Most common Materials used in 3D Printing

mayo 28, 2015 Inés Jiménez

The use of eco-friendly materials which are the ones that strive to reduce the manufacturing carbon footprint and reduce the subsequent effect on the environment such as is the case of recyclable and biodegradable materials is still one of the biggest challenges in materials science today. Moreover, materials scientists are also looking out to reduce the effect on human health which is also a big challenge no only for the health industry but for people’s general wellbeing.

Thermoplastics of interest to the engineering and design industry

Although Policarbonate (PC) and Nylon are very popular materials within different industries, Polyacrylate butadine styrene (ABS) and Polylactic Acid (PLA) are thermoplastic polymers of great interest to the engineering and design industry today.

ABS is one of the most used polymers in the market. Although the manufacturing process of ABS is more complex than more common polymers such as polyethylene and polypropylene it desirable and effective in the auto and domestic appliances industries due to its mechanical properties, and therefore it is know as an engineering polymer. Without going too far, the famous lego pieces are made out of ABS.

On the other hand PLA is a polymer made up of lactic acid, and as of today it is the most popular biodegradable and biocompatible polymer in industry. Most of the PLA produced worldwide is used for household applications such as clothing, bottles, cups, and food packaging. PLA is sought the be the best replacement for petroleum based polymers with the added value that PLA has a low impact on the environment and are biodegradable.

Another great characteristic of PLA is that it does not cause harm to the human body and therefore has been used and studied by the health and bioengineering industry. The mechanical and the biocompatibility properties of PLA make it an ideal substitute for bone and soft tissue, such as for maxillofacial trauma, orthopaedic surgery, ophthalmology, orthodontia, controlled release medical implants and resorbable sutures such as the ones used in eye, chest and abdominal surgery.

Biocompatible Resins for the health industry

Photo activated polymerisation is the process of which a polymer is cured with the presence of UV or visible light, depending on the additive that is used. The base of a photopolymeric or photocurable resin is an organic polymer which has a photoinitiator, a compound/additive that initiates the polymerization reaction. This photoinitiator is consumed during such reaction. Via  the presence of “absorption additives” radicals are released when exposed to specific ranges of wavelengths which initiate polymerisation. In layman terms, the polymeric resins hardens when exposed to certain wavelengths of light. In the 3D printing industry these wavelengths tend to be within the UV or visible spectrum.

Materiales utilizados para impresión 3D

El empleo de materiales ecológicos que permitan una reducción de la energía necesaria para su procesado, sean reciclables y biodegradables (en el caso de que finalmente sean desechados) y no sean dañinos para la salud humana y la del medio ambiente, supone un reto para la ciencia de materiales en la sociedad moderna. Termoplásticos de […]

Inglaterra en InMateriis

agosto 1, 2017

Desde septiembre, con pauses entre ese tiempo, se han escuchado los claros acentos británicos en las oficinas de inMateriis de los dos nuevos integrantes al equipo: Alan Joseph Parish y George James Brodie, llegados directo desde la Gran Bretaña. George es proveniente de Londres–aunque haya crecido a las afueras de la ciudad. Consiguió su licenciatura […]

InMateriis at #CampusPartyMX7!

agosto 1, 2017

The Jalisco Campus Party is a yearly event, with the purpose of gathering the technological talent and entrepreneurship in the country through workshops, stage events and more the 700 hours of content with over 20,000 “campuseros”—the nickname for those that attend to the event. It was in June 30th that the team of @inMateriis arrived […]

Los biomateriales y la medicina

noviembre 18, 2015

Desde tiempos remotos, en diferentes culturas se ha estudiado el uso de materiales que puedan ayudar al ser humano a la restauración de las funciones de tejidos dañados y el aprovechamiento de estos para una mejor calidad de vida. Desde el uso del oro y la plata para reparaciones dentales en el siglo XVI, pasando […]
