April, an Artec EVA scanner was used to carry out the first-ever 3D scan of a rhino’s head. His horn had been ripped out by poachers in South Africa. We were a part of a ground-breaking partnership project involving the charity, Saving the Survivors, ourselves and the University of Nottingham. Watch this short video below to find out more.

What’s 3D printing?

3D printing is an additive method of manufacturing. STL or CAD files are printed from a digital format to a physical object by laying down successive layers to build up the object. Items can be printed in a variety of materials and shades. It’s also possible to produce working models with moving parts in one go, using the additive manufacturing technique.

What’s it used for?

3D printing was most commonly used as a form of 3D rapid prototyping but nowadays, we are supplying more and more parts for production use where volumes do not justify tooling and/or if the design will be altered as part of the production.

Through 3D printing services and 3D rapid prototyping, many companies can verify and change designs more often, and more effciently. For instance, we can create 3D rapid prototypes within just 24 to 48 hours. This is due to our expertise (and the fact we use only the very best Markforged carbon fibre printers, Stratasys  Ultimaker Polyjet and FDM machines).

So, in the case of our ground-breaking rhino horn project, the valuable scans that were obtained using the Artec scanner are now being transformed into a 3D-printed prosthetic. It’s hoped that these 3D-printed prosthetics will go some way in providing a surgical solution. Helping repair the long-lasting, and often devastating damage, caused by poaching.

FAQ: Understanding the Differences Between 3D Scanning and 3D Printing with Central Scanning

What is the difference between 3D scanning and 3D printing?

3D scanning captures the precise measurements and details of an object to create a digital 3D model. 3D printing takes a digital model and creates a physical object by layering materials. Both technologies complement each other in various applications, from prototyping to conservation.

How does 3D scanning work?

3D scanning uses non-contact measurement systems to collect high-quality data and create accurate 3D models. This data can be used for a range of applications, including CAD comparison, reverse engineering, and 3D printing.

What are the benefits of 3D scanning?

3D scanning is fast, flexible, and highly accurate, making it ideal for capturing complex surfaces and geometries. It is widely used in industries like healthcare, conservation, and manufacturing for tasks such as prototyping, quality inspection, and reverse engineering.

How does 3D printing differ from traditional manufacturing?

3D printing is an additive manufacturing process that builds objects layer by layer from digital files. Unlike traditional manufacturing, which often involves subtractive processes, 3D printing allows for rapid prototyping and the creation of complex geometries that would be difficult or impossible to achieve with other methods.

Why should I choose Central Scanning for 3D scanning and printing services?

Central Scanning combines expertise with cutting-edge technology to offer comprehensive 3D scanning and printing services. Whether you need to prototype a new design, create a custom part, or preserve an endangered species, we provide tailored solutions to meet your unique needs.

What are the benefits of using it?

3D printing enables you to prototype ideas quickly. As well as bring projects to life and print in a variety of materials and geometries that no other technology can.

Moreover, 3D scanning and 3D printing are two different techniques within the same rapidly evolving world where virtually anything is possible (with the right technology and know-how) and the opportunities are endless.
