PrintCity uses Fusion 360 and Formlabs’ Form 3 3D printer to provide custom additive manufacturing workflow and material solutions to customers. In this post, we take a deep dive into how they developed a scan to CAD workflow for United Utilities.


PrintCity is a 3D additive manufacturing and digital manufacturing facility based in Manchester, UK, a city with a rich industrial history. Based within Manchester Metropolitan University, the facility serves as an education and consulting hub for companies in Manchester and internationally. PrintCity is also a campus fabrication space for students in the university’s MSc in Industrial Digitalization program.

PrintCity currently has 65 printers of various types, representing FDM, SLA, and metal printing technology. The staff at PrintCity consults with companies of all sizes on which digital technologies they should adopt in their own organization and helps guide products through R+D and manufacturing stages.

We recently spoke with PrintCity product development specialist Mark Chester to discuss how the company uses accessible tools like Fusion 360 and Formlabs Form 3 printer to help his clients embrace and leverage digital fabrication. In this article, we’ll take a special look at the UK’s largest water company, United Utilities as a case study.

PrintCity Consults With Clients of All Sizes

PrintCity’s diverse fleet of 3D printers is always a starting point for discussing digital tools with clients. Chester says that “companies that come in to see us have sometimes never accessed 3D printing before, and they are completely new to this type of technology. So it’s important for us to share a wide spectrum of printers available.” Mark works with companies ranging from textile designers to sports equipment companies, to utility providers, to manufacturers. Although these companies differ in size and product category, he sees many common threads in their needs and the solutions that tools like Fusion 360 and the Form 3 bring to the table.

One common theme of Chester’s work is to break a problem down into smaller parts, so you can go through multiple iterations on the same day rather than taking a week or more. Ultimately this reduces time to market. To address this need, PrintCity staff can print same-day prototypes for a client on an FDM machine or Form 3 with Draft Resin, then later move to higher fidelity iterations with Formlabs Standard or Engineering Resins

Many companies’ designs are destined for injection molding for mass production, and the Tough and Durable family of Formlabs resins can be a good mimic for end-use parts. However, an increasing number of clients are thinking about additive manufacturing for end-use. In one recent example, Mark evaluated Rigid resin for a company that designs embossing rollers for impressing textures into paper media. The client specifically required a high-fidelity textured part in a high-strength material.

 “Fusion 360 has a shallow learning curve for clients who don’t have previous CAD experience. It’s cost-effective as well.”

In addition to physical outcomes, accessibility is also key. “I think for all companies, one of the barriers is always money. We always need to do a cost-benefit analysis to see if adopting a certain technology will benefit your company.” The Form 3 fills a need for an approachable desktop solution that delivers professional results. The same can be said for Chester’s CAD tool of choice, Fusion 360, which he uses for client and personal projects. “Fusion 360 has a shallow learning curve for clients who don’t have previous CAD experience. It’s cost-effective as well.” Chester commented that Autodesk is also consistently updating its software with new features and pushing those features to customers. “Autodesk is always listening to their customers.”

Another unique challenge arises when working with larger companies: Mark sometimes sees resistance to change. A team that has successfully relied on the same workflow for many years can often be hesitant to try something new. Mark will frequently offer to conduct a feasibility study to reduce the fear and risk associated with change. These research studies help answer fundamental questions about whether technology will have the intended outcome and integrate seamlessly into an organization.

Creating On-Demand Replacement Parts with the Form 3 and Fusion 360

United Utilities, the UK’s largest water company, contacted PrintCity for a feasibility study to identify technologies that could improve their core services. Mark worked with the utility company’s Continuous Improvement team to investigate ways to produce replacement parts for repairing mechanical assemblies quickly. If issues arise in the field, a replacement for a broken part can take days or weeks to be delivered, resulting in service interruptions for customers. Perhaps 3D scanning and 3D printing could enable the manufacture of functional replacement parts on demand. For this feasibility study, PrintCity needed to evaluate three technologies: the scanning method, the printing process and materials, and the CAD software that links these two physical steps together.

Replacement part for a United Utilities flow meter: raw data from a 3D scan, and the cleaned-up parametric model from Fusion 360.

Chester’s proposed workflow started with scanning a worn part with a tripod-mounted laser scanner called the Hexagon Absolute Romer Arm, capturing high surface detail in the process. Next, he imported the raw data into Autodesk Fusion 360. Scan data can technically be converted directly to an STL for 3D printing. However, the raw data alone is not likely to form a watertight part that is suitable for additive manufacturing. The key feature of Fusion 360 that Mark used was the Mesh Workspace, enabling users to directly import and clean up the scan. Fusion 360’s powerful parametric modeling tools also allowed Chester to reverse engineer a crisp new part that matched the precise geometry needed for end-use.

From Fusion 360, the parts were taken straight into Preform for print preparation and then printed on a Form 3. Using this integration between Fusion 360 and Preform, a maintenance crew from United Utilities can import a scan, clean up, and print parts on the fly without saving STL files for dozens of single-use parts. 

As part of the study, PrintCity also introduced the client to a range of material properties from Formlabs’ resin library. Draft Resin was a good choice for high-speed form and fit prototypes, and they also introduced end-use samples in the Tough and Durable family of resins and Rigid Resin. These resins mimic the mechanics of plastics commonly used in the water service industry, such as Acetal and ABS.

“The quality of the 3D printed products produced was excellent. [We’re] really impressed by how quickly PrintCity manages to get the gear turned around when changes need to be made.”

Autodesk Fusion 360 and the Form 3 enable Chester’s team to quickly identify a feasible workflow and present it to their clients, no matter the size of the organization. At the end of this feasibility study, Mark delivered a report to United Utilities detailing the digital workflow of the 3D scan to 3D print and the associated costs. At this point in the study, the 3D printed parts appear to function just as well as the originals.


Collaborating Remotely with Fusion 360

Working remotely has been the standard for many workplaces during 2020 and early 2021. For PrintCity, following social distancing recommendations was challenging for a business model that normally relies on in-person demos and meetings. “With 3D printing, you really need to hold and see the 3D print. That has been missing over the last year or so. With a lot of our clients, once they have a 3D print in their hand, they have a lightbulb moment where they say, ‘this is exactly what we need.’”

In the meantime, PrintCity has been relying on the mail to deliver prototypes to clients. To some extent, technology has helped bridge the gap between Mark and his clients. One particular benefit of Fusion 360 can digitally share files with customers through the cloud. “We can send a link to a client with a 3D model. They can look around it, provide comments, or even download it.” 

Bridging Education and Industry

In addition to learning directly from PrintCity’s staff, companies can tap into some of the great student talents at MMU. Often after completing a feasibility study with a client, a logical way to step forward is to match a student with that company for an internship position. According to Mark, “we can do a bit of what we call ‘reverse mentoring’ where students can teach the skills they have learned, and bring [those skills] into the company.” Many students even go on to get their first jobs at these companies while leveraging accessible digital tools like Fusion 360 and the Form 3.

Mark left us with some great advice for product developers tackling new problems. He says it’s common for a company to have a specific 3D printing technology in mind and then steer in a different direction after exposure to many different technologies. “Gain experience, fail fast, and fail often. What might fail for one product or project might work well for another.”
