Design and 3D Printing of a Functional Prototypical Tank in Polyamide

Printing Material: Pa2200 / Polyamide

Prosilas has leveraged the capabilities of additive manufacturing to design and 3D print a prototypical and functional tank in PA2200 intended for laboratory testing or trials.

This tank is engineered to contain corrosive liquids such as gasoline, diesel, ethylene glycol, brake fluid, and ATF.

Un serbatoio funzionale realizzato con il materiale PA2200/poliammide, inizialmente progettato come prototipo per test di laboratorio e collaudi, è stato successivamente incorporato nel processo di produzione. La sua progettazione mirata lo rende adatto per il sicuro contenimento di liquidi corrosivi come benzina, gasolio, liquido glicole-etilenico, liquido freni e ATF.

What is polyamide?

Polyamide  (PA2200) is a 3D printing material commonly known as Nylon, used with Selective Laser Sintering (SLS) technology.

Characterized by excellent mechanical and chemical properties, it complies with biocompatibility standards. It is employed in manufacturing of components and medical devices and industrial parts, and in the automotive industry.

Its versatility in SLS printing makes it suitable for mass production. Printed parts can undergo various finishes, such as metallization and painting.

Custom Functional Finishing

To ensure a personalized functional finishing, Prosilas has implemented a waterproof surface treatment.

This treatment has been developed to seal the microporosities of polyamide, eliminating the release of dust particles commonly associated with SLS artifacts, without altering weights and dimensions.

Validation, Mass Production, and “As-Built” Aspects

Following the thorough validation of the process and the optimization of the surface treatment, the application has entered mass production, enabling the production of an entire batch of tanks.

Thanks to advanced additive manufacturing technologies and new materials, Prosilas has achieved the creation of an “as-built” product, meaning it is ready for use without compromising functional aspects.

SLS Technology and Optimization of the Production Process

The adoption of Selective Laser Sintering (SLS) technology has enabled the creation of complex parts without the need for support structures, contributing to faster production times and reduced manufacturing costs. The production process has been carefully optimized to accommodate the part geometries and post-processing operations necessary to ensure the waterproofing of the final product.

Applications in Key Sectors and Materials Used

This innovative tank, developed at the Civitanova Marche facility, has been designed considering the specific needs of the automotive, motorcycle, moped, heavy-duty vehicle, heavy transport vehicle, and agricultural machinery sectors.

The material used for its construction is PA2200; tanks and similar applications can also be produced in Alumide, PA12 GF, PA2210 FR.

Furthermore, we provide customized finishes to meet any specific customer requirements.

Prosilas: “We help hospitals by printing spare parts for lung ventilators”

Prosilas: “We help hospitals by printing spare parts for lung ventilators”

Apr 27, 2020 | News Prosilas

A word from Prosilas during pandemic

Here the full article 

“Since the beginning of the pandemic we have made our work available to the National Health Service, pro bono”. Vanna Menco, Ceo Prosilas

“Vanna Menco, Ceo Prosilas, leader company in 3D printing, based in Civitanova Marche: “Since the beginning of the pandemic we have made our work available to the National Health Service, pro bono”. Requests for help from Lombardy, Marche, Sicily and France

Just go just below the surface, the seemingly immobile surface of a country closed in the “lockdown” forced by the pandemic, to discover that there are so many companies that, in silence and pro-bono, help hospitals to keep the front line of fighting the virus.

Prosilas of Civitanova Marche is one of these: from the beginning of the emergency has been at the service of the national health system, ready to meet the most varied requests, answering “just in time” and “on demand”.

 

The Marche-based company is a leader in Italy in addictive manufacturing and specialist in SLS laser sintering.

Simplifying for those who are not experts in the field, it turns out complete objects or parts, printing in 3D with different materials and various technologies both prototypes and small series productions for the major realities of the automotive and lighting industry, with large companies in industry, fashion, furniture and design.

 

Prosilas is the largest SLS printing center in Italy and one of the largest in Europe.

“As soon as we realized the gravity of the situation, we made an announcement on Ansa “- says Vanna Menco, Ceo of Prosilas sicne 2008, daughter of the founder Giulio Menco – “together with Francesco Puzello, the consultant who acts as a central point of contact for the network of companies with which we collaborate. We are available to produce spare parts for devices that are used in intensive therapies, from fans to adapters”.

Prosilas has been contacted directly by hospitals rather than the ALS“We have been contacted by doctors of hospitals in Lombardy –continues Menco -, those who are in the ward, asking us informally to produce some spare parts for pulmonary ventilators, about a hundred. Someone knew us, someone found us on the Internet. Or companies and designers we already worked with, who asked us for help for hospitals in their area”.

Prosilas and the research

It is not the first time that Prosilas has put itself at the service, with devices of excellence, of healthcare: at the end of 2019 it earned the headlines for having saved the life of a five-year-old child with a collapsed windpipe. Responding to the research launched by the pediatric hospital Bambino Gesù in Rome, Prosilas printed a customized stent, starting from a three-dimensional file extrapolated from a CT scan and using a biocompatible material, then absorbed by the tissues.

 

 

3D printing at the service of medicine

The Torrette hospital in Ancona looked for them because it needed adapters for oxygen flow-meters, spare parts that they could not find anymore, since the companies that produce them are struggling to manage the boom in demand.

Vanna Menco continues to list the territories that asked for help: “They called us from Sicily. And also from abroad, from France: our French customers ordered valves to deliver them directly to the hospitals in their country”.

Prosilas also collaborated with Cristian Fracassi, CEO of Isinnova, the 3D engineer who became famous because he invented the way to transform the Decathlon snorkeling mask into a respirator.

“In the world of 3D printing we all know each other, it is a small world, we have worked with many of our colleagues from all over Italy.If I may, I would suggest not to use too many so-called ‘makers’ – warns Menco -, non-professional printers, because it would jeopardise the safety of the devices. Humanly the enthusiasm with which they responded in many was wonderful, but the materials and processes used not certified could create problems. For now it has not been so, fortunately, but you have to be careful”.

The company of Civitanova Marche has remained open, even if in reduced ranks – 5 out of 18 employees still go to work – to finish some orders but above all to make itself useful to the sanitary, others follow in smartworking.

“This emergency does not end quickly. It would be appropriate to establish a more formal network at European level – she reasoned – among all the professional press centres.The problem of the parties is throughout Europe: it would be helpful for hospitals to have a contact person or a list to know which company is closest to which you can ask to print, since travel between countries is now almost interrupted”.

In the face of the emergency Prosilas works pro-bono, in the case of larger quantities reserves the right to ask for the costs of the material, in perspective, however, the health sector could prove one of the most promising, strategically looking to the future:

“Why not? We guarantee tracked and certified supplies. We had been investing for some time to increase production in the health and wellness sector”.
