Application
This unit describes the skills and knowledge required to assess and rectify manifold errors and convert graphics files to a usable format for three-dimensional (3D) printing.
It applies to individuals with higher technical skills in 3D printing technologies who provide 3D printing services to internal or external clients.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Assess image quality | 1.1 Graphics file is received and requirements for precision, quality and materials are determined from specifications and confirmed with client 1.2 Graphics file is assessed to select software required to perform adjustments 1.3 File is opened and faults, imperfections and manifold errors are identified against client specifications 1.4 Time and cost of work required to rectify identified faults, imperfections and errors are calculated 1.5 Client is informed of work requirements and approval obtained for planned work |
2. Prepare a precision 3D print file | 2.1 File is manipulated to remove imperfections and manifold errors 2.2 Output file is prepared according to specifications 2.3 Graphics file quality is reviewed with client and sign off is obtained 2.4 File is saved in a format appropriate for 3D printing |
Evidence of Performance
Evidence of the ability to:
communicate with client to ascertain needs
confirm client requirements for three-dimensional (3D) print output
determine work requirements and obtain client approvals
recognise faults, imperfections and manifold errors in 3D printer files
use software to rectify errors in 3D printer files
save files in required format.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
describe the common manifold errors in 3D printer graphics, including the effect on:
proposed printed material
printing technology
wall thickness
file resolution limits
conversion between software
support structure
explain the relationship between 3D graphics modelling software and 3D graphics image software, including:
file types
function of the software
main image editing tools
scale and units
describe "Cartesian coordinate system" and how it relates to 3D graphics file manipulation
describe the purpose of "slicing" in the preparation of G-Code for 3D object build
describe the effect of setting resolution and deposition thickness in 3D graphics on 3D print output quality.
Assessment Conditions
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 pre-media field of work and include access to:
a range of graphics model files and graphics image files with errors
a computer with industry-standard 3D graphics software packages
a 3D printer or 3D printer specifications.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
