Summary. Considering to buy a 3D scanner? Match your needs to the right equipment. 3D scanners offer applications like prototyping, site mapping, and reverse engineering. Weigh options between buying and renting based on frequency of use and budget. Ensure proper training for optimal results.
If you’re looking to buy a 3D scanner, it’s important to match the equipment to your purpose.
3D scanning has now become an essential part of fabrication workflows, both at the start of a project, and for quality control and design enhancement purposes upon completion.
There are numerous functions for a 3D scanner, including:
- Reverse engineering
- Measurement
- Duplication
- Prototyping
- Troubleshooting
- Site mapping.
With such a broad range of applications, how do you decide on the best kind of 3D scanner for you?
Also, in certain circumstances, does it make more sense to rent equipment rather than buy it outright?
What Types of 3D Scanner Are There?
3D scanners can be portable or fixed models.
Stationary and desktop scanners are for both indoor and outdoor use.
They are used in manufacturing and industrial design, in product design and quality control.
Desktop scanners can also scan historical and cultural assets for record-keeping, duplication and for reconstruction.
Desktop models include:
For example, the Artec Ray is a highly accurate long-range scanner, ideal for capturing large objects, including buildings and aircraft.
At the other end of the scale, as its name suggests, the Artec Micro is for precision scanning of much smaller objects, and is well-suited for detailed fabrication and manufacturing.
Portable scanners are for use in a broad variety of locations, and are especially useful for scanning moving objects.
These models include:
The Artec models are perfect for face and body scanning, and for aiding the manufacture of prosthetics and interior components of vehicles.
The ZEISS T-Scan Range is used in quality control processes, product design and reverse engineering.

How Accurate And Versatile Should Your 3D Scanner Be?
Accuracy will vary according to scanner models and the technologies they use.
Higher accuracy will be more expensive, but it may be also essential for your end purpose.
There are various combinations of accuracy and resolution available.
The Artec Micro, for instance, has precision, close-scanning capability, whereas the Artec Ray will maintain high fidelity scanning at distances of up to 110 metres.
Versatility will also be important, depending on what you intend to use your scanner for. The ZEISS Comet has flexible measuring volumes, and can scan different types of surfaces.
Consider, then, these factors when buying a 3D scanner:
- Accuracy
- Volume and coverage.
Should You Buy Or Rent A Scanner?
Whether you choose to buy or rent your 3D scanning equipment will very much depend on the volume of your work, the time it will take you, how much control you need over the process, and your budget.
Throughput is an important consideration. If you are intending to integrate 3D scanning more or less permanently into your processes, then buying may well be the best option.
Having an in-house scanning capability also means you have flexibility in terms of the time you allocate to it, especially if it’s going to be a frequent operation.
If, however, 3D scanning is a specialisation that you don’t wish to integrate into your work, or it is likely to be something you only need on occasion, then renting equipment is an alternative option.
Renting also means you can see how the technology fits with your current operation without committing to investing in it long-term.
The other major factor in deciding to buy or rent a 3D scanner is your budget. It is going to be better to choose the kind of 3D scanning equipment that will meet your needs, rather than simply opting for the cheapest on the market.
Alternatively, if you require sophisticated scanning functions then the affordable option might be to rent.

FAQ: Essential Considerations Before Buying a 3D Scanner
Why is it important to match the 3D scanner to your specific needs?
Choosing the right 3D scanner is crucial because 3D scanning plays a vital role in various fabrication workflows, from reverse engineering and measurement to prototyping and site mapping. Matching the equipment to your specific application ensures you achieve the desired outcomes, whether it’s high accuracy for small objects or wide coverage for large structures.
What types of 3D scanners are available, and how do they differ?
3D scanners can be broadly categorised into portable and stationary models. Stationary scanners, like the Artec Ray and ZEISS Comet, are ideal for high-precision tasks, including scanning large objects or capturing detailed data of smaller items. Portable scanners, such as the Artec Eva and ZEISS T-Scan range, offer flexibility and are perfect for scanning in various locations or capturing moving objects.
How do accuracy and versatility affect the choice of a 3D scanner?
Accuracy and versatility are key factors in selecting a 3D scanner. High-accuracy models are essential for tasks requiring detailed precision, like the Artec Micro for small objects or the Artec Ray for large structures. Versatility matters when you need a scanner that can handle different surfaces and volumes, such as the ZEISS Comet, which offers flexible measuring options.
Should you buy or rent a 3D scanner?
The decision to buy or rent a 3D scanner depends on several factors, including the frequency of use, budget, and the level of control you need over the scanning process. If 3D scanning is a core part of your workflow, purchasing a scanner might be the best option. However, if you only need it occasionally or want to test the technology before committing, renting could be a more cost-effective and flexible choice.
What expertise is required to use 3D scanning technology effectively?
While modern 3D scanners are user-friendly, specialised training can significantly enhance your ability to use the equipment effectively. Developing in-house expertise can be a valuable asset, enabling your team to explore additional applications and optimise the technology’s use within your business.
Can Central Scanning help with 3D scanner purchase or rental?
Yes, Central Scanning offers a range of desktop and portable Artec and ZEISS 3D scanners for purchase or rent. We also provide expert training on 3D scanning technology, calibration, and metrology to ensure you get the most out of your equipment.
Do You Have The Expertise For 3D Scanning?
Whereas cutting edge 3D scanning equipment is user-friendly, you could benefit from specialist training to ensure you can get the most out of it.
