The In-House 3D Printed Aligner Workflow: From Scan to Same-Day Smile

Dental practices worldwide are discovering how in-house 3D printed aligners can completely reshape their orthodontic workflows, turning what once took weeks into same-day treatments that delight both practitioners and patients. A 3D Printed Aligner Workflow enables dental practitioners to produce custom orthodontic appliances directly in their clinics, dramatically reducing treatment times from weeks to hours while maintaining exceptional quality and precision. This comprehensive In-House 3D Printed Aligner approach leverages LuxCreo’s integrated ecosystem of hardware, software, and materials to deliver same-day orthodontic solutions.

The Evolution of Clear Aligner Therapy

Clear aligner therapy has become the preferred orthodontic treatment for millions of patients worldwide, offering aesthetic appeal and treatment convenience. Traditional workflows rely on outsourced manufacturing, creating lengthy turnaround times that can delay treatment starts and reduce patient satisfaction. The emergence of In-House 3D Printed Aligner technology addresses these challenges by bringing production capabilities directly into dental practices.

Benefits of In-House 3D Printing vs. Outsourced Workflows

The transition from outsourced thermoforming to direct 3D printing delivers transformative advantages. Traditional thermoformed aligner production requires at least 2-4 weeks for delivery, while the 3D Printed Aligner Workflow reduces this to just 2-3 hours from scan to delivery. This dramatic reduction in turnaround time enables same-day treatment starts, improving patient conversion rates and practice efficiency.

LuxCreo’s direct printing technology achieves 80% higher clarity compared to competitors while reducing polishing time by 75%. The system delivers 3x revenue growth with the same workforce through increased labor productivity, with only 1.5 minutes of active labor required per aligner compared to 5.5 minutes for traditional workflows.

Overview of LuxCreo’s Integrated Ecosystem

LuxCreo’s comprehensive solution encompasses every aspect of the 3D Printed Aligner Workflow, from initial scan processing to final delivery. The ecosystem includes the FDA-cleared aligner material DCA, LuxDesign software for automated aligner shell generation, LuxFlow for print preparation, and specialized post-processing equipment, including iLuxWash Dental and iLuxCure Pro.

Scan-to-Delivery 3-Hour Experience

LuxCreo’s clear aligner production workflow: the clinician performs an intraoral scan to capture the patient’s oral anatomy and dentition, imports the data into treatment-planning software to auto-generate the treatment an AI-driven plan, then loads the plan into LuxDesign for aligner shell design. Without any file-format conversions, the design is sent directly to LuxFlow for slicing and print preparation, then to the iLux Pro Dental for printing. After a brief iLuxWash cleaning and iLuxCure curing process, the patient receives their custom aligner— all within just three hours.

Capturing the Patient’s Oral Anatomy

Intraoral Scanning Technologies: Speed and Accuracy

The 3D Printed Aligner Workflow begins with high-resolution intraoral scanning to capture precise digital impressions of the patient’s dentition. Modern scanning technologies provide accuracy within 20-50 microns, enabling the creation of detailed digital models that serve as the foundation for aligner design.

Treatment Planning and Digital Setup

Generating Tooth Movement Sequences

Orthodontic tooth movement is performed in third-party treatment planning software such as 3Shape, Ulab or TiTan. LuxCreo’s LuxDesign software then seamlessly integrates with these platforms to automatically generate aligner shell models specifically optimized for direct 3D printing.

Automating Aligner Shell Creation with One-Click AI

Powered by AI, LuxDesign automatically repairs models, generates block-outs, and creates optimized aligner shells for direct 3D printing—all in just one click.

Special Features of LuxDesign:

• Automatic Gap Filling Option
• Trimline Adjustments for Perfect Fit
• Customized Thickness for Optimized Force Control
• Auxilliary Attachments for Customized Device

Comparing Multi-Thickness vs. Uniform-Thickness Strategies

LuxCreo’s 4D Aligner technology enables multi-thickness design with AI-generated thickness and gap variations to enhance control and achieve targeted force application. This approach provides superior biomechanical control compared to uniform-thickness aligners, enabling more predictable tooth movement with fewer attachments required.

Instead of replacing clinical judgment, this workflow puts doctors in full control of treatment design while eliminating time-consuming manual steps. From trim-line creation to shell preparation, LuxDesign streamlines the entire process so clinicians can focus on what matters most: delivering better outcomes for patients.

Preparing for Print: LuxFlow Software

LuxFlow software streamlines every step of the 3D printed aligner workflow by automating model preparation, support generation, and slicing to meet demanding same-day throughput requirements. Imported STL files are automatically inspected and repaired to eliminate mesh irregularities, while intelligent orientation algorithms position each aligner for maximum print accuracy and minimal material usage.

Advanced support-generation routines create optimized structures that reduce post-processing time, and high-speed slicing and batching capabilities process multiple models simultaneously with resin-specific print parameters. The result is a fully integrated, efficient production pipeline that delivers consistent, high-quality aligners on the same day they are scanned.

Direct 3D Printing of Clear Aligners

Choosing the Right Printer: iLux Pro Dental

The iLux Pro Dental represents LuxCreo’s desktop solution with a build volume of 192 x 108 x 200mm and 50μm pixel pitch, ideal for chairside applications.

Post-Processing and Digital Polishing

Unloading, Washing, and Drying Printed Aligners

Post-processing begins immediately after printing completion, with careful removal of aligners from the build platform. Using appropriate tools, followed by thorough cleaning to remove uncured resin residues.

iLuxWash Dental – Automated Ultrasonic Agitation

The iLuxWash Dental system enhances ultrasonic cleaning through magnetic-driven impeller stirring function, rapidly agitating the cleaning solution while featuring heating functionality. This automated system prevents distortion issues from over-soaking while ensuring complete resin removal from printed parts.

iLuxCure Pro – Consistent, 360° UV Curing

iLuxCure Pro provides upward and downward high-intensity lighting with heating function and 360° curing coverage. The system operates at 405-385nm wavelength with 95% uniformity, ensuring complete polymerization throughout the aligner structure. Heat curing at 60°C (140°F) optimizes mechanical properties and dimensional stability.
