Formlabs, a leading 3D printing company, announced the launch of two new proprietary SLA Resins – Rigid 10K Resin and a reformulation of Draft Resin, to expand design capabilities for users and enhance what’s possible with 3D printing.

Speaking at the launch, Max Lobovsky, CEO and co-founder of Formlabs commented, “One of the most powerful advantages of Stereolithography (SLA) 3D printing is the wide range of printing materials. Our customers don’t just need parts with the right geometry, they also need the right material properties. With our expansive library of SLA resins, our users can make anything from surgical tools, to retainers, to jigs and fixtures and everything in between.”

Formlabs reformulated its Draft Resin to allow users to print up to four times faster than the existing resin options without compromising on the quality and performance. The new SLA resin formulation offers improved surface finish, post processing requirements, and a new grey colour.

Features of New Draft Resin

  • Prints up to four times faster than standard materials
  • Minimal support removal, wash, and cure times
  • Ideal for: 
  • Initial prototyping
  • Rapid iterations
  • Live 3D printing demos
  • High throughput

The new Draft Resin can be used for a varied range of applications including manufacturing, engineering, dental and orthodontic fields. It can effortlessly 3D print aligners and retainer models in under 20 minutes. It can now allow chair-side or same-day delivery for orthodontic practices.

For dental labs, Draft Resin enables improved throughput and efficiency, producing over 95 models per day on a Form 3BL. Compared to Formlabs Grey Resin, which can print eight models in 9 hours and 48 minutes, Draft Resin accomplishes this in just 1 hour and 30 minutes. From set-up to post-processing, Draft Resin builds on Formlabs’ easy-to-use, accurate, and reliable 3D printers, while bringing print speeds to new levels.

Rigid 10K Resin is the stiffest material in Formlabs’ entire portfolio, meeting engineering and manufacturing customers’ need for a stiffer, more heat and chemically resistant material. Together, Draft Resin and Rigid 10K Resin complement the natural progression of product development, supporting customers from quick initial designs through high performance parts.

Features of New Rigid 10K Resin

  • Stiffness that simulates glass or fiber-filled thermoplastics
  • Resistance to heat, chemicals, and intense pressures resulting in a prime choice for precise industrial parts that need to withstand significant load without bending
  • Smooth matte surface finish
  • Ideal for: 
    • Short run injection mold masters and inserts
    • Aerodynamic test models
    • Heat resistant and fluid exposed components, jigs, and fixtures

Rigid 10K has enabled users like Novus Applications, an engineering and consulting company focused on the consumer packaging industry, to create 3D printed moulds and inserts, making their injection moulding workflow more efficient. The company utilizes Rigid 10K SLA Resin to 3D print short-run injection moulds and cores while reducing both costs and manufacturing time. Rigid 10K Resin was extremely valuable for the company as its ability to withstand high temperatures and immense pressure was unmatched by other materials. 

Mark Bartlett, President and Founder of Novus Applications said, “It was performing at a level that we hadn’t seen historically capable in the traditional Rigid [4000] material. I can print complex forms accurately, way faster than I’m going to machine them.” The advanced strength ensures a mould made from Rigid 10K SLA Resin can withstand the clamping and injection pressures without breaking, while the high stiffness enables the mould to maintain its shape under these pressures and produce accurate parts.
