ExOne has changed hands three times since 2021 — Desktop Metal (2021), Nano Dimension (2024), and the October 2025 combination with voxeljet under ExOne Global Holdings. Each transition has had real effects on ExOne customers. Foundries report three recurring issues that are driving them to evaluate alternatives.<\/p>\n\n
First, support response times have lengthened. Where ExOne historically responded to critical service requests within 24 to 48 hours, some foundries now report 72 to 96 hour response times for non-contract customers, and longer for parts availability. For a production foundry running 2 shifts, every hour of downtime costs $200 to $500 in lost throughput, not counting the downstream casting delays.<\/p>\n\n
Second, spare parts pricing has increased. Post-merger restructuring has led to revised parts catalogs and pricing updates. Foundries report 15 to 30 percent increases on common wear parts (print heads, recoater blades, build plate assemblies) compared to pre-2022 pricing. For a machine running 2 shifts, annual parts spend can reach $15,000 to $30,000, so a 20 percent increase is a material cost change.<\/p>\n\n
Third, the product roadmap is uncertain. ExOne has not announced a successor to the S-Max Pro, and the S-Print Pro compact machine, while welcome, does not address the needs of mid to large format foundries. Foundries investing in a 7 to 10 year asset want confidence that the manufacturer will continue to develop the platform. This uncertainty is a primary driver for foundries evaluating 3DPTEK as an alternative.<\/p>\n\n
The Transition Path: Moving from ExOne to 3DPTEK<\/h2>\n\n
If you are currently running an ExOne machine and considering a transition to 3DPTEK, the path is more straightforward than you might expect. The core technology (binder jetting) is the same, the sand materials are compatible, and the mold quality specifications are equivalent. The transition involves three steps.<\/p>\n\n
Step one is process validation. Send your typical part CAD files to 3DPTEK, and we will print the molds on a J-series machine, cast the parts in our own foundries, and ship you the finished castings for quality comparison. This typically takes 2 to 3 weeks and gives you a direct side-by-side comparison of dimensional accuracy, surface finish, and casting quality between your ExOne process and the 3DPTEK process. Start with a rapid prototype casting<\/a> to begin this validation.<\/p>\n\nStep two is material qualification. If you have existing inventory of coated sand or binder, we test it on the 3DPTEK machine to confirm compatibility. Most commercially available furan and phenolic coated sands work without modification. If your sand requires a specific binder chemistry, our process engineering team adjusts machine parameters to match. This step typically takes 1 to 2 weeks.<\/p>\n\n
Step three is installation and training. The 3DPTEK machine is installed alongside your existing ExOne (or as a replacement), and your operators are trained on the new system. Because the fundamental process is the same (binder jetting), operator training focuses on software differences, maintenance procedures, and process parameter tuning. Most foundries are fully operational on the 3DPTEK machine within 1 to 2 weeks of installation. See our foundry integration guide<\/a> for the full timeline.<\/p>\n\nFuture-Proofing: Why an Open System Ages Better<\/h2>\n\n
A sand 3D printer is a 7 to 10 year investment. The material system you choose today determines your operating cost for the next decade. An open system like 3DPTEK ages well because it adapts to new sand formulations, new binder chemistries, and new process improvements without hardware changes. A closed or semi-closed system like ExOne ties you to whatever the manufacturer chooses to support, at whatever price they choose to set. When the manufacturer goes through mergers and acquisitions, the material roadmap becomes even less predictable. Foundries that bought ExOne machines in 2020 did not anticipate the Desktop Metal acquisition and its effects on consumables pricing and support. An open system removes this risk entirely.
