B9Creations Launches New Robust Resin Line With 3D Mold Printing Potential


The voting lists for the 2021 3D Printing Industry Awards are now open. Who do you think should receive the highest honors this year? Give your opinion now.

3D printer maker B9Creations has launched a new line of resins that it says can be used to create quality plastic molds for injection molding.

This “Heavy Duty” range includes ABS and Polycarbonate (PC) material that exhibits a high thermal deflection temperature (HDT), making it ideal for producing smooth and impact resistant molds. Along with its ABS / PC thermoplastic, the company also launched an equally resilient engineering grade ABS, which when used with its B9 Core Series 3D printers would produce strong, rigid and very stable parts.

A growing portfolio of materials

As the self-proclaimed “innovation engine” of 3D printing, B9Creations provides systems, materials and services to manufacturers in the jewelry, prototyping, research and medical industries. Over the past ten years, the company has built up a large portfolio of machines, including a B9 scanner, as well as the B9 Core Med 550 and XL 3D printers, and its B9 Core Series 530, 550 and XL speed oriented DLP systems.

When it launched in 2017, the company’s flagship machine was marketed as having a print speed four times faster than average and a throughput over a day of 8 to 10 hours of “hundreds of models.” Since then, B9Creations’ printers have continued to find new industrial and medical applications, such as Ding Tool using them to 3D print auto body tools two years later.

More recently, US social services group Black Hills Works partnered with B9Creations to additively manufacture personalized assistive devices for more than 600 people with disabilities. Over the course of the project, the organization would have LCD 3D printed kitchen utensils, portable devices, wheelchair handles, waterproof call lights, specialized work tools and more.

To continue unlocking applications for its technologies, the company also invested in expanding its materials offering, launching its B9Captivate toolkit, before opening a $ 500,000 R&D lab. This commitment now appears to be paying off, as after the company’s release of FastWax Castable resin last year, it is now launching two more materials, with the aim of making short-term production more achievable.

Presentation of the Robust range

Designed specifically for use with its B9 Core Series machines, although compatible with its 5 Series XL systems with some rejigging, B9Creations’ new materials feature the same impact resistance and produce parts with a similar finish.

However, while Robust ABS effectively emulates the strength and stability of ABS plastics when used in a manufacturing environment, ABS / PC exhibits a higher flexural modulus of 1.6 GPa. As a result, the latter can be used to 3D print alternatives to traditional metal or injection molded molds, potentially allowing manufacturers to cut costs for such parts from $ 5,000 to $ 10,000, down to just 1 at $ 10.

While the design and production of conventional molds can take up to six weeks, 3D printed substitutes can also be created in under an hour. By purchasing molds in this way, adopters not only strengthen their supply chains, but tailor their workflow from prototyping to production in the short run, while the resulting parts could enable them to process materials better suited to their needs. needs. .

Already, Robust ABS / PC has been adopted by an anonymous customer, whom B9Creations considers “one of the largest manufacturers in the United States”. went from producing five parts with other technologies to 3D printing more than 100 parts in the same time frame.

“I can get high precision parts in an hour,” said a spokesperson for the manufacturer. “This has not only enabled our R&D, but it has also enabled our manufacturing to expand and open up a wide range of low-volume custom activities that we have had to refuse in the past due to cost and minimum quantity requirements. control. “

Industrialize DLP production

B9Creations continues to market its larger B9 Core Series 3D printers as “volume production” machines, but it’s not the only DLP system maker looking to industrialize the technology. Austrian optical device developer In-Vision, for example, earlier this year launched its first 4K UV light projector for use with resin-based DLP 3D printers, designed to meet industrial throughput requirements.

In December 2020, Stratasys also strengthened its commitment to the high-speed DLP market with its acquisition of Origin for $ 100 million. The Origin One 3D printer is designed to enable mass production of end-use parts, and after the company’s takeover last year, Stratasys CEO Yoav Zeif praised the machine’s speed for him. have helped capture a “range of in-demand production applications.” “

Similarly, the manufacturer of high-speed extrusion 3D printers (HSE) Essentium signed a letter of intent to acquire Collider in July 2021. The latter is developing a “Programmable tooling” process, which combines additive manufacturing with molding. by injection in a way that could enable it to meet the needs of players in the automotive, aerospace and medical sectors.
