Over the years, blacksmiths, broiler makers, and ironworkers have been called metal fabricators. But in today’s world, where technology has advanced, it is hard for an individual to make machine parts alone. So today, large companies known as metal fabricators or metal part fabricators do this forging instead of the custom humans. Having said this, a metal fabricator is a company that designs, constructs and installs metal works.
These companies fabricate metals parts using raw materials like cast metals, welding wires, rods, expanded metal harnesses, and different cutting, bending, and assembling methods.
Metal parts fabricators fall into two main groups based on their method of operation. Those that produce and trade parts fall into the class of factory and trade integration; Protolabs is an example. Those that deal only with connecting customers with several manufacturers come under the class of pure trading; Xometry is an example. Continue reading to know which of the companies is best for your project.
Metal Manufacturer Contrast: Protolabs Vs Xometry
Protolabs and Xometry are good fabricators, so picking which one to do business with could be challenging. We will examine the critical criteria to consider when choosing one of them, and by the end of this, you will know which of the two fabricators will soothe your needs.
Quotation: winner Xometry
When you work with Protolabs, you start by providing a 3D CAD model of your part. Using this, they’ll give you a quote that’s valid for 30 days. Keep in mind that prices can change after this period without notice. Protolabs also reserves the right to correct any clerical or typographical errors in the quote. If there are discrepancies between the 3D CAD data and the 2D sketch, they’ll make the necessary adjustments. When requesting a quote, make sure you specify any threads or tolerances and confirm that these are accurately reflected in the quote.
On the other hand, Xometry makes the quoting process quick and easy with their AI-powered platform. You can get instant quotations that include immediate pricing, lead times, and Design for Manufacturability (DFM) feedback. This means you’ll have access to the production capacity of over 10,000 manufacturers with capabilities like CNC machining, 3D printing, sheet metal fabrication, injection molding, and laser and sheet cutting. After generating your quote, Xometry’s engineers will review your project and pass it on to highly vetted suppliers within their network.
Quality Control: Winner Protolabs
Protolabs uses digital processes, inspection reporting, and scientific molding to consistently produce high-quality molded parts. When you request an injection molding quote from Protolabs, they provide a design analysis that helps streamline the molding process. This analysis helps you avoid costly redesigns, saves time, and eliminates guesswork. Before placing an order, you’ll know if your design needs any changes and receive guidance on improving its manufacturability.
On the other hand, Xometry employs intensive processes to ensure the highest manufacturing standards for your parts. Since Xometry partners with various manufacturers rather than producing parts in-house, they focus on inspecting the dimensions and visual aspects of your parts during and after the project. This ensures that you receive accurately designed components on time.
In-house Machining Capabilities: Winner Protolabs
Protolabs uses CNC milling to create custom prototypes and end-use manufacturing parts in just one day. They utilize 3-axis and 5-axis milling processes to make parts from more than 30 engineering-grade metals and plastics. You can rely on their in-house CNC milling for functional prototypes, jigs and fixtures, and low-volume manufacturing components. Their CNC turning service also produces custom prototypes and end-use production parts daily. With a CNC lathe equipped with live tooling, Protolabs can machine features like flats, radial holes, grooves, and slots.
As for Xometry, they partner with over 10,000 suppliers, giving them access to a wide range of manufacturing capabilities. Xometry suppliers use CNC turning for CNC machining services. For 3D printing, Xometry employs various technologies like HP Multi Jet Fusion, fused deposition modeling, stereolithography, and selective laser sintering.
Price and Lead Time: A Tie
When comparing Xometry and Protolabs, several key factors stand out. Both companies offer instant online quotes, although Protolabs requires an account for access to their MyRapid service. In terms of 3D printing capabilities, Xometry generally provides competitive pricing across various processes and offers flexibility in CNC machining for smaller batch orders.
However, Protolabs boasts faster turnaround times, sometimes as quick as one day, thanks to their in-house digital manufacturing capabilities. In contrast, Xometry typically requires a minimum three-day lead time for 3D printing and up to 10 business days for standard orders, which may vary depending on the complexity of the project.
Self-owned Machines: Winner Protolabs
Since they produce and trade parts, Protolabs owns over one thousand mill presses and 3D printers that work around the clock to create machine parts. They also have a range of CNC machines at their disposal, ensuring they can meet various manufacturing needs.
In contrast, Xometry boasts a vast network, with over two thousand partners in Europe alone and four thousand partners globally. They also serve two thousand five hundred customers, making Xometry Europe the largest network for CNC machining, sheet metal fabrication, injection molding, and 3D printing
Certification: Winner Xometry
Protolabs holds several important certifications, including ISO 9001:2015 and AS9100D, and they are registered with ITAR. ISO 9001:2015 certification covers their injection molding, CNC machining, sheet metal fabrication, and all 3D printing processes. AS9100D certification specifically covers CNC machining, direct metal laser sintering, and multi-jet fusion.
Similarly, Xometry is registered with ITAR and holds more certifications in ISO 9001:2015, ISO 13485:2016, IAFF 1649:2016, and AS9100D.
Delivery: Winner Protolabs
Protolabs gives you a flexible lead time option, allowing you to control when your CNC part is shipped and how much you pay. If you’re willing to wait 6 to 12 days, Protolabs offers a discounted rate for their flexible manufacturing option, which they guarantee is faster than other suppliers. You can also choose their standard delivery of just three days, or if you’re in a rush, they can ship your part in just one day. Their e-commerce platform makes it easy to choose your delivery option and see the pricing for each.
On the other hand, Xometry provides three production speeds to meet your budget and timeline based on the CAD you upload: Expedite, Standard, and Economy. Expedite is the fastest option with an additional fee. Standard offers the average Xometry fee and lead time, without extra costs or discounts. Economy gives you the lowest cost, but your parts might be made overseas, which takes longer to ship.
Final Verdict: Protolabs Vs Xometry
Although some may prefer Xometry due to their extensive network of companies for parts sourcing, Xometry maintains high standards by selecting only the best partners. Their quality control and instant quotation system are significant advantages. However, Protolabs stands out by not relying on third parties, giving you complete control over your production process. Additionally, Protolabs offers unparalleled delivery speed, with parts available as fast as one day—a level of service unmatched by other metal part fabricators.
