Silicone is used for 3D printing

- Apr 01, 2019-

Currently, materials available for 3D printing include resins, alloys (such as nickel-based chromium, cobalt, aluminum, titanium, etc.), polymers, ceramics, plastics, etc.With ACEO ® Imagine Series100, wacker has become * home by 3 d printing industrial production of the company.Before the revolutionary technology, silicone couldn't be 3d-printed.Today, * silicone has been used in modeling or small batch production, many industries benefit greatly.So what's so special about "* silicone" or "true elastomer" for the 3D printing industry?

Will be in the form of interview questions and answers below to share with you some of the German wacker ACEO ® experts team, Bernd Pachaly Dr For organic silicon materials applied in the 3 d printing technology insights, help all the mysteries of the organic silicon 3 d printing.

PhD in chemistry from the technical university of Berlin, post-doctoral research at the university of Wisconsin in 1984.Has many years of research experience in the field of organic silicon.In 1985, he joined the wacker chemical group.He has served as the director of core r&d department, the r&d manager of organic silicon business and the business team director of organic silicon engineering department.He took over the silicone innovation business in 2013 and has been in charge of the silicone 3D printing project since 2017.

Dr. Pachaly, what exactly is silicone?

A: polysiloxane is the general term for A class of polymers whose main chains are composed of alternating siloxane atoms.In this class of materials, silicone rubber is an important member, it is made of liquid silicone rubber or solid silicone rubber through a variety of cross-linking reaction.

Q2. ACEO ® is using which type of silicone?

A: ACEO ® is using liquid silicon rubber, the material by wacker is widely used in injection molding and is already well known.As one of wacker brands, ACEO ® benefit from more than 70 years of silicone professional technical knowledge, continuously develop this kind of organic silicon, to meet specific application requirements.

The main components of silicone rubber are silicone polymer, crosslinking agent, reinforcing filler and catalyst.It does not use any organic matter or copolymer, and the finished product is real rubber (* silicone), rather than "rubber-like" material.In addition, this cross-linking reaction is a platinum-catalyzed hydrosilylation reaction without by-products or residues.

Q3. How does * silicone compare to other types of rubber?

A: silicone has unique chemical and mechanical properties that synthetic rubber cannot match. For example:

Flexibility and elasticity

Weather resistance

Application temperature range is wide

Radiation resistance

Biological inert

In general, silicone rubber is biocompatible and meets the requirements of food applications.Because of its own stability, so without any additives and stabilizers.

Q4. Compared with silicone injection molding, what are the advantages of silicone 3D printing?

A: silicone 3D printing can directly convert digital models into physical objects without using any tools or molds, thus reducing production costs, especially for modeling or small batch production.

Another advantage of silicone 3D printing is that it saves production time.At the same time, it can improve the product rapidly during the product development.

Each 3D printed part can be customized to meet the needs of the oral or dental care industry and facilitate the production of anatomical models simulating human tissue.

ACEO ® can provide customized according to the requirements of the specific application of organic silicon

ACEO ® can provide customized according to the requirements of the specific application of organic silicon

What applications and industries will benefit from Q5.3D printed * silicone?

A: in industrial fields such as transportation or machinery and equipment, rapid modeling, small batch production of products and production of spare parts on demand are very important.

In the medical field, with organic silicon 3 d printing, can produce dental personalization applications such as clip or anatomical model, and ACEO ® products will also help to customize according to the different situation of specific patient treatment, so as to further promote medical education and preoperative planning.

Wacker has more than 70 years of silicone expertise and technology, so every process meets * industry standards.
