Select the Best Dental 3D Printer for Your Practice

3D printing is used in many industries, allowing designers the ability to quickly turn concepts into three-dimensional models or prototypes. 3D printing technology often saves money over other manufacturing techniques because very little raw material is wasted in the process. With the advent of high-quality 3D printers that produce final products to exacting specifications, it’s no surprise that 3D printing is transforming the dental industry.

A few years ago, 3D printers suitable for dental applications were affordable only to the largest dental laboratories. Now they are accessible to smaller dental labs and practices of all sizes.

The most common orthodontic and dental 3D printers work by selectively exposing liquid resin to a light source, either by stereolithography (SLA) using a laser beam to cure dental resins or by Digital Light Processing (DLP) which involves using a projector to solidify very thin layers of resin that stack up to create a solid object.

The way they work is similar. Differences in 3D print quality, workflow, materials, costs, and other factors generally depend on the characteristics of the specific machine chosen rather than the type of curing technology employed.

Dental 3D Printer Digital Workflow

Dental 3D printer workflow used in everyday dental processes may be broken down into four basic phases:

Convenience

By replacing traditional impression-taking methods with digital scanning technology, dental 3D printers offer a more convenient and comfortable experience for both patients and dental professionals. Patients no longer need to endure uncomfortable trays filled with impression material, while dentists can capture precise digital impressions quickly and efficiently.

Time-Saving

The ability to produce dental models and appliances directly in the dental office eliminates the need to wait for external laboratories to fabricate them. This significantly reduces turnaround times, allowing dentists to provide faster treatment to their patients. Additionally, the on-demand nature of 3D printing enables dental professionals to respond promptly to patient needs and emergencies without delays.

Advance Preview

One of the most significant advantages of dental 3D printers is the ability to preview and modify the design of the final restoration before fabrication. Dentists can use digital software to visualize the proposed restoration in detail, making adjustments as needed to achieve the desired aesthetic and functional outcomes. This advanced preview capability enhances communication between dentists and patients, ensuring that expectations are met and treatment goals are achieved.

Accuracy and Precision

Dental 3D printing technology offers unparalleled levels of accuracy and precision in the fabrication of dental appliances and prostheses, including dental implants, dentures, surgical guides, custom trays, and more. The automated nature of the printing process ensures consistent results, minimizing the risk of errors or inaccuracies associated with manual fabrication techniques. As a result, dental restorations produced with 3D printers exhibit precise dimensions and fit seamlessly within the patient’s oral cavity.

Fewer Defects

Additive manufacturing techniques employed by dental 3D printers, such as digital light processing technology, result in dental restorations with fewer defects and imperfections compared to traditional fabrication methods. 3D dental printing works layer by layer, producing complex geometries and intricate designs with exceptional detail and structural integrity. This reduces the likelihood of defects such as voids or inconsistencies within the biocompatible materials, resulting in more durable and long-lasting dental restorations.

Benefits of a Dental 3D Printer

Dentists are choosing to invest in dental 3D printers because of the number of benefits they offer when compared to the traditional methods of fabricating dental appliances.

How To Choose the Best Dental 3D Printer

Balancing the advantages and disadvantages of a number of factors, including cost and accuracy, will help you to determine which printer is the best choice for your specific application.

Use

Determine how you plan to incorporate and use 3D printing in your practice. Different printers excel at different procedures. If you are interested in using the printer to produce study models, mouthguards, and surgical stents, investing in a high-quality printer that makes precision orthodontic appliances or denture parts would not be a good use of your resources.

Precision and Accuracy

Generating accurately-fitting appliances is of paramount importance for any dental practice when time and money have been poured into the best dental 3D printer. For 3D technology to be beneficial, the prosthetics made using digital printing must fit more precisely and be of better quality than those produced by the traditional methods. Otherwise, why would anyone do them?

Not all dental 3D printers are created equally. Many come with a lot of bells and whistles that don’t necessarily translate into a better-quality final product. What makes a printer the best dental 3D printer is all of its components must be calibrated to work like a well-oiled machine in order for a restoration with superior fit and appearance to be produced. Some important components of 3D printing include:

• The type of technology chosen
• The quality of the printer
• The chemistry of the resins and materials
• The software that interprets the scanned and designed images
• How restorations are handled and processed manually after printing

There is really no way to look at the specifications related to printing accuracy from a variety of manufacturers and determine which printer is the most accurate and the best dental 3D printer for your practice. The proof is in the final appliance. The quality of the end product will determine whether the printer meets your needs. Ask printer manufacturers to demonstrate their printer in action. Judge for yourself if the product produced exceeds your expectations.

Ease of Use/Easy To Maintain

Who has time for another piece of software that is not intuitive or far too complex to use? A dental office is a busy place and the equipment must be user-friendly for maximum productivity. In addition, you or your staff will need to maintain the printer and its related components on a daily basis. Try to get a sense of the learning curve involved prior to purchase.

Reliability

The most important factors in dental 3D printing are reliability and repeatability. Dental 3D printers must be able to consistently deliver the same high-quality prints, over and over, without wavering, especially in a dental environment where quality control is expected.

Cost

Basic entry-level desktop SLA or DLP 3D printers, suitable for printing models and such, start at around $1,000. Higher-quality laboratory-grade dental additive printers can cost up to $10,000 or much more.

When comparing dental 3D printers, consider not only their upfront costs but also the cost to operate and service the equipment on an annual basis. The price of dental 3D printers is based on a number of factors that include:

Print quality – printers offering greater detailed resolution are more expensive.

Build volume – more expensive dental 3D printers usually print and cure a greater volume of resin in one pass, allowing for faster production without sacrificing accuracy and detail.

Dental 3D software –The intraoral scanning software and design software are important components of digital dentistry. Higher-quality scans, in general, yield a better final product.

Reliability and repeatability – These are two of the main reasons why some dental 3D printers command a much higher price point than others – they reliably produce precision results over and again. In other words, you can count on them to deliver the same great quality appliance or prostheses every time. Reliable printers will save you money in the long run.
