Dental 3D printing started as a hobby for Dr. Andrew Ip — and turned into a global movement he now helps lead. On this episode of The Technology Evangelist Podcast, host Dr. John Flucke sits down with the Sydney-based general dentist, multi-brand KOL, and internationally recognized 3D printing educator to talk about how this technology has evolved from a novelty into an essential clinical tool. From solid models to surgical guides to cosmetic mock-ups, Dr. Ip offers a rare combination of hands-on experience with over 42 different printers and a genuine educator’s commitment to making dental 3D printing accessible to every practice, everywhere. This episode is brought to you by Medidenta Digital Solutions, proud sponsor of this podcast and distributor of the Rodin line of 3D printing resins from Pac-Dent.
Key Insights on Dental 3D Printing and Digital Dentistry Innovation:
- From Hobby Printer to Global Educator: Dr. Ip’s entry into dental 3D printing had nothing to do with dentistry. He was using a consumer printer for toys, gadgets, and household items when a dental rep asked him to print a few study models — and offered to pay him for the trouble. That small transaction sparked a curiosity that has now grown into a practice built significantly around 3D printing, an international lecture schedule spanning Australia, Asia, Europe, and the United States, and a personal tally of 42 different 3D printers tested and reviewed. He credits that accidental beginning with keeping his perspective grounded: he approaches the technology as a clinician and a tinkerer, not a brand ambassador.
- The Real Bottleneck in Digital Dentistry Is Design, Not Printing: Dr. Ip is direct about where most clinicians struggle: the physical workflow of printing, washing, and curing has become straightforward and teachable. The historical barrier has been design software, which traditionally required mastery of high-ceiling programs with steep learning curves. The good news, he explains, is that artificial intelligence is rapidly changing that — with programs now capable of auto-detecting margins, generating crown anatomy, merging cone beam data with intraoral scans, and even suggesting implant positions. For most clinicians, the design step is no longer the obstacle it once was.
- Start Simple — Solid Models First: Both Dr. Ip and Dr. Flucke agree on the right entry point for practices new to dental 3D printing: start with solid models. Most major intraoral scanner brands include a free model builder in their software, which means there is no additional design cost, no complex orientation decisions, and no drain hole management. Hollow models, which save resin and make sense for high-volume labs, add layers of technical complexity that are simply not worth the savings for an office printing a handful of models per case. Once solid models feel routine, Dr. Ip recommends progressing to occlusal guards, clear aligner models, and then surgical guides.
- Surgical Guides Are Becoming the Standard of Care: Dr. Ip makes a compelling case that implant surgery without a guide is increasingly difficult to justify — not just clinically, but from a risk management standpoint. He notes that in Australia, cone beam imaging before implant placement has effectively become an industry expectation, and predicts surgical guides will follow the same trajectory. Beyond precision, he points out a less-discussed benefit: the act of designing the guide forces the clinician to study the patient’s anatomy in far greater detail than they otherwise would, so that by the time the patient is in the chair, there are no surprises. He recommends including visibility windows in guide designs so seating can be verified visually before drilling begins.
- Delegating the Design Work Is Not Cheating: A point both hosts emphasize is that clinicians do not have to design everything themselves. Just as no one expects the doctor to pour their own gypsum models or mill their own zirconia crowns, there is no reason they cannot delegate 3D design to a trained assistant, an in-office technician, or an external lab — then simply review, approve, and print. Dr. Ip draws a direct comparison to the standard lab model workflow most practices already use, arguing that digital dentistry should feel like a natural extension of existing delegation habits rather than a new burden on the doctor’s schedule.
- True Model Prime and the Value of Multi-Use Resins: Dr. Ip shares his initial impressions of Pac-Dent’s True Model Prime resin, noting its CLASS I biocompatibility certification as a meaningful differentiator — allowing the same material to be used for models, custom trays, and temporary restorations. For offices or clinics with limited printer capacity or storage space, a resin that can serve multiple clinical applications without requiring dedicated equipment for each use type is a significant practical advantage. He sees multi-use materials as an important direction for the market and a smart play by manufacturers who recognize real-world inventory constraints.
- Characterization and the Palette 2.0 Staining System: When it comes to finishing and characterizing 3D printed restorations, Dr. Ip uses Pac-Dent’s Palette 2.0 staining and glaze system regularly, citing its consistency, handling properties, and ease of use compared to thinner staining systems that can be difficult to control. He specifically highlights the Glaze and Free product — a glaze that eliminates the oxygen inhibition layer without requiring a specialized curing environment — as a genuinely useful innovation that he reaches for almost daily. Dr. Flucke echoes that assessment and showed the full kit on camera for viewers to reference.
- Cosmetic Mock-Ups and Patient Conversion: Dr. Ip’s workflow for cosmetic cases involving snap-on smiles or diagnostic wax-up print-outs includes printing two fully processed sets — one for in-office photography and patient review, and one for the patient to take home. Sending the patient home with a physical mock-up allows everyone involved in the decision — spouses, family members, close friends — to weigh in before the clinical conversation continues. He has found this dramatically reduces last-minute hesitation and sets clearer expectations before any irreversible treatment begins.
- Free Resources and an Open-Door Philosophy: Dr. Ip maintains a YouTube channel (searchable as “i3D dental”) and a review website where he publishes fully independent, unsponsored 3D printer reviews — something he does purely to help clinicians make informed purchasing decisions. His workshop walkthroughs covering software workflows for a wide range of programs are freely available on the channel and annotated for easy reference. His stated goal is to democratize dental 3D printing — to ensure that a two-chair practice in a small community has the same access to this technology as a high-end cosmetic office in a major metro area.
Dr. Andrew Ip represents exactly the kind of practitioner who makes dental 3D printing better for everyone — someone who pushes the technology to its limits, shares what he learns without holding anything back, and shows up in Singapore one week and Chicago the next to make sure the knowledge spreads. Whether you have never touched a 3D printer or already own several, his perspective is worth following.
