Professional 3D Scanning Services for any purpose

When it comes to gathering measurements for reverse engineering or inspection of a product, nothing compares to the speed and quality of today’s 3D scanners. The industry of metrology has created many options of 3D scanners for large to small parts. It is even possible to scan the entirety of a airplane with the systems on the market today!

Barriers of Entry

The largest barrier of entry to many of today’s technology is justifying the capital expense of acquiring and training personnel in processing the data obtained by 3D scanning. It is these times when you have that one project that would benefit from bringing in a third party to reduce the initial investment and get the job done.

The same is still true when you are wanting to implement 3D scanning in your current processes. You want to make the most of your initial capital investment, so bringing in a third party to help with implementing processes can eliminate time taken from your primary operations and use the experience of the third party to iron out the 3D scanning process to your needs as quickly as possible.

How Does it Work?

There are a number of different types of 3D scanners out there, but at their core, they all do the same thing: get orthogonal point coordinates. Nothing more. How they do it depends on the ease of use of the system, the accuracy needed, the field of view size, and the desired resolution of the data.

White Light 3D Scanners

These systems are range from the lower end introductory systems to the highest resolution systems on the market. All of these 3D scanners project some pattern of white light on an object and take pictures of the pattern extracting the orthogonal coordinates of the surface. For the most part, these systems will be very dependent on the type of part used and the vibrational stability of the environment. Unless you are need of very high resolution, these scanners are best in environments for reverse engineering and a need for texture is also important to capture.

Laser 3D Scanners

Laser systems have evolved to a point in the last 10 years that they are the most versatile and easiest to use. Newer scanners can typically scan any surface that light can reflect off, even mirrored or dusty glass surfaces. In their most basic form, they work the same way as white light 3D scanners, but instead of projecting a pattern of light, they project laser lines. The more expensive scanners will project multiple lasers simultaneously and are able to obtain millions of data points a second.

General CAD FAQ

I need my project done today or tomorrow. Can you process rush jobs?

Depending upon when you catch us, yes, we can handle rush jobs. We often work over the holidays, Thanksgiving and even Christmas holidays. If you have a deadline – call us.

For years we have run three shifts of about 30 drafting folks per shift – allowing us to deliver work 3x faster, and seven days a week. Yes, we work 24/7, so you do not have to. The fun never stops here.

For 3D scanning, this is a different question. Because of the common setup work required, at best expect a 48-72 hour turn to be scanned. CAD or simulation services are in addition to that.

Who is affected by the PPD-21 directive?

The Department of Homeland Security has identified 16 different infostructures:

  1. Chemical Sector,
  2. Commercial Facilities Sector,
  3. Communications Sector,
  4. Critical Manufacturing Sector,
  5. Dams Sector,
  6. Defense Industrial Base Sector,
  7. Emergency Services Sector,
  8. Energy Sector,
  9. Financial Services Sector,
  10. Food and Agriculture Sector,
  11. Government Facilities Sector,
  12. Healthcare and Public Health Sector,
  13. Information Technology Sector,
  14. Nuclear Reactors Materials and Waste Sector,
  15. Transportation Systems Sector,
  16. Water and Wastewater Systems Sector.

This is both Government and private sectors.

If you are in any of these industries, this directive is important to you for many reasons.  Do you know where your critical sections are? Are they well protected? Are there concerns for Hazmat, security clearance requirements, and other concerns?  Can you quickly rebuild what might be lost? 

The important part of this means that critical infrastructure must be secure and able to withstand and rapidly recover from all hazards. Achieving this will require integration with the national preparedness system across prevention, protection, mitigation, response, and recovery.

Further details can be found at:  Government PPD-21

DHS – The National Infrastructure Protection Plan details:  The National Infrastructure Protection Plan

Industry specific plans:  2015 Industry specific PPD-21 plans

CAD / CAM Services provides PPD-21 for the following industries:  DHS – CAD / CAM Services

What is the PPD-21 Protocall?

The Presidential Policy Directive 21 (PPD-21) is a Critical Infrastructure Protection and Resilience United States directive that aims to strengthen and secure the country’s critical infrastructure.The goal of this directive is to reduce vulnerabilities, identify and disrupt threats, minimize consequences and hasten response and recovery efforts related to critical infrastructure.

The directive defines resilience as the ability to prepare for and adapt to ever changing conditions, terrorists, and withstand and recover rapidly from disruptions. Resilience includes the ability to withstand and recover from deliberate attacks, accidents, or naturally occurring threats or incidents.

Do you support the PPD-21 Directive?

Yes we do, and have now for several years. In addition, we also support the industry specific plans as well.

Did you really own the trademark Cad Perfect™, Cad Perfect CAD Conversions™ and Cad / Cam Services™?

Yes, we did back in 2008. We started using Cad Perfect™ back in the early 1990s because all of our customers wanted only real Cad Perfect™ work. Back then the buzz words were terms like machine ready, or DXF Traceover and others.

The problem is, nobody wanted that. They all wanted drawings and models that they did not have to touch. Everybody wanted drawings just as if they hand redrew the work themselves.

Thus, Cad / Cam Services™ was the first company to start offering ONLY Cad Perfect™ work. 

What is the estimated delivery time?

It depends on the scope of work:

  • 2D drawings – small quantity, normally 48 hours.  We have several customers where they contract to us, keeping 4-8 drafters busy full time.
  • 3D models – complexity dependent, but smaller jobs in 2-3 days. Some models we have spent months on.  Again, we have several customers where they contract to us, keeping 6-10 3D CAD designers busy full time.

Simple jobs have a lead time of 48 hours. Larger projects are delivered and invoiced weekly.

Will CAD / CAM Services Sign a Non-Disclosure Agreement (NDA)?

Yes. NDAs are a common part of our business. All data is yours – not ours, and treated as proprietary data and not for public consumption or use. Probably 70% of our work is under NDA agreements. We can generally get these signed within the day.

How do I send a sample, in order to get a quote?

Fill out our quote form, attach your files, or simply send us an email. Tell everything about your project, like the model purpose.

For smaller files < 15 MB you can simply email them to us.  For something larger, just drop them in any number of drop boxes like Dropbox, Google Drive, Microsoft OneDrive and others.  Or if you would like, just contact us for a private, hardened link.

It is fine to use most any time of compression such as  *.zip, *.rar, *.tar, *.7z, *.arc, *.LBR, and even *.iso images.

A direct email is [email protected]

We also use a hardened OwnCloud web file sharing platform for unlimited file transfers. We provide unique and very private Web Storage Portals, this also supports file syncing for extreme convenience for you. Because so much of our work is DOD or weapons design work, Security – and confidentiality is very important to us.

3D Scanning FAQ

Can you scan the internals of my parts?

Depending on the situation we can offer you dissecting your part for scanning purposes or use CT if applicable.

What is the minimum price for your scanning services?

For 3D scanning services our minimum order fee is $120.

How good are your 3D CT scanners?

  • 4 to 400µm/voxel resolution
  • Full inspection of large size samples
  • Modular and micro-resolution capability
  • 6 motion axis

Can your scanners find voids in materials?

Yes. This is one of CT scanners’ major points – to see into objects. This is the best solution for nondestructive quality control.

Do you support CT scanning?

Yes with both the DeskTom and EasyTom CT scanners.  They both support metrology grade Computed Tomography (CT) inspection.  This provides nondestructive, 3D Scanning of Internal and External Geometries.  We use the Volume Graphics VGStudio Max high-end industrial CT software for the demanding of CT applications.

How accurate is 3D scanning?

The scanners we use are as accurate as the industry offers – from anybody at any cost. We use Faro and Artec 3D scanners, in addition to Faro CMM type arms, including the Surveyor tables. Depending on what scanner we use:

  • CT scanners – 4 to 400µm/voxel resolution
  • Artec Portable scanners high accuracy (0.03 – 0.05mm)
  • Artec Portable scanners high resolution (up to 0.15mm)
  • Our CyberGage 360 – generates highly precise full 360 degrees automated scan with accuracy NIST traceable to approximately 7 microns
  • The CyberGage 360 has a system repeatability of ±.005mm.

What types of scanners do you use?

  • Faro Arm – Very good for most parts, fast and accurate
  • Turntable scanners – high accuracy, high detail, fast scanning. Great for smaller parts.
  • Portable handheld – may be favorable for some larger parts – if not a tripod-mounted scanner.
  • Long Range – these mount on a tripod, and are intended to scan buildings, plants, and other larger sized projects.
  • Industrial CT scanners – incredibly expensive, but they offer two main benefits – the ability to inside an object (think of a void in a solid object), and their accuracy.  At this level, we are often in the ±.001” – ±.002” range, and often used in metrology scanning.

What is the Point Cloud/Mesh/3D Scan?

A point cloud is thousands if not millions of data points located in space by X, Y, Z coordinates. Images of this nature are often captured with Faro Focus or Artec scanners that specialize in large-area scanning.  Most likely you obtain building and territory plans in this file format.

A polygon mesh is a set of triangles located in the same manner. These scans are obtained with Artec, Creaform, Enscan and other handheld scanners. Parts and reverse engineering device scans are usually polygon meshes.

How much does scanning services cost?

It depends on the complexity of the scanned model and material properties. As, for example, it may be much more complicated to properly scan an object with a reflective surface, than a non-reflective surface. It also depends on three main factors:

  1. the physical size of your part
  2. the required scanning resolution
  3. if industrial CT or metallurgy scanning is needed

Simple quick cell phone photos are worth a thousand words to us. To know for sure you can request a quote. It is of course, free – and treated as if an NDA is already in place.

Some averages:

  • The typical 3D scan is somewhere around $200-400 per part.
  • Tomographic (CT) scanning is $600-900 per part.

Because so much of our business is Aerospace related, our scanning – and the completed CAD file HAS to be within ±.005” anywhere on that part, we never use consumer-grade scanners. The scanners we use start at $25,000 and go up to $700,000 (CT) per scanner.

At any given time, we have in excess of $ 5 million just in scanning hardware we use. In addition, a hidden factor of scanning on any system is the assembly and clean up of any scan. The rule of thumb is a 2-1 ratio. So even with our experienced scanning staff, if we spend one-hour scanning; we will then spend an additional two hours of clean up and assembly before our CAD group gets the Point Cloud file to simulate or reverse engineer.
