Elements and Performance Criteria

1. Prepare object to be scanned
   • Size and complexity of the object to be scanned is determined
   • Output requirements of scan are determined from specifications and confirmed with client
   • Appropriate scanner is selected to suit the type and complexity of object to be scanned
   • 1.4 Object is surface treated according to the scanner's operating requirements
   • Object is oriented for the most efficient scan
2. Prepare scanner
   • 2.1 Scanner is checked and adjusted in readiness for operation according to manufacturer's operating procedures
   • Any malfunctions are reported to relevant personnel for repair or maintenance in accordance with organisational procedures
   • Tolerance level of the scanner is set to achieve the most effective scan that meets client output specifications
3. Operate scanner
   • 3.1 Scanner is operated efficiently according to manufacturer's operating procedures and the organisation's work health and safety (WHS) procedures
   • Scanner settings are monitored and adjusted to ensure an effective scan
   • 3.3 Scanner files are retrieved according to manufacturer's operating procedures
   • 3.4 Scanner is shut down and reset according to organisational and manufacturer's operating procedures
4. Prepare output file ready for end user
   • Scanner files are downloaded to computer
   • Data and images are checked to confirm quality meets client specifications
   • Scanner output files are converted into the specified file format
   • Data files are presented to the client to confirm specifications have been met

Performance Evidence

Evidence of the ability to:

communicate with client to ascertain needs

determine scan requirements from client specifications and object criteria

select an appropriate scanner and prepare the surface of the object

prepare the scanner and orient the object effectively

scan the object safely and efficiently

create files from scanner to client specifications.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

Knowledge Evidence

To complete the unit requirements safely and effectively, the individual must:

describe the common three-dimensional (3D) scanner technologies and their respective applications

evaluate a range of objects to be scanned and select an appropriate scanner and the treatments to be applied

list and describe current industries where 3D scanning is used

identify the safety requirements when using 3D scanners

explain the importance of adjusting or considering scale, units of measurement, calibration, distance from subject, tolerance, and resolution for efficient 3D scans

specify the output file types for various applications, including but not limited to, the following file extensions:

STL - standard triangle language/standard tessellation language file format

OBJ - geometry definition file format

PLY - polygon file format

VRML - virtual reality modelling language file format

XYZ/PTX - point cloud file formats

AMF - additive manufacturing file format

describe the file conversion process required to prepare files for various applications.
