3D Scanning & Reverse Engineering
3DTechnologies4U offers comprehensive 3D scanning services via our trusted network of specialists.
We can cover 3D scanning on items that require:
1) High accuracy and resolution (>0.05mm) such as jewellery, dental items, medical objects, small automotive and aerospace precision parts, legacy items etc.
2) Precision and excellent resolution (>0.1mm) such as glasses, medium automotive and aerospace objects, implants, miniatures, manufacturing tools, models etc.
3) For larger items that can’t be posted please contact us to discuss and arrange a 3D scanning service for you.
Are you ready to materialise your vision?
Why wait? Revolutionise your workflow now!
With 3Dtechnologies4U you have access to a large range of high-end 3D scanners for professionals or companies or entry level 3D scanners for simple modeling.
If you have a physical object which needs to be digitized into a CAD 3D model whether you want to remanufacture it or to inspect it, then feel free to contact us. We will gladly assist you.
What is 3D Scanning and what is its purpose?
3D Scanning is a process that produces highly accurate 3D point clusters from a physical object and converts the resulted digital image to a readable and usable 3D computer model.
It is the perfect technology to capture complex and challenging geometries that is impossible to measure accurately.
3D Scanning is used for the following three reasons:
1. To form and save 3D digital data of physical objects
2. To reverse-engineer items in order to re-manufacture them or 3D print them
3. To inspect and compare a manufacturing item against its original designed geometry
Along with 3D scanning services, we offer Reverse Engineering services to customers who would like to reverse-engineer a 3D CAD model and reconstruct an existing object.
Via our trusted network, we can 3D scan the item , and by using the digital file, we can produce a replicate component no matter the complexity, geometry or manufacturing method.
What is Reverse Engineering (RE)
The terminology is used to describe the digital process of re-engineering or replicate an existing physical part.
In ‘normal’ engineering, the design engineer will design an object as 3D using Computer-Aided Design system and by producing engineering and manufacturing drawings will be able to produce it.
In Reverse Engineering, the process starts from the existing component which will be 3D scanned and digitalised to a 3D computer model to reach the final destination of the manufacturing and product specifications.
Why we use Reverse Engineering
An object can be 3D scanned and Reverse Engineered for one or some of the following reasons.
• It is unique
• It has an extremely complex geometry
• It is a legacy object
• For parts that need to be remodelled and tested in order to demonstrate design optimisation.
• For analysing and inspecting competitors’ products
• For tools, jigs and fixtures manufacturing
• To analyse a defect component
The process of Reverse Engineering
A 3D laser scan is initially used to 3D scan a physical component while an accurate measurement system is needed to minimise the deviation between the captured data. This data will be interpreted to a digital point cloud positioned accurately into the space (specific software used). The point cloud combines 3D scans of the physical object using the same 3D coordinates, resulting in a 3D point cloud.
The latter will be soon converted to a very dense 3D mesh or even a full CAD model by specific software.
Starting from 3D scanning we can produce or reconstruct an object which is missing a digital 3D file. 3D laser scanning data is essential to reverse engineer an object. Most of the times, the 3D scan data need to be post-processed as the 3D scanner (using usually a DLSR camera) will not be able to capture deep apertures or the internal geometry of a part. As it is known, 3D scanners can only capture the outer surface of a component.Post processing the 3D scan data might be a long process and depends on the size and complexity of the targeted geometry.
