It took the manufacturer more than two years to develop KSCAN20, with colossal efforts pouring into the improvement of the scanner’s performance so that it fully corresponds to the customer requirements and expectations. 

The principle of operation is based on a combination of double laser scanning, which ensures high efficiency and an unprecedented level of detail, as well as an integrated photogrammetry function that remarkably expands the scanning area and sharpens volume accuracy.

What sets this 3D scanner apart from others is its unique ability to measure objects from 0.02 to 10 m on each axis, which makes KSCAN20 applicable to various branches of industry.

ScanViewer is a free, multifunctional software solution by Scantech meant to maximally simplify the utilization of their 3D scanner. 

This software can be used at all phases of a production cycle: development, design, and product quality inspection. The obtained data can be used for rapid prototyping, reverse engineering, 3D-displaying, etc.

The GD&T function allows users to directly create and analyze objects, take measures, and determine deviation values based on the data gained through the scanning process.

The KSCAN20 is a far more accurate and versatile scanner and can rightfully be considered a game-changer in the field of portable 3D scanning.


Case study

Quality control during aluminum die-casting

Let’s speak about case studies of the KSCAN20 3D scanner in different industries, precisely for the quality control of die-cast aluminum products mentioned on the Scantech website.

Aluminum die-casting is prevailing in machinery manufacturing but also used in other manufacturing areas such as the automotive industry as well as the production of electronics and domestic appliances. 

The process of aluminum die-casting has many nuances, while the quality of finished commodities must comply with numerous standards. This forces the manufacturer to know the exact dimensions and the accurate deviation values in order to identify errors timely and prevent the release of poor-quality products. 

The main purpose of the quality control policy in such industries is deformation prevention; and to ensure this, it is necessary to assess different factors including the structure, rigidity, and roughness of the output products. A powerful 3D scanner is a perfect solution to solve this problem.


The scanning process

Stage 1: the attachment of markers (the number of markers is twice as little compared to the use of normal handheld scanners).

An aluminum detail with dimensions of 200 × 200 mm was used for this experiment.

Stage 2: scanning both sides of the detail with a blue laser.

Real-time visualization 

Stage 3: the obtaining of the full 3D point cloud data using ScanViewer (the picture depicts the front side of the detail).

Stage 4: the calculation of deviation values (the front side).

The top-notch KSCAN 3D scanner dramatically cuts down the scanning time thanks to very few markers. The whole process from the attachment of markers to the report generation took no longer than 16 minutes.


ThinkSmart, the auto service

The Vietnamese company ThinkSmart developed an intelligence system of the production of body parts to repair different vehicles. Using the KSCAN 3D scanner and SLA 3D printing, the company gets a virtual model of the necessary part, then transfers it to the 3D printer and receives the desired, ready-to-use detail made of ABS plastic.

The use of KSCAN together with SLA allows for high printing accuracy, while the properties of ABS plastic ensure that the obtained detail is durable and resistant to heat.

Thus, a small number of car body parts can be produced at a significantly lower cost compared to the aluminum die-casting technology.
