Questions about quality Quality - Only the best for our customers

With the advent of computed tomography, we are investing in the latest and best possible technology for capturing three-dimensionally generated products in both prototyping and series production of plastic parts. The latest generation of computed tomography systems from Wenzel enables three-dimensional recording and display of the accuracies required in component drawings. This means that they can also be tested in the generated component in the best possible way. We see the introduction of this technology as a milestone at 1zu1.

We ensure their quality by using various measurement techniques such as 3D scan or computed tomography. Starting in 2022, at least one manufactured component will be scanned with a newly acquired CT device after each production process and the manufacturing tolerances will subsequently be evaluated. 

A key feature of surface finishing is the ability to give models and prototypes additional functions. For example, the surface can be protected against corrosion, and further enhancements can be made in terms of temperature resistance or durability.

Another advantage is optical refinement and thus the improvement of aesthetic and decorative properties. At 1zu1 we offer the following methods: infiltration, polishing, tumbling, printing, laser marking, vapor deposition/metallization, hot foil stamping and heatset impregnation.

In a short time, the measurement results for each scanned component are available with an accuracy of up to 0.005 mm – depending on the size and density of the component. With the help of color comparison images, you can immediately detect any deviations between the original data set and the component over the entire object. Complex individual measuring points can be omitted, but are possible at any point. This allows a decision to be made immediately as to whether deviations are still acceptable or already outside the requirement. In other words: quality control at a glance.

A complete three-dimensional image of the scanned object can be created. Measurements can therefore be made retrospectively at any point on the component – without the need for an actual component. This provides security for measuring points that are not even known at the time of the test report, even if the component is no longer available. STL data is archived at 1zu1 free of charge and it is possible to perform another or a new test at any time.

Additional individual measurements, such as shape-position tolerance, parallelism, coaxiality, distances, cuts, etc. enable measurements at any point. The results can also be output in tabular form just like tactile measurement protocols.

Comprehensive measurement data is even possible for painted components, glossy surfaces and sharp edges.

From tiny electronic components to small objects and large models up to 150 x 300 mm made of plastic – anything is possible.

Full 3D capture and comparison with the original 3D data model enables real-time analysis between target and actual. Comparison images quickly and clearly reveal any deviations in terms of dimensional accuracy, distortion, sink marks or spring-back of sheet-metal parts. A color comparison of the 3D scan (“actual”) to the original CAD data set (“target”) enables a quick assessment of deviations and distortions.

It is used in quality assurance, product development and production alike and is used to measure industrial products, engines, machines and components, electrical and household appliances, consumer items, etc.

In this method, optical 3D scanners measure without contact using optical sensors. A stereo camera system is used for three-dimensional measurement and shape measurement. Complete 3D data of large and complex components are captured. 1zu1 uses the Atos Triple Scan 3D scanner.

Optical metrology is used to determine physical quantities with the aid of various devices. It is indispensable in automation technology, as it monitors the quality of the product in the form of measurement and test data during the product creation process.

We monitor the entire market and continuously test new processes, materials and improvements to existing technologies.

Around five to ten times per year we inform our existing and prospective customers about the latest innovations at 1zu1 Prototypes. We will be happy to provide you with this information – you can sign up for our newsletter here.

1zu1 is the first company in Austria – and the third in the German-speaking countries – whose quality management has been certified in accordance with the new ISO 9001:2015 standard via an audit by DEKRA.

We offer a variety of surface technologies such as printing, painting, vaporizing, chrome plating ... -> learn more here.

The quality levels Economy (EC), Business (BC) and First-Class (FC) are only available for stereolithography technology (STL) and describe the surface quality with or without construction layers.


The available surfaces for the respective technologies can be found on the technology pages – at the bottom under the “Surface technologies” tab.
