The process of 3D scanning encompasses many technologies which create an accurate surface of points which can be used to measure, compare or create a 3D model from.

3D scanning is a problem solver for many applications. It provides measurement data of complex shapes, insurance for rare objects and can be used to inspect something against reference data.

Although it saves time and money in most applications, it isn’t ideal for every job. Some things can be modelled or recorded just as quickly and easily using traditional metrology equipment and it doesn’t have the achievable accuracy required for others. We are always happy to look at your project and say whether it warrants scanning, or if there is a better way to achieve the desired result.

We utilise our own Faro Quantum S HD Scanarm, CMM scanners from Nikon and High accuracy Surphaser long range scanners. When appropriate we will hire other systems to assist on specific jobs but we have most bases covered.

For scanning, alignment and clean-up we use Polyworks and Geomagic Wrap. For Inspection work we use  Polyworks Inspector, Geomagic Control and Geomagic Control X. For reverse Engineering we use a vast array of programs, but mainly Spaceclaim with Geomagic Capture and STL Prep plugins and Geomagic Design X. To render we use KeyShot and for 3D printing we use software from 3D Systems and Simplify3d.

3D scanners are just one of the tools at our disposable. We have a vast metrology collection including a CMM’s, portable CMM’s, laser trackers, height gauges, bore micrometres, plug, thread and ring gauges, and much more.

Usually we deliver scan data in the universal formats of .STL or .OBJ.

Reverse engineered solid models are usually delivered as a STEP or IGES, though we can import and export most formats if required.

Our data is able to be opened and used in nearly all CAD packages including Solidworks, CATIA and those from Autodesk.

When introducing 3D Scanning, it can often be hard to explain what the available data options are and what can be done with that data. Here we aim to put across a clear overview of the different data types available, along with downloadable examples so you know exactly what you are going to receive and what you can expect to be able to do with it.

Probed Data

Probing can be a great tool for analysing geometrical entities, for mapping out complex layouts and as a supplement to 3D Scanned Data.

When an object is properly fixtured, probing has an even greater accuracy than scanning and the data is much easier to use in CAD software, for people without the experience of working with meshes.

Planes, cones, holes and much more can be measured using probing.

Point Cloud Data

Point clouds are a collection of individual 3D measurement points created by a 3D scanner. Each one represents an individual position in the 3D Co-Ordinate system. Depending on variables such as scanner resolution, speed and project size; a point cloud can be millions or even billions of points.

Point Cloud data is the rawest form of data. It is particularly good for inspection work and while working with large projects, such as building scans. Only certain job specific programs can import point cloud data successfully.

Polygonal Mesh

Polygonal Meshes are a step on from point cloud data. Here the points have combined to create a mesh of connected triangles. This is how we usually deliver 3D scanned data.

Meshes are used in many fields such as artistic modelling and archiving. They are also the basis for most reverse engineering applications. Watertight meshes (where no gaps are present) are the model format for 3D printing and can be used by some software for freeform machining.

Different CAD software deal with meshes in different ways. The majority can import them but they offer differing levels of usability. Most allow you to at least see it and use it as a form of template for your modelling. You can put planes through the mesh, sketch around the shapes and extrude through them. Some programs will also allow you to snap to the mesh itself, and some will also offer the ability to select a portion of the mesh, and best fit for instance, a cylinder or freeform surface to it.

NURBS Surfaced Models

Non-Uniform Rational B-Spline Surfacing can be a great way to model complex freeform geometries or just to quickly turn polygonal meshes into a more standard format.

These can be imported into a CAD package and used to manufacture from. NURBS can be notoriously difficult to edit however, and if taken directly from scan data, will carry all of the defects from the original part. We can work with you to achieve the required results.

Solid Models

A solid model is a three dimensional model which can be defined by specific dimensions and geometry.

These can be opened in nearly all CAD programs, can be used as the basis for all manufacturing and are generally, easily editable.

We can design these exactly as you require: whether you want the model exactly matching the one provided, it created with design intent (to correct imperfections) or with any design changes you need.

Machining Drawings

Machining drawings can be created from partial or complete models for the required purposes.

We can also use provided drawings to convert to 3D, check tolerances or add missing features.

We can use either portable storage or online file servers to deliver data.

Using data provided by others isn’t usually a problem. We are happy to offer a free consultation if you can provide us with the data and what you are looking to do with it.

www.wetransfer.com is a good way to send large data files.

We have scanned yachts, aeroplanes and buildings.

Most of our scanning systems are completely portable so we are happy to scan either in our premises or at yours.

These portable systems can run off battery power so we can even scan in remote locations.

We use non-contact scanning systems so there is little to no risk of damaging your parts during the scanning process.

Our largest printer has a build volume of 700 x 700 x 1800mm. We can print some parts which are longer than this in one go by printing them diagonally. We can also print parts in multiple parts and bond them together.

We’re happy to discuss the best material and technology for your application. If you’re local to us you are very welcome to come in to see and hold examples.

We 3D print using .STL polygonal mesh files. We can however accept most solid or mesh file formats (.obj, .step, .iges, .sldpart, CATPart etc.)

Absolutely. Using our reverse engineering or design services we can help create your file ready for 3D printing or any other CNC based manufacturing process.
