3Dprinting advancements and applications have gone from conformally cooled hot runner nozzles using a 3D-printed pattern to cast the part with integrated cooling circuits (left) to large DMLS 3D-printed parts in 420 stainless steel with integrated conformal cooling and InnoVent Technology for venting (right).
But while reduced cycletimes and improved part quality resulting from cooling advances were once the primary reason that AM made its way into moldmaking, 3Dprinting is now also being used to make molds for different reasons — including cost, leadtime and feature complexity as I saw at this year’s Plastics Technology Expo, or PTXPO.

Source (All images) | APSX As moldmakers face increasing pressures to deliver faster and more cost-effective solutions, integrating 3Dprinting (3DP), machining and desktop injection molding into the process can offer significant advantages for both novice and advanced moldmakers.
Additive manufacturing (AM), more commonly known as 3Dprinting, is an innovative process where objects are created one layer at a time. AM delivers agility, consolidation and savings on lead-times, costs and resources. 3DPrinting in Action. FALLS CHURCH, Va., SOURCE: Northrop Grumman.
AION NX – India’s first large format hybrid 3D printer has the speed of 3Dprinting & accuracy of a (Computerized Numerical Control) CNC machining . Divide by Zero Technologies (DBZ), one of India’s leading3D Printer manufacturers, has launched AION NX, the next frontier in large format hybrid 3Dprinting.
What does that mean for the qualification of 3Dprinted parts? is to leverage additive manufacturing to reduce maintenance cycletimes, curb supply chain backlogs, and place manufacturing capabilities at or near the point of need. Most of these printers capable of printing green bin parts are polymer.
The term, “hybrid,” refers to a machine tool that is also something more — usually it connotes combining additive manufacturing (AM) and the machine tool’s normal work of “subtractive” machining within a single machine able to mix both operations in a single cycle.
Also, cycletime, cooling and part ejection issues become more critical when moving to large-scale production, as they can significantly impact productivity and cost efficiency. This vertical integration allows Accumold to hold quick leadtimes and efficiently collaborate to solve problems and produce quality products.
milling, hobbing and grinding) in one machine and systems that use a sub-spindle or multiple axes to machine parts in a single setup to reduce cycletime and minimize geometric and shape defects. .” As examples, Wigington cites turning centers that combine multiple operations (e.g., military bases).
Additionally, there is growing interest in additive manufacturing (3Dprinting), which is gaining traction for producing complex, lightweight components, especially in aerospace and defence industries. The market for CNC (Computer Numerical Control) machines is expanding rapidly, driven by the automotive and aerospace sectors.
Current as of 2/01/23 This article contains information on exhibitors highlighting 3DPrinting , Machining or Cutting Tools products and services at their booth in the Moldmaking Pavilion and across the show floor. 3DPrinting Get to Know Mantle 3D Moldmaking is at the core of what Mantle does.
For example, shops pay more attention to a mold’s thermal dynamics during design, molding and preventative maintenance (PM) to reduce cycletime, decrease energy consumption, improve plastic part quality and increase yield. Lower cycletimes and lower scrap rates equate to higher part production.
It also reduced maintenance costs, tool costs (30-40%) and tooling leadtimes (20-30%). This is unfortunate since tool production — especially hard/metal tools — can have long leadtimes and add considerable cost to the bottom line. Similarly, for thermosets, heating lines can be created to speed curing times.
Hybrid manufacturing solutions that combine additive and subtractive processes were also highlighted, offering moldmakers new ways to create complex geometries and conformal cooling channels that can significantly improve mold performance and cycletimes. 3DPrinting Sector: Busy with diverse materials and software solutions.
End-to-End Conformal Cooling Design, Production for Faster CycleTimes, Boosted Part Quality. Cooling is a critical process for plastic injection molds, affecting both cycletime and final part quality, Cimatron notes, but is especially challenging for complex parts when using traditional drilling and milling methods.
Moldmakers are embracing automation, robotics and advanced machining to boost precision, cut leadtimes and extend mold life. When it comes to 3Dprinting, we have Next Chapter Manufacturing pushing additive manufacturing for conformal cooling and venting to improve cycletimes and part quality.
based FET is growing and changing to fit the needs of the molding marketplace for shorter cycletimes and lower weight parts — this is particularly true for the growing electric vehicle (EV) market. This has enabled Plastek to provide high-quality, dependable molds with reliable and short leadtimes.
Given the diverse scope of tool builds — ranging from single-cavity prototypes to four-cavity bridge tooling to multiple high-cavitation molds (16, 24, 32, 48, 64, 96, 128, etc.) — leadtimes vary accordingly. This internal capability allows Dynamic Tool to manage leadtime and avoid outsourcing bottlenecks.
Mastip cold decks are optimized to shorten cycletimes while producing high-quality parts. Stress-relieving heat treatment therefore reduces leadtimes, increases precision, results in cost savings and thus provides a competitive advantage in the long term for Meusburger’s customers.
Over the last few years, after witnessing the growth of 3D additive metals for productions molding, PLT has engaged with manufacturers and their materials to train staff and establish proven techniques to service laser requests similar to traditional tooling. In the past few years, the company has focused on metal 3D for molding.
