Stephan Kreimer, a Master Dental Technician and the director of Kreimer Dentallabor GmbH & Co. KG, runs a state-of-the-art dental laboratory that specializes in digital workflows. Over 80% of their cases arrive digitally, processed by a team of 12 skilled dental technicians in a workspace optimized for digital efficiency. Kreimer emphasizes the importance of investing in high-quality hardware and materials. He believes it’s a smart move that enhances efficiency and redefines their workflow. He shares, “The impact has been nothing short of revolutionary." Kreimer's lab is highly productive, producing approximately 300 dental models monthly, with 60% being precise restorative models. They also fabricate biocompatible appliances such as occlusal splints, surgical guides, provisionals, and custom impression trays. To achieve this, 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 creation. The intuitive workflows and ease of use of the Formlabs ecosystem have led to significant time savings and cost reductions. At a time when skilled labor is scarce and costly, adopting efficient solutions is transformative. Kreimer is constantly evaluating new technologies and materials in the dental 3D printing space. After rigorous testing, he adopted Fast Model Resin and Precision Model Resin, finding they not only cut down on time and costs but also eliminated unnecessary patient appointments for collaborating dentists. Kreimer Dentallabor’s facility was designed with digital dentistry in mind, featuring a CAD/CAM area, a CNC machining room, and an expansive 3D printing space equipped with eight printers. Recently, they added the Form 4BL, a large-format 3D printer that offers a build platform 2.7 times larger than the Form 4B, significantly boosting throughput. Stephan explains, “With the Form 4BL’s build platform, which is three times larger, we can now produce three times more models with just one user intervention.” The Form Wash L complements the Form 4BL by enabling the washing of an entire build platform at once, streamlining post-processing and freeing up technicians for higher-value tasks. Stephan adds, “We are currently using the Form 4BL for all our model production and the Form 4Bs for biocompatible applications. This assignment of printers is a big improvement over our previous workflows.” When comparing their efficiency levels from a decade ago to today’s digital workflows, Stephan notes, “Our employees are two or three times more efficient with this technology.” Setting up the Form 4BL was straightforward, taking only 15 minutes. Stephan highlights, “Digital technology helps onboard new employees faster, allowing them to achieve a high level of quality much quicker than before.” The reliability of Formlabs printers minimizes remakes, ensuring appliances fit perfectly the first time. Fine details and smooth finishes reduce post-processing time. For instance, occlusal splints printed with Dental LT Comfort Resin require minimal polishing. All Formlabs printers share the same intuitive workflows, allowing team members to seamlessly transition between different models. Kreimer extensively evaluates resins to select the optimal ones for each application. He uses specific Formlabs resins after thorough testing, including Dental LT Comfort Resin for occlusal splints, Surgical Guide Resin for guides, and BEGO™ VarseoSmile® TriniQ® Resin for restorations. These materials provide highly precise and accurate appliances that fit perfectly. The release of Form 4B introduced two new materials: Precision Model Resin and Fast Model Resin. Stephan rigorously tested these, finding Precision Model Resin ideal for restorative models due to its exceptional surface accuracy and matte aesthetics. Internal testing at Formlabs showed that parts printed with Precision Model Resin have 99% of the surface within 100 μm of the CAD model and 95% within 50 μm at 50 μm layer heights. Kreimer appreciates the ability to use both Precision and Fast Model Resins. While Precision Model Resin excels in precise applications, Fast Model Resin offers rapid printing for less critical cases. He concludes, “You don’t need a lot of materials as long as you have the two that meet your specific needs.” By optimizing resin selection for each application, Kreimer Dentallabor achieves maximum efficiency. Stephan hopes for full adoption of intraoral scanning to streamline workflows further. For more insights, join our webinar or contact a dental expert today.
