List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Prepare object to be scanned | 1.1 Size and complexity of the object to be scanned is determined 1.2 Output requirements of scan are determined from specifications and confirmed with client 1.3 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 1.5 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 2.2 Any malfunctions are reported to relevant personnel for repair or maintenance in accordance with organisational procedures 2.3 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 3.2 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 | 4.1 Scanner files are downloaded to computer 4.2 Data and images are checked to confirm quality meets client specifications 4.3 Scanner output files are converted into the specified file format 4.4 Data files are presented to the client to confirm specifications have been met |
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.
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.
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the printing and graphic arts field of work and include access to:
a 3D model
a 3D scanner
specifications for scanner output files
organisational and manufacturers' operating procedures.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
