Luis Germano - Expert Opinion 4

Born in Almoster, Santarém in 1974, Luís graduated in Mechanical Engineering (Production field) in 2006 from IPL.
After 10 years working as a designer and later as an engineering draughtsman, in 2003 Luís began working in Project and 3D Design as a freelancer, providing consultancy to multiple companies.
Technical drawing, CAD and CAm trainer at CENFIM Santarém since 2012.
Working at TEPSOL since 2002.
BEEVERYCREATIVE’s BEEagent since 2014.
Luís is currently taking training in welding engineering at ISQ.
On a personal level, technical drawing and 3D printing are two of his passions, which he regularly works on. He has other areas of interest like photography, technology, cinema and travelling.

What do you think of 3D Printing / Additive Manufacturing and its potential?

3D Printing / Additive Manufacturing will grow a lot, I have a very optimistic opinion about the importance it will have for most companies, expecting a considerable growth in the next few years. With the accomplishment of having 3DP dedicated departments, the evolution in polymer materials will leverage this evolution, as well as the usage of metals and ceramics. This material diversity has a direct impact in the physical, chemical and mechanical properties of the parts made.
The dimensional and geometrical quality of the parts, as well as the state of the surface is essential. The bigger the quality 3D Printing brings, the bigger the acceptance of 3D Printing by the industries.
In the rapid prototyping process, 3D Printing is one of the best tools we have available nowadays.
In the future, in the next 50 to 80 years, author Michio Kaku foresees that 3D printer resolution reaches an atomic level, capable of printing with multimaterials, with high resistance so that the 3D printed pieces can be functional and higher speeds, which will allow for functional parts and higher speeds, able to replace cutting tools in many situations.

What is the main impact of this technology in society, training and for companies?

In 3d printing, the manufacturing waste is almost non-existing. That represents an amazing positive performance in terms of environmental impact, which contributes to a cleaner and more responsible society. The economical factor is also very important in 3D Printing, as it allows savings in obtaining parts, with shorter production time, more flexibility in altering parts.
Personally, I use 3D Printing to create didactic models, for rapid prototyping of a lot of day-to-day objects. The society of the future will be based on on the idea of “proconsumer”, which means the consumer produces its own parts.
The ease of use and speed in the project development puts the companies who use 3D Printing at the forefront of competitivity. In training, 3D Printing enables people to create objects, enhancing their creativity.
I have always been trying to find ways to combine 3D Printing and the Industry and I have several experiences where the investment in 3D Printing translates into an immediate and unquestionable return on investment.
Inside the companies, choosing the right team is essential to the success. It is very likely that companies searching for employees with 3D modelling experience will choose candidates who also have experience with 3D Printing.
The MAM system (Metal Additive Manufacturing) is being announced as a guide to the traning of technicians for companies, the release date for it is the end of 2018. Industry 4.0 presents this area as fundamental to the skills necessary to its implementation.
Within the MAM system, there are also considered SLM (Selective Laser Melting), DED (Direct Energy Deposition) and WAAM (Wire Arc Additive Manufacturing). For all these systems, there are two professional levels: operator and engineer. This will be the strategy used to connect training and Industry.

With the introduction of 3D Printing in training, what were the challenges faced? What changed? What improved?

Training in 3D Printing had helped to enlighten the ones interested in this topic, in their questions about the technology, allowing them to learn, test and practice the first contact with existing models. 3D modelling and 3D model handling is common to all industries and manufacturing technologies. We can get training in a portable desktop 3D printer and then work with an industrial and sophisticated 3D printer, since they both have things in common. This advantage allows you to have 3D printers in the classroom to demonstrate.


What is the relationship between the trainees and 3D Printing? What impact does this technology have on their training and their professional future? 

3D Printing captivates people, inspires and motivates from the youngest to the oldest, barely anyone is indifferent to it. Most trainees embrace 3D Printing with enthusiasm. 3D Printing training promotes ideas, entrepreneurship and the creation of new products. The main idea here is PERSONALIZATION, each piece has a personal touch.
In training, it is very important to ally 3D Printing with technical drawing. With technical knowledge about 3D Printing, 3D printers and technical drawing, you can get amazing results.
Knowledge is power. Nowadays people who know how to 3D model will quickly go from digital models to real models, thanks to CNC machines, whether it’s cutting tools or additive manufacturing (3D printing). Technical drawing training is fundamental to improve the quality of the projects and therefore, the quality and functionality of the parts.

What is the main use of 3D Printing for your projects?

In projects, the priority is often 3D Printing for the fabrication of parts because of the ease of use. We only chose fabrication in CNC and other conventional methods when 3D Printing is not suitable, due to the need of bigger dimensions, type of material or mechanical resistance.
The 3D printers we have at our disposal for the projects have some limitations that restrict their use. However, recent news about Fabrication of bicycles with DED, for example, are very promising. This shows the very significant advances made in the quality of materials. The same goes for components in the aerospace industry.
When you combine 3D Printing and technology in a way to physically support components such as sensors, cameras, motherboards, etc…, you can get very satisfying results.

Do you think the Maker movement is important for the adoption of this technology? Why?

The maker movement has many strengths, amongst them is the “creation”. The fact that it involves constantly creating 3D models for 3D Printing, testing and sharing them, creating libraries of thousands of models, often free, that allow 3D printer owners to access to a global scale library. There are thousands of models available for download at online galleries.
The Maker movement creates a global knowledge, an exchange of ideas. Forums are a valuable tool for everyone who wants to solve a problem. The future libraries will be the “FabLabs” and “Makerspaces”, places where 3D Printing is always available.
