What are recyclable resins?

A research team at the University of Birmingham has developed a resin made from bio-sourced materials that can be recycled and reused. Unlike conventional petrochemical-derived photopolymer resins, recyclable resins lack permanent chemical bonds that make them easier to recycle. As such, this new resin can be broken down and reprinted with minimal additives, creating a near closed-loop system that makes 3D printing prototypes more sustainable and practical.

What are they made of?

The resin is made from a recyclable material based on lipoic acid (a naturally occurring fatty acid). Researchers created it by combining two monomers that allow the resin to be broken back down into its original molecules. It went through two full recycling cycles without losing quality during testing, suggesting it could be reused even more times in future.

Recyclable vs traditional resins

Photopolymer resins have largely been produced from petrochemical sources since the 1980s. Despite their reliable performance, they come with environmental challenges, from high energy requirements to limited recyclability. Meanwhile, bio-based recyclable resin can be broken down efficiently and reused, making it a more sustainable choice.

Uses of recyclable resins

Industries that rely on rapid prototyping stand to benefit most from 3D printing prototypesusing recyclable resins. Various fields, from automotive and medical to dental, even jewelry design, are already using recyclable resins to reduce their environmental impact. With further improvements to mechanical properties, these materials could support even wider industrial applications in the future.

Shaping the future of manufacturing

The University of Birmingham Enterprise has already filed a patent for this resin and its application in 3D printing. By making recycling part of the process, this development pushes manufacturing closer to a circular model where materials are reused rather than discarded.

Top 7 Industries That Rely on 3D Printing Prototypes for Innovation

From being a niche tool for hobbyists, 3D printing has become a vital technology driving progress in some of the world’s biggest industries. Its ability to create accurate, functional prototypes quickly makes it valuable to many creators and innovators. In this article, we’re looking at how seven different sectors are benefiting from 3D printing prototype services.

Aerospace

Every kilogram affects fuel use and safety on an aircraft. That’s why aerospace engineers are turning to 3D printing to design lightweight parts that are strong enough to endure extreme pressure and temperature. Now, they can make prototypes in a matter of days and test them in simulated flight conditions. The faster iteration cycle helps airlines and manufacturers bring safer, more efficient planes to the skies.

Automotive

Think about the speed at which car makers now release new models and even limited-edition runs. Behind the scenes, 3D printing prototype services are helping designers to create and test anything from engine parts to interior components, and even full-scale models to refine details before production. 3D printing doesn’t need expensive molds, making prototypes easier to produce and test, then modify when necessary. That flexibility allows automotive companies to stay ahead in an industry where innovation cycles are becoming shorter every year.

Manufacturing

3D printing allows manufacturers to print a small batch to gather customer feedback, and then adjust designs before scaling up instead of committing to expensive tooling upfront. It also allows some manufacturers to print specialized fixtures and tools to simplify assembly lines. This streamlines the production process while helping to reduce waste and costs.

Healthcare

3D printing prototype services can help develop patient-specific models to help surgeons plan complex procedures. The technology also makes it possible for researchers to explore bioprinting with human cells and create tissues and even organs.

Robotics

3D printing makes it easy to produce highly specialized parts that are typically complex and expensive to produce with old-school methods. Engineers are free to experiment with designs, test them quickly, and print unique components without breaking the budget. From small prototypes for startups to large-scale automation parts for established companies, 3D printing prototype services help robotics move from concept to reality faster than ever.

Construction

Large-scale 3D printers are already making it possible to print a house. Engineers and architects are using them to build durable structures quickly and cost-effectively. This approach also helps builders reduce material waste and speed up project timelines without compromising quality.

Jewelry design

Jewelry has always been about precision and individuality. 3D printing brings those qualities to a new level by allowing designers to create intricate models directly from CAD software. These models can then be cast into precious metals with flawless accuracy.

The Future of Prototyping: Where Cast Urethane Parts Fit In

Vacuum casting has been part of manufacturing for more than 60 years, and cast urethane parts continue to be a mainstay in product development. It lets designers breeze through design cycles and validate ideas early at a reasonable cost, before committing to full-scale production. Looking ahead, urethane casting will hold its place in prototyping because it lets engineers iterate quickly, makes design changes easy, and keeps small-batch runs affordable.

How is vacuum casting done?

The vacuum casting process begins with a CNC-machined or 3D-printed master model, around which a silicone mold is made. Liquid polyurethane resin is poured into this mold to create precise parts. The finished components can be soft and flexible or rigid and impact-resistant, depending on the resin.

This method for making cast urethane partsworks particularly well for low-volume production and design validation. It also suits bridge manufacturing (the step between prototyping and large-scale production). And while it costs less than injection molding, it still delivers results that look and function like final products.

Beyond the molding process, trusted urethane casting providers can handle part finishing and full assembly, as well as provide visual detailing to ensure that your prototype cast urethane parts are presentation-ready. You will receive functional prototypes that can be tested and showcased immediately.

Why does urethane make sense for prototyping?

Cast urethanes can effectively support fast-paced product development thanks to their technical flexibility and cost advantages:

✅ Lower costs for small-batch production compared to injection molding

✅ A wide selection of materials that mimic everything from rubber to rigid thermoplastics

✅ Faster turnaround from concept to usable prototype

✅ Accurate color matching that matches your pre-production branding

✅ Flexible design iterations, minus the expensive retooling

✅ High-quality finishes that closely resemble production-grade parts

Many service providers also apply sustainable practices, reducing waste and reusing mold materials where possible. This makes cast urethane practical during early design phases and also for making market-specific product lines and accessories after launch. Industries such as medical devices and consumer goods continue to depend on it for both flexibility and speed.

How to Calculate CNC Machining Costs and Reduce Expenses

A CNC machining service can deliver consistent quality with tight tolerances combined with quick turnaround times, making it a reliable choice for businesses that need precision and efficiency. But it’s important to keep machining costs under control to stay competitive and protect your bottom line.

Factors impacting the costs of CNC machining

Understanding what drives CNC machining costs lets you make informed design and sourcing decisions early in the process. Here are the core cost drivers to consider:

The machines and tools involved

Different machines come with different price points. For example, parts produced using 3-axis milling machines or standard turning machines are generally less expensive than those made with 4-axis or 5-axis equipment. The more advanced the machine, the higher the operating and setup costs of the CNC machining service.

The complexity of your design

Intricate designs require longer programming times and advanced machine setups. Parts with tight tolerances and detailed geometries also increase the need for specialized tools and extended machining time. That’s why parts that require high precision or unique features tend to cost more.

Quantity of parts

Production volume directly drives the cost per unit of a CNC machining service. Naturally, a large order costs less due to economies of scale. On the other hand, smaller batches may end up costing more per piece because each batch still requires setup time. Striking a balance between volume and efficiency will keep your expenses in check.

Choice of material

Raw material selection also affects pricing. Some metals and high-performance materials are more expensive and more difficult to machine. Availability and machining properties matter, too —harder materials may take longer to process and wear out tools faster. Always consider both the price and machinability of your material when estimating costs.
