From the Sector

New products for photopolymer and laser sinter printing methods from BASF 3D Printing Solutions GmbH (B3DPS) are on show from November 13 to 16 at Stand F20 in Hall 3.1 at this year’s formnext fair in Frankfurt. The BASF subsidiary is also announcing several new partnerships for the development and distribution of groundbreaking 3D printing solutions and products.

B3DPS has entered into a strategic partnership with the US company Origin, San Francisco, California for the further development of photopolymer printing processes. “Within the framework of an open business model, we are combining BASF’s material know-how with Origin’s expertise in printer software programming and the manufacture of the corresponding hardware,” explained Volker Hammes, Managing Director BASF 3D Printing Solutions GmbH. The collaboration has already shown the first signs of success. Origin has developed a new printing method where BASF’s new Ultracur3D photopolymers can be processed particularly well. The technology offers an optimal combination of a good surface finish and high mechanical stability, while also allowing for high material throughput.

B3DPS is working together with Photocentric, a manufacturer of 3D printers and their corresponding software and materials, on the development of new photopolymers and large-format photopolymer printers for mass production of functional components. Based in Peterborough, UK and Phoenix, USA, Photocentric has developed and optimized the use of LCD screens as image generators for its own printing systems. The two partners plan to offer the industry 3D printing solutions that replace parts of traditional manufacturing processes such as injection molding for small series, as well as enabling the production of large components.

The objective of the cooperation with Xunshi Technology, a Chinese printer manufacturer headquartered in Shaoxing, and operates in USA under the name Sprintray, will be opening new fields of application in 3D printing for the Ultracur3D product range of B3DPS.

Ultracur3D specialties for photopolymer printing processes
B3DPS has grouped well-established and new photopolymers designed for the respective 3D printing processes under the brand name Ultracur3D. BASF has developed unique raw materials for its new products that enable special part properties.
“Our Ultracur3D portfolio enables us to offer customers various UV-curable materials for 3D printing that provide far better mechanical properties and higher long-term stability than most available materials,” explained András Marton, Senior Business Development Manager at B3DPS. He added: “These materials have been developed for functional components that are subject to high stress.”

Expansion of distribution network for filaments
Innofil3D, a subsidiary of B3DPS, is entering into a partnership with Jet-Mate Technology, based in Tjanjin, China, for the distribution of plastic filaments in China. In parallel, a distribution agreement has been concluded with M. Holland in Northbrook, USA for the distribution of filaments in USA. “Since the USA is the largest market for filaments, we intend to strengthen our activities there,” said Jeroen Wiggers, Business Director 3DP Solutions for Additive Extrusion at B3DPS, adding: “Asia is another important market for us. We will be developing further distribution channels there and putting our Ultrafuse filaments on the Asian market in 2019.”

BASF’s portfolio of filaments for 3D printing are comprised of two categories; the well-established Innofil3D filaments based on generic polymers for conventional applications and polymer-based Ultrafuse filaments for advanced formulations used in demanding technical applications. One of the broadest filament selections on the market, this portfolio covers customer requirements ranging from prototype to industrial-scale production.

SLS: new 3D printing material with fire protection classification
New flame-resistant Ultrasint Polyamide PA6 Black FR meets UL94 V2 fire protection standards and is a new material class for use in selective laser sintering (SLS) processes, distinguished by high stiffness and thermal stability. In cooperation with one of the global leaders of public transportation vehicles, B3DPS has developed new components that meet vehicle fire protection requirements. “Together with our partner, we are currently producing prototypes, spare parts, and small series components, and are working to further improve flame resistance to meet additional certification specifications,” explained Hammes.
BASF introduced Ultrasint Grey PA6 LM X085 at AMUG this spring and now is followed by another product on show at formnext. Ultrasint PA6 Black LM X085 is based on polyamide 6, and can be processed at 175-185 degrees Celsius therefore making it suitable for most current SLS machines.

B3DPS adds polypropylene to its 3D printing portfolio
Through the acquisition of Advanc3D Materials GmbH in July 2018, B3DPS has expanded its range with numerous materials for use on laser sinter machines, including polyamide Adsint PA12, Adsint PA11, Adsint PA11CF and Adsint TPU flex 90.
Ultrasint PP is a special highlight. This polypropylene-based product exhibits outstanding mechanical properties and is frequently used in standard industrial production as it offers a good balance between price and performance. Ultrasint PP is distinguished by excellent plasticity, low moisture uptake, and resistance to liquids and gases. Prototypes and small batches can now be produced from the same material as used for traditional serial production. Post treatments such as thermoforming, sealing, and dyeing can be performed after printing.

• Huntsman Textile effects redefines dyeing of polyester including microfiber and blends with UNIVADINE® E3-3D diffusion accelerant
• Eco-friendly diffusion accelerant provides reproducible, high-speed polyester dyeing

Singapore – Huntsman Textile Effects introduces UNIVADINE® E3-3D next-generation diffusion accelerant to help mills achieve high-performance dyeing of polyester, microfibers and blends in an environment-friendly way that complies with current and anticipated industry sustainability standards.

The demand for polyester and man-made fibers is booming as sports and athleisure apparel markets expand rapidly around the world. At the same time, big-name brands that set trends in the sector continue to increase focus on sustainability and performance. As such, this is putting pressure on mills since the current industry standard involves chemically active diffusion accelerants that contain unwanted chemicals and require additional leveling agents and anti-foaming products that may be hazardous to people and the environment.

Developed by Huntsman Textile Effects specifically to meet these challenges, UNIVADINE® E3-3D diffusion accelerant is low-odor, free of benzyl benzoate and other hazardous substances. Part of Huntsman’s range of innovative dyEvolution™ dyeing auxiliaries, it uses Huntsman’s Active Diffusion Technology to enable high-speed dyeing with best-in-class leveling, retarding and migration properties.

“UNIVADINE® E3-3D diffusion accelerant delivers across three key dimensions – diffusion, leveling and migration – for exceptional performance and environmental and economic sustainability. Its environmental credentials offer mills greater processing flexibility and an optimum price-performance ratio,” said Kerim Oner, Global Marketing Manager for Dyeing Auxiliaries at Huntsman Textile Effects. “We expect this latest offering to change the way that the industry dyes polyester and blends while meeting stringent environmental standards.”

UNIVADINE® E3-3D diffusion accelerant has a high affinity to polyester, causing the fiber to swell and increasing the diffusion of the disperse dye, even at lower temperatures. Multiple leveling mechanisms then slow down the exhaustion rate to ensure safe, defect-free dyeing. Finally, as the dye bath heats up, the product’s strong support for disperse dye migration ensures the dye molecules are evenly absorbed.

As a result of this cutting-edge diffusion technology, UNIVADINE® E3-3D diffusion accelerant can be used to successfully dye polyester fibers in tightly wound or high-density yarn/beam dyeing and is suitable for jet applications without the need for anti-foaming products. Reducing exposure to high heat, its Active Diffusion Technology minimizes the potential to damage the elastane in polyester-elastane blends and provides for on-tone dyeing of microfibers. The superior migration support of UNIVADINE® E3-3D diffusion accelerant also increases reproducibility, allowing mills to dispense with additional leveling agents. Polyester, microfibers and blends treated with UNIVADINE® E3-3D diffusion accelerant comply with the requirements of bluesign®, in addition to being suitable for Standard 100 by OEKO-TEX® and an approved input dyeing auxiliary chemical for GOTS (Global Organic Textile Standard) certified textile products*.

Attendees of the Association for Professionals in Infection Control and Epidemiology (APIC) expo confirmed Thursday the value of effective guidelines for properly handling clean linen, substantiating Hygienically Clean Healthcare certified operators’ efforts to help them ensure linen remains safe and clean when it reaches patients.

Visitors to the Hygienically Clean exhibit at APIC’s Annual Conference were supported in this respect by receiving Handling Clean Linen in a Healthcare Environment, a guide produced by these certified linen, uniform and facility services operators. APIC attendees shared anecdotes of mishandling clean linen in their workplaces including:

• Employees holding and carrying stacks of bed linen and towels touching their chests
• Commingling clean and soiled linen
• Storing linen in closets in guest rooms instead of a secure linen room

Certified operators’ certification fees provided funding for creating and distributing the guide (and other resources for healthcare facilities), manifesting the Hygienically Clean program’s philosophy of addressing healthcare providers’ operational needs outside the scope of outsourced laundries’ traditional functions.

Angela Freeman, Hygienically Clean program manager, explained the importance of such laundries partnering with healthcare providers to create and implement plans to ensure clean textiles are delivered to patients. “When healthcare textiles (HCTs) reach a facility’s doors, an outsourced laundry’s role in maintaining their hygiene depends greatly on how the service agreement addresses linen distribution. Hygienically Clean’s resources for healthcare providers reflect the willingness of our certified operators to partner with their customers.”

A video version of the clean linen guide is in the works. TRSA, the global association for the linen and uniform services industry and Hygienically Clean administrator, continues to build the industry’s appreciation for partnering with healthcare customers.

In May, TRSA introduced Producing Hygienically Clean Textiles, an e-learning class to help laundry employees understand their roles in the processes, procedures and policies necessary to produce clean linens and uniforms. TRSA’s annual Healthcare Conference has guided industry managers in progressive linen distribution techniques to aid their training of their customers in these.
