5 Days Around Dental 3D Printing: What post-processing solutions are available for 3D Printed dental devices?

5 Jours Autour de l’impression 3D dentaire : Quelles solutions de post-traitement pour les dispositifs dentaires imprimés en 3D ?

In high-volume FDM production, automated post-printing is a necessity for meeting demand at scale.

We’ve seen firsthand how additive manufacturing has evolved, especially for Fused Deposition Modeling (FDM). And as print volumes increase, one challenge continues to stand in the way of efficiency: manual post-processing.

For facilities running dozens or hundreds of FDM builds per week, traditional methods of support removal are time-consuming, inconsistent, and difficult to scale. Between chemical baths, overnight drying cycles, and intensive manual labor, post-printing can quickly become the biggest bottleneck in your additive workflow.

That’s where automation changes the game.

At PostProcess Technologies, we work with manufacturers every day who are scaling up FDM production with automation, and we’re here to help enhance your workflow.

In this blog, we’ll explore how to streamline FDM post-processing with intelligent, automated solutions that eliminate manual labor, reduce operator intervention, and enable high volume throughput.

Why Traditional Post-Processing Can’t Keep Up

FDM has long been the go-to technology for prototyping and high volume end-use parts. As manufacturers shift toward larger, production-scale volumes, the same tools and methods that worked for traditional post-printing can’t keep up with the growing demands. Manual support removal, whether it’s hand tools, soak tanks, or rinse baths, slow down the entire process.

Technicians spend hours clearing geometry, waiting for parts to dry, or reprocessing components due to inconsistent results. And with labor costs rising, relying on manual intervention is neither sustainable nor scalable. These delays not only limit throughput but also create unpredictable lead times, impacting overall operations.

Intelligent Automation for High-Throughput Workflows

The PostProcess BASE™ solution brings precision, consistency and speed to FDM post-processing. Purpose-built for high-volume FDM production, BASE uses a spray-based technology that eliminates the need for prolonged soaking and overnight drying. It automatically adapts to part geometry and material type to optimize cycle times without sacrificing quality. That means more parts out the door – faster, cleaner, and with less labor.

Key benefits include:

• Reduced cycle times: Complete support removal in under an hour, with no drying required
• Labor savings: Hands-off operation with minimal technician oversight
• Improved consistency: Reliable results regardless of part complexity
• Scalability: Designed to support multiple builds per day, with no compromise on performance

Built to Complement Industrial FDM Printers

Our solutions are purpose-built to align with the throughput capabilities of many of today’s industrial FDM printers, such as the Stratasys F3300, F900, or Fortus series.

By integrating the BASE into your production environment, you can create a seamless, end-to-end workflow. Instead of slowing down workflows to wait on soak tanks or oven drying, parts can move directly from printer to post-print in a continuous, accelerated process.

Whether you’re producing large-format jigs and fixtures, high-strength production parts, or daily prototype runs, this pairing ensures that your investment in high-end printers is maximized to the fullest.

A Smarter, Scalable Future for FDM

Whether you’re printing 50 or 500 parts a week, automated post-processing can help unlock the full potential of your additive production line. By removing the burden of manual labor and unpredictable cycle times, you free up valuable capacity and create a workflow that’s built for growth.

At PostProcess Technologies, we’re here to support that growth – with an automated solution that’s engineered to meet the demands of high-volume FDM.

There has become a need to minimize human exposure to IPA through automated cleaning stations and safety protocols to ensure safer working conditions. Adopting these advanced systems not only protects workers but also ensures compliance with safety standards across industries.

4. Speed and throughput are key

After 3D printing, the post-printing step has traditionally become a bottleneck in large-scale  workflows. However, the demand for faster production cycles means post-processing technology must keep up with 3D printing technology. If 3D printing is already automated, why not automate the next step?

Advances in high-throughput depowdering, cleaning, and finishing technologies are allowing manufacturers to speed up production without sacrificing quality. The push for faster, more scalable solutions is driving innovation to reduce cycle times, enabling quicker delivery to market.

5. Quality control is a must

As additive manufacturing evolves, the demand for consistent, high-quality parts has never been greater. This means post-processing companies will need to provide solutions that offer better quality control. Advances in AI-driven quality checks and automated inspection technologies are allowing manufacturers to ensure that parts meet exact specifications every time. As quality assurance becomes even more critical in industries like healthcare and aerospace, these innovations will become non-negotiable.

Conclusion

Post-processing is no longer an afterthought in 3D printing – it’s a critical part of the production process that directly impacts the quality, cost, and efficiency of the final product.

As we move through 2025 and beyond, embracing automation, sustainability, safety, and cutting-edge technologies will be essential for staying competitive and meeting the growing demands of the industry.

In today’s manufacturing landscape, the terms “3D printing” and “additive manufacturing” are often used interchangeably. But are they truly the same? While they share similarities, there are key distinctions between the two. This blog will help you understand the relationship between 3D printing and additive manufacturing and when to use each term.

What is 3D Printing?

3D printing refers to the process of creating a three-dimensional object from a digital model, such as a CAD (Computer-Aided Design) drawing. This technology has revolutionized how objects are designed and produced. The process involves slicing the digital model into thin layers, which the 3D printer then builds up layer by layer using various materials.

Here are some of the most widely used 3D printing technologies:

• Fused Deposition Modeling (FDM): This method extrudes thermoplastic filament to build an object layer by layer.
• Selective Laser Sintering (SLS): A polymer powder is preheated to its melting point and then selectively fused together by a CO2 laser to create a solid part.
• Stereolithography (SLA): In this process, a photosensitive liquid resin is solidified using an ultraviolet laser.
• PolyJet: This technology uses liquid photopolymers and builds parts by depositing ultrafine droplets onto a build platform.

3D printing is commonly associated with small-scale, one-off productions and is often used in prototype development or by hobbyists.

What is Additive Manufacturing?

Additive manufacturing (AM) encompasses 3D printing but goes beyond just the printing process. It refers to an entire industrial manufacturing process that includes not only the creation of objects but also several other essential steps. While 3D printers play a crucial role, additive manufacturing involves a broader, more complex workflow.

The additive manufacturing process can include:

• Modeling: Developing a digital design using CAD software.
• Material Traceability: Ensuring the materials used are tracked and meet quality standards.
• Workflow Management: Coordinating the various stages of production.
• Post-Processing: Finishing techniques such as painting, polishing, or heat treatments to enhance the final product.
• Quality and Inspection Systems: Rigorous checks to ensure that the final product meets all necessary specifications.

Additive manufacturing is typically used in large-scale or industrial applications, where precision, consistency, and scalability are crucial. This workflow can look vastly different than a typical small-scale 3D printing process.

Understanding the Difference

While 3D printing is a subset of additive manufacturing, not all 3D printing is considered additive manufacturing. The key difference lies in the scope and application. 3D printing usually refers to smaller-scale operations, often at the consumer or hobbyist level. In contrast, additive manufacturing refers to a comprehensive production process used in industrial settings.

Key Takeaways:

• 3D Printing: Ideal for small-scale, prototype, or hobbyist applications.
• Additive Manufacturing: Involves a full production workflow and is used in industrial and large-scale manufacturing contexts.

When choosing which term to use, consider the context. If you’re referring to a process with multiple steps in an industrial setting, “additive manufacturing” is the appropriate term. For smaller-scale or one-off productions, “3D printing” is more accurate.

By understanding these differences, you can better navigate the evolving landscape of modern manufacturing and use the right terminology for your needs.

In resin-based 3D printing, post-processing is crucial for high-quality parts. After photopolymer resins are cured, printed objects are often covered in excess resin that must be removed before further post-processing steps. Traditionally, this is done by manually submerging the parts in isopropyl alcohol (IPA) and scrubbing them, which is both labor-intensive and risky for the overall environment.

IPA poses significant challenges in additive manufacturing due to its flammability, which increases workplace accident risks and releases volatile organic compounds (VOCs). These VOCs degrade air quality and can cause respiratory issues. Additionally, the repetitive task of scrubbing parts with IPA can lead to technician fatigue and inconsistencies in part quality.

Addressing Safety and Efficiency

To tackle these challenges, PostProcess Technologies has developed automated solutions that eliminate the need for IPA by combining innovative hardware, proprietary software, and additive-specific chemistries. They have engineered a workflow that effectively cleans excess resin while addressing safety and environmental concerns.

In this process, printed parts are placed into a DEMI system which utilizes Submersed Vortex Cavitation technology and PLM-403-SUB detergent. This system efficiently cleans the parts, removing residual resin from the printing process. However, a final rinse step is necessary to prepare parts for curing and/or additional cleaning steps.

IPA has traditionally served as the final rinse step, but it has an incredibly low flashpoint, which makes it a hazard to any facility, and as previously mentioned, some facilities and countries will not allow IPA to be used at all in their facilities.

How to Eliminate IPA from Resin Post-Processing

To completely eliminate IPA from the resin removal workflow, PostProcess has developed AUX-400-RINSE. This organic-based rinse solution can be used as a final rinse step following processing in PostProcess automated resin removal solutions.

PostProcess conducted comprehensive testing of AUX-400-RINSE, focusing on flashpoint, drying time, safety, longevity, and material compatibility. The findings revealed that AUX-400-RINSE surpasses industry safety and performance standards and also sets a new benchmark for post-processing excellence.

The full PostProcess resin removal workflow, featuring AUX-400-RINSE, streamlines operations, reduces manual labor, and ensures consistent part quality, promoting regulatory compliance and a healthier work environment.

Pioneering a Safer Future

The development of AUX-400-RINSE highlights PostProcess Technologies’ commitment to advancing industry standards through safer and more efficient solutions. Manufacturers can improve safety, enhance environmental practices, and achieve operational efficiency by adopting IPA-free resin removal methods.

AUX-400-RINSE provides a significant reduction in overall safety hazards due to the high potential for IPA fumes to spontaneously combust at low temperatures, which poses a risk of injury to employees and creates a hazard to the overall facility’s environment. Both chemistries used in PostProcess’ resin cleaning workflow provide increased safety. AUX-400-RINSE has a 21% lower vapor pressure than IPA, reducing flammability risks, and PLM-403-SUB offers a significantly higher flashpoint of 220°F / 104.4°C compared to IPA’s flashpoint of 53°F / 11°C.

Elastomeric resins are a class of polymer materials known for their elasticity, which allows them to regain their original shape when distorted. Examples include natural rubber, polyurethane, polybutadiene, neoprene, and silicone. Consumer goods, automotive, and industrial are a few of the key industries using elastomeric resins in the market.

The number of elastomeric resins is also growing rapidly, with 45 different types and more to come in the future. However, like other 3D printed materials, elastomeric resins pose significant challenges in the post-processing step. It can be difficult to remove the uncured resin without impacting the cured resin. Solvent soaks, such as isopropyl alcohol (IPA) or tripropylene glycol monomethyl ether (TPM) can alter elastomeric properties, causing breakage, swelling, cracking, or loss of elasticity.

Introducing PostProcess Elastomeric Resin Cleaning Solution, PLM-501-SUB™

To address these challenges, PostProcess Technologies has created a new elastomeric resin cleaning solution featuring an all-new additive-specific chemistry, PLM-501-SUB. This is an organic-based resin cleaning solution for VAT-based 3D-printed elastomeric parts. PLM-501-SUB is specifically formulated to remove uncured resin from elastomeric materials while minimizing swelling, damage, or changes to mechanical properties.

This full-stack solution integrates hardware, software, fixtures, and proprietary chemistry to remove resin from many 3D printed plastic materials, effectively cleaning parts from elastomeric materials while minimizing overall part damage.

PLM-501-SUB is designed for use in PostProcess’ DEMI 400, X 520, 800, and 900 Series solutions. These solutions provide a completely IPA-free elastomeric resin cleaning system, integrated with PostProcess hardware, AUTOMAT3D software, allocated fixtures, PLM-501-SUB, and rinsing with AUX-400-RINSE.

After elastomeric parts are submerged in PLM-501-SUB, they can then be rinsed with PostProcess’ AUX-400-RINSE if a final rinse step is necessary before they are dried and/or cured.

Why Choose PLM-501-SUB?

Odorless and Organic: PLM-501-SUB™ is an odorless, organic solution with a 30% longer lifespan compared to IPA and TPM.

Enhanced Safety: It provides a safer alternative to solvent soaks like IPA, with a high flashpoint (237°F / 115°C) to significantly reduce flammability risks. Unlike IPA, it does not require explosion-proof or ATEX-certified equipment.

Efficiency and Speed: Elastomeric resin is removed within 5-7 minutes when components are submerged in PLM-501-SUB™ using a PostProcess SVC solution. This eliminates the need for manual labor and achieves superior efficiency, with 35-38% longevity in terms of resin by weight.

High-Quality Output: By integrating PLM-501-SUB™, manufacturers can protect elastomeric parts from swelling or cracking, resulting in a higher quality end-product and increased throughput production of quality parts.
