The 3D Printing and Additive Manufacturing Trade
Additive manufacturing is changing the entire process of product design and production. Rather than using traditional methods of cutting or machining materials away from a solid block, additive manufacturing uses a layered approach to manufacturing. This technology employs various materials, including plastics, metals, resins, or composite materials.
Technicians in the additive manufacturing sector need to know how to develop digital models, use printing machinery, and check if the prints meet the designated specifications. Therefore, in most settings, additive manufacturing technicians need to collaborate with engineers, machinists, and quality assurance personnel to aid in the production and prototyping.
The employee must be able to understand digital models and how to set and repair printers. It is also necessary for individuals to know the procedures, processes, and techniques for the safe use of materials, the handling of materials, and the post-processing that is done to the finished printed components.
Additive manufacturing is becoming more prevalent in many sectors, and the need for technicians who understand both digital manufacturing and manual production techniques is also increasing. For a closer look at hands-on industrial environments that rely on similar precision and coordination, you may find it useful to review how work is approached in mechanical production roles.
In the United States, training, apprenticeships, and pathways for starting a career in additive manufacturing are available.
In additive manufacturing, most practitioners have a background in technical education or training in manufacturing technologies, engineering, or digital fabrication. Many community colleges and technical schools that have recently opened in the United States offer courses on additive manufacturing, both theory and practice.
The training also covers computer-aided design (CAD), operation of printers, materials science, and quality control. Students are trained on how to adjust and prepare the machines for operation and how to control the machines during the production stages.
Some people most likely come into the industry through wider manufacturing apprenticeship or technical training programs tied to workforce development programs from the U.S. Department of Labor.
As new techniques emerge in additive manufacturing, workplace training and professional development programs are particularly beneficial for continual enhancement in skills. Those working towards certifications in additive manufacturing are likely to gain a deeper understanding of advanced manufacturing systems.

What you will find in the Assessments and Exams for Additive Manufacturing
If you are planning to conduct evaluations in additive manufacturing, you need to be prepared for both the theoretical and practical aspects of the evaluations. The theory side consists of evaluations and questions on various printing technologies, materials, design and production preparation, and workflow.
In the evaluation, you could be asked to respond to questions on printer calibration, layer adhesion, digital models, and machine maintenance. It is also of great importance to have a good understanding of the additive techniques involved in fused filament fabrication, selective laser sintering, or stereolithography.
As for the practical side of the evaluation, you are likely to be asked to download or create a digital file that you will prepare for printing, and then set up the machine to conduct the print, and then evaluate the print afterwards, and it is therefore important to show technical proficiency and great attention to proper quality control of the print.

Case Scenarios: New entrants versus seasoned professionals in additive manufacturing.
Scenario 1: New Migrant or Entry Level Candidate
A recent graduate or an early career professional moving into additive manufacturing from another technical field is an example of someone new to additive manufacturing. They might have some understanding of computer-aided design or general mechanical aptitude, but they will likely have little or no experience working with industrial 3D printers.
Some of the early challenges include learning how to do machine calibration, understanding the properties of manufacturing materials, and adapting to the production workflow pedigree typical of a manufacturing facility. Knowledge and familiarity with the relevant software and industry-specific jargon will also require practice and time.
Machine operation, fault diagnosis and quality control are areas within which entry-level technicians gradually develop confidence through the combination of technical instruction and practical experience. This is also the case with fault diagnosis and the control of quality.
Scenario 2: Professional in Additive Manufacturing with 10-20 Years Experience
Such a person has been engaged in professional practice in the field of digital fabrication technologies and more specifically, advanced manufacturing systems. However, when moving from one to another, perhaps more technologically advanced, sector, they may have to adapt to a whole new suite of printer technologies, different materials and a new production workflow etc.
It is the case, even for seasoned technicians, that the technologies in additive manufacturing are continually changing and therefore, in order to remain a technologist for any length of time, one is expected to do a lot of professional updating. This notion remains in an industry that is recognized as being fast changing.
It is also the case that many seasoned technicians are expected to assume managerial or leadership responsibilities in an advanced manufacturing system
