Stephan Kreimer, a Master Dental Technician and the director of Kreimer Dentallabor GmbH & Co. KG, manages a full-service dental lab that specializes in digital workflows. Over 80% of their cases are received digitally and processed by a team of 12 skilled dental technicians in a workspace designed for digital efficiency.
"Investing in high-quality hardware and materials has been a game-changer for our lab," Stephan explains. "This investment has greatly enhanced our efficiency and transformed our workflow. The impact has been nothing short of revolutionary."
Kreimer's lab is highly productive, with the team 3D printing approximately 300 dental models each month. About 60% of these models are precise restorative models, along with biocompatible appliances such as occlusal splints, surgical guides, provisionals, and custom impression trays. To support this output, Kreimer Dentallabor has assembled a diverse fleet of 3D printers, including the fast and accurate Form 4B for biocompatible production and the large-format Form 4BL for high-throughput model production.
"The intuitive workflows and ease of use of the Formlabs ecosystem have significantly improved our efficiency," Stephan adds. "This has led to time savings and reduced costs for the lab. In an era where skilled labor is scarce and costly, investing in efficient solutions is essential."
To maintain their high standards of care, improve efficiency, and cut costs, Kreimer is constantly evaluating new technologies and materials in the dental 3D printing field. After extensive testing, he adopted Fast Model Resin and Precision Model Resin, finding that producing restorations on restorative models printed with Form 4BL and Precision Model Resin not only saved time and costs but also eliminated the need for additional patient visits for collaborating dentists.
Kreimer Dentallabor’s space was designed with digital dentistry workflows in mind, featuring a CAD/CAM area for design, a dedicated room for CNC machining, and a dedicated room housing eight 3D printers. One of the latest additions to their fleet is the Form 4BL, a large-format 3D printer that offers a 2.7x larger build platform than the Form 4B. This expansion allows technicians to print three times as many models per batch, reducing the frequency of user interventions and freeing up staff for higher-value tasks.
Stephan emphasizes, "With the Form 4BL's build platform, we can now produce three times more models with just one user intervention. This significantly improves our throughput and efficiency."
Adding Form 4BL to the lab's printer lineup has streamlined their workflow. The Form Wash L, a large-format washing solution, allows technicians to wash an entire Form 4BL build platform at once, further optimizing the post-processing workflow.
"Our employees are two to three times more efficient with this technology," Stephan notes. "Digital technology helps us onboard new employees faster, allowing them to achieve a high level of quality much quicker than before."
Reliable equipment ensures fewer remakes, reducing the need for adjustments and improving the overall fit of appliances. For example, occlusal splints printed with Dental LT Comfort Resin require minimal polishing, saving time and effort.
Formlabs' printers share the same intuitive workflows, enabling seamless transitions between machines like Form 3B+, Form 4B, and Form 4BL. This flexibility allows labs to scale production without increasing staff demands or overhead costs. Stephan concludes, "By investing in labor-saving technology, we allow our team to complete more work, which increases revenue. The real profit comes from the case, not just the models. Less time spent on post-processing and printing gives us more time to focus on producing high-quality dental appliances."
Formlabs' dental resins offer versatility, with Kreimer extensively testing materials to find the optimal resin for each application. They use Dental LT Comfort Resin for occlusal splints, Surgical Guide Resin for guides, and BEGO™ VarseoSmile® TriniQ® Resin for restorations, ensuring precise and accurate appliances that fit perfectly every time.
The introduction of Form 4B brought two new dental materials: Precision Model Resin and Fast Model Resin. Stephan rigorously tested these resins, printing models to assess accuracy and precision. He thoroughly evaluated Precision Model Resin, conducting detailed tests to confirm its suitability for restorative models.
"With Precision Model Resin, the surface accuracy is among the best I’ve measured," Stephan remarks. "The entire surface is nearly identical to the original dataset, and the print quality is consistently excellent."
Internal testing at Formlabs shows that parts printed with Precision Model Resin have 99% of the surface within 100 μm of the CAD model and 95% within 50 μm when printed at 50 μm layer heights.
Kreimer also found Fast Model Resin ideal for less demanding applications like splint models, aligner models, or provisionals, where speed is more critical than absolute precision. This dual-material approach optimizes efficiency across different applications.
The majority of dentists Kreimer works with follow a digital workflow, appreciating the lab’s expertise and the time savings it provides. "We can start and finish even large cases on the Precision Model Resin printed model, eliminating the need for corrections," Stephan states. "This efficiency saves valuable time for both dentists and patients."
Kreimer's commitment to digital dentistry and Formlabs' solutions has led to a streamlined, efficient operation. He hopes for full adoption of intraoral scanning, confident that this will deliver the best outcomes for clinicians and their patients.
