Which 3d Scanner? Selecting the ideal 3D Scanner for your project

Selecting the ideal 3D Scanner to make your project successful . For most of us, investing in a 3D scanner is a completely new undertaking. This procedure is complicated as well as bewildering because each 3D scanning system has its own characteristics and utilizes different technologies (ie. laser, white-light, and stereovision).

Of all the 3D scanners that currently can be found in the marketplace, which one meets your requirements?

3D scanning is a technological innovation that can help you complete a project. Choosing the right scanner is dependent needs. Defining your needs enable you to make the right choice.

Here are some key questions you need to answer to help you with this process:

1. What exactly are you planning to scan?

Figuring out what you need to scan determines what features are critical when researching 3D Scanners. As an illustration, a 3D scanner that’s competent at checking human faces might not be ideal for checking structures. The more specific you’re at determining what you need to scan, the easier it will be to look for a 3D scanner to suit your specific requirements.

2. How big is the object target?

The majority of 3D scanners are designed for a specific scanning window or object size. Almost always you would need to use different scanners to scan objects of different sizes. For instance, you should use a different 3D scanner for scanning jewellery as opposed to scanning a car. The majority of 3D scanners are optimized to scan objects from roughly a few inches to two feet. The further you go from this standard size, the more expensive the 3D scanner will be.

3. How accurate do you want your scan to be?

We all want to our scanning object to be replicated as accurately as possible. In scanning the accuracy is based on the depth value or Z axis and is measured in macrons. The less macrons you have the more expensive the scanner will be. A 5 micron scanner could cost around $150,000 where as a 50 micron scanner could be around $10,000. This is a massive factor when choosing a 3D Scanner!

4. What amount of resolution do you want} for your scan?

Resolution measures just how much detail you’d like to acquire from the object that you are scanning. You could have a very accurate 3D scanner that just collects 10 points in one scan or perhaps an inaccurate 3D scanner that collects millions of points. Both of these 3D scanners serve an alternative purpose. Like accuracy, just how much resolution you would like will certainly have a direct influence on the cost of the 3D scanner. Higher resolution scanners that grab more detail will definitely cost more.

5. How fast do you need the 3D scanner to scan?

Scanning of static objects: the scan time usually is not important unless you are carrying out a large number of scans.

A single scan taking less than a minute is appropriate for many of us. For scanning people, a faster scan speed is needed as it’s tough to stand still for lengthy time periods. A scan speed of 1.5 seconds or less work best. You should take into account that processing the resulting scan data also takes some time, and faster processing speed is commonly linked to more expensive scanner.

6. Once you have completed the scan what do you plan to do with the data?

For most people, 3D scanning is the beginning of the project. Scan data is ultimately utilized for other purposes, such as CNC, ( Computer Numerically Controlled), to mill out an object, for visualization or inspection.

The downstream data path is different for various applications. This helps to ascertain the features you’ll need in a scanner and which other data processing software you must have to complement the scanner.

After getting your 3D data, you will find that there are data clean-up and data conversion tasks that must be done in other software applications.

7. What is your scanning environment?

Different scanners work well in different environments. The majority of 3D scanners work efficiently in a well-lit office environment.

Out of the office such as in a moving vehicle or static outdoors scanning will incur extra costs due to the complexity of the project.

In a normal office environment scanner requirements are less expensive.

8. What is your budget?

If money is no object then hey great news!! However, for most of us the budgets are tight, so there needs to be a compromise and that is to make do with less features – prioritize those features and this will make your job less challenging and less expensive.

9. Who will be operating the scanner?

You must have a trained scanner operator to get the best results, do not cut corners in training people as you will not be able to generate the best results.

10. Do you need any specific features?

Remember if you are looking for a specific feature make sure the scanner you choose is able to perform this task. Do you want the scanner data to integrate with a particular application? Make sure you list your specific needs and discuss them with the manufacturer as it may be that extra costs could be involved.

In summary it is important that your 3D scanning project is water tight and it may be an idea to get consultancy from scanning specialists to help you get the best results.
