3D printing reduced four parts to two. Manufacturing cost was dramatically reduced because there was no assembly and none of the tooling that would have been required for the three plastic parts combined with the bearing. Slant 3D is using this approach to develop a “fidget spinner” with an internal bearing.
A growing number of injection molders have adopted 3D printing for prototyping or making conceptual models to present to clients. Some are even making 3D-printed parts for internal use, such as jigs, fixtures, or robot grippers.

They utilize an FDM-type of process in which extruded thermoplastic filaments are deposited in thin layers. Called the SlantBox, these “commoditized” printers are mounted in racks and all connected to the cloud for maximum productivity. They have a build volume of 10 by 8 by 9 in. and precision of 100 to 300 microns. They are designed to run continuously with much greater reliability than standard 3D printers. “We design them to be assembled and implemented quickly, but also rigid and tough enough to produce 95% good parts,” Bentz says. By addressing typical 3D manufacturing defects stemming from bed inconsistency or nonuniform extrusion rates, Bentz claims his production is more consistent from part to part and throughout an individual part than is commonly found in the market.

“3D printing allows an idea to go from conception to manufacture quickly and much more affordably. There are no tooling costs or lead time. A company wishing to produce a product need only design it and then pay for the raw materials used to produce it. 3D printing puts physical products on equal footing with software products in production costs. Printing allows products to be produced at very low cost and constantly updated with no large capital expenditures.”

3D printing can make “impossible” parts like these gear shafts with a metal bearing inside. The gear, toothed pulley, and shaft are one plastic part that was built around the bearing instead of manufactured separately.
But since this part was 3D printed, the gear, pulley, and shaft were combined into a single part. During production, the build would pause to insert the metal bearing. Then the build would continue and the part would be built around the bearing.
At some point in our lives, nearly all of us will rely on a consistent form of transportation to help us in our daily activities...
Across all process types, sustainability was a big theme at NPE2024. But there was plenty to see in automation and artificial intelligence as well.
Introduced by Zeiger and Spark Industries at the PTXPO, the nozzle is designed for maximum heat transfer and uniformity with a continuous taper for self cleaning.
Injection molded parts for this assembly would have to be designed to interlock and pull apart so that a bearing could be inserted. In this case, what is now manufactured as a single assembly would have to be split into the gear, toothed pulley, shaft, and metal bearing, all of which would be manufactured separately and then assembled together.
Implementing a production monitoring system as the foundation of a ‘smart factory’ is about integrating people with new technology as much as it is about integrating machines and computers. Here are tips from a company that has gone through the process.
Second quarter started with price hikes in PE and the four volume engineering resins, but relatively stable pricing was largely expected by the quarter’s end.
“We are working to make 3D printing a large-scale manufacturing option,” says Bentz. “We are doing this by developing hardware, software, and techniques to allow 3D-printing devices to produce parts in volume.”

But few have pursued this technology as a means of commercial production of custom parts. For the most part, injection molders have left that field open to companies specializing in low-volume, high-value parts for aerospace and medical uses.
According to Bentz, price isn’t the only reason to consider 3D printing. “Traditional manufacturing techniques,” he says, “require high up-front expenses for tooling and long-term, high-volume production of a component to amortize those initial expenses. But if there is a mistake in the product, or the market changes, so that the product must be modified, companies may lose the entire investment in molds and tooling. This high risk also makes entry into high-volume production challenging for small or new businesses.
Successfully starting or restarting an injection molding machine is less about ticking boxes on a rote checklist and more about individually assessing each processing scenario and its unique variables.
Ultradent's entry of its Umbrella cheek retractor took home the awards for Technical Sophistication and Achievement in Economics and Efficiency at PTXPO.
However, Slant 3D has produced some structural parts. The key, Bentz notes, is that such parts must be designed specifically for 3D printing, not simply converted from an injection molded design. He adds that 3D printing has advantages for making so-called “impossible” parts. An example is the gear shafts shown in the photo above. They are built around a metal bearing, making the entire assembly effectively a single part.
While prices moved up for three of the five commodity resins, there was potential for a flat trajectory for the rest of the third quarter.

Comparison of injection molding and 3D printing costs. It is assumed that the injection mold costs $5000 and the cost per part, exclusive of mold-amortization, is 20¢. Total cost per molded part, including mold amortization declines with volume, while 3D-printed part cost is constant at an assumed 70¢.
Despite price increase nominations going into second quarter, it appeared there was potential for generally flat pricing with the exception of a major downward correction for PP.
There are growing signs that injection molders need to watch their backs. Innovative start-up companies are emerging with large “farms” of 3D printers organized to compete with injection molding for orders of 10,000, 20,000, or even 100,000 parts. We reported in a September 2017 Close-Up on one example of this new type of competition, Voodoo Manufacturing in Brooklyn, N.Y. That article brought a response from a similar new venture, clear across the country. We were contacted by Gabe Bentz, president and founder of Slant Concepts in Nampa, Idaho. His mechanical design and engineering firm had spun off a second venture in October 2016, called Slant 3D, devoted to custom 3D printing in small to medium volumes. He claims it can produce parts that are less expensive than injection molding in volumes under 10,000 parts and reasonably competitive in price at up to 20,000 parts (see accompanying chart).
Say “manufacturing automation” and thoughts immediately go to the shop floor and specialized production equipment, robotics and material handling systems. But there is another realm of possible automation — the front office.

What’s more, he notes, his printers are fully automated so they can operate 24/7 without human intervention. “We have no need of robotic systems, because our printers remove the parts themselves (free dropped into bins) and are still lower cost to produce than most desktop 3D printer kits.” Bentz expects to begin marketing the SlantBox to others in the near future, at an anticipated price of $1000 to $1500.

Bentz concedes that surface smoothness is one area in which injection molding has an advantage over most 3D printing. Because 3D printed parts are typically produced in a sequence of layers, they can be weaker in the Z-direction than injection molded parts.
