Sabic unveiled at Rapid + TCT 2017 (Pittsburgh, May 8-11) a new portfolio of high-performance filament grades for fused deposition modeling. The new products address growing global demand for greater material choices in the industrial filament market and lay the groundwork for Sabic’s strategy to help drive the growth of additive manufacturing from a prototyping technology to full-scale production. In addition to a long history of materials innovation, Sabic offers the expertise and resources to support testing, design and development of new additive manufacturing technologies.

“The launch of our first six new filaments, backed by Sabic’s world-class portfolio of high-performance engineering thermoplastics, will help us establish a pathway to introduce future breakthrough material solutions for additive manufacturing”, said Lori Louthan, director, Mass Transportation, Sabic. “We are applying our extensive materials and processing expertise to create new filaments with higher performance than current offerings with the goal of expanding their use into the development of production parts. Just as we’ve done for other plastics conversion processes in the past, Sabic aims to make an important contribution to the growth and success of our customers and the additive manufacturing industry through advanced materials and processes”.

Sabic’s new filaments, designed for use with Stratasys Fortus printers, are based on the company’s industry-leading Ultem PEI resin, Cycolac ABS resin and Lexan PC resin, and offer the same composition as the company’s injection moulding grades. Manufacturers can use the filaments to produce a range of high-performance, durable end-use parts.

These new materials solutions directly address the need for greater options in the industrial filament market and target a broad range of customer requirements. Both ABS and PC are well-established materials for additive manufacturing of prototypes and end use parts, while Sabic’s Ultem PEI filament is desirable for demanding applications that require high heat resistance, high strength, and low flame, smoke and toxicity (FST).

More specifically, these products include:

- Ultem AM9085F filament: this is a high-performance PEI product manufactured from Ultem 9085 resin; this product provides high heat resistance and mechanical strength, is UL94 V-0 compliant at 1.5 and 3.0 mm, and meets FAR 25.853 and OSU 65/65 requirements with low FST evolution. It is available in black and natural (unpigmented) colours;

- Cycolac AMMG94F filament: this is a general-purpose ABS product manufactured from Cycolac MG94 resin; it provides a balance of properties suitable for a wide variety of applications, and is UL94 HB compliant at 3.0 mm. It is available in black, white and natural (unpigmented) colours;

- Lexan AM1110F filament: this general-purpose PC product is manufactured from Lexan HF1110 resin; it provides thermal properties higher than those of general-purpose ABS filaments, is UL94 V-2 compliant at 3.0 mm and is available in white.

The nominal diameter of all Sabic’s filament products is 1.79 mm (±0.05 mm) and they are available in a 1510 cc spool size.

Sabic has also showed at Rapid + TCT, applications printed from its disruptive, developmental materials that have been designed for fused deposition modelling and can offer improved performance versus currently available products. These materials include:

- high impact strength polycarbonate filament for more robust performance during processing and secondary operations, as well as the ability to withstand high-impact end-use conditions;

- PC and Ultem healthcare filaments made with Sabic healthcare grade resins, enabling printed parts with excellent mechanical performance, sterilizability and biocompatibility;

- high-impact strength Ultem filament designed with the benefits of Ultem 9085 resin but with greater toughness;

- flame, smoke and toxicity compliant polycarbonate filament for use in demanding aerospace applications;

- Extem thermoplastic polyimide filament with heat resistance exceeding that of Ultem filament;

- breakaway support materials for Sabic’s Ultem, PC, and ABS filaments, providing additional choice in filament material supply.
