What to Look for When Buying a Used ExOne
ExOne binder jetting systems have unique inspection requirements compared to conventional CNC equipment. Here are the critical checkpoints for evaluating used units.
Inspect the print head assembly and binder delivery system. The print head is the most critical component on any ExOne system. Run a test print pattern to check for clogged nozzles and examine droplet uniformity. Verify binder delivery lines, pumps, and filters for leaks or dried residue. On sand printers, inspect the recoater blade for wear. Ask for the print head's total page count and replacement history.
Evaluate the powder handling and build platform. Check the build box for warping, lifting mechanism wear, and smooth vertical travel. On S-Max and Exerial systems, inspect the sand hopper, overflow bin, and reclaim system for blockages. On metal printers, verify that the atmosphere chamber seals properly and maintains target oxygen levels.
Verify the control system and software licensing. ExOne machines run proprietary control software on industrial PCs. Confirm the software license is current and transferable. Check that the touchscreen interface, motion controllers, and PLC hardware are fully functional. Verify that print parameter files (material profiles) are included, as developing new parameters from scratch is costly.
For metal systems, assess the sintering furnace. Metal binder jetting produces "green" parts that require sintering to reach final density. If a furnace is included, verify heating element condition, atmosphere control, and temperature uniformity. If not, factor that cost into your total investment.
ExOne Sand Printing Systems
S-Max and S-Max Pro
The S-Max is ExOne's flagship sand printer and the most commonly found system on the used market. With a 1800x1000x700mm build volume, it prints large casting molds and cores in silica, ceramic, and chromite sands. The S-Max Pro adds improved print speed and enhanced print head technology. Both serve high-volume foundry operations.
S-Print
The S-Print offers a mid-format build volume for foundries that need sand printing without the footprint of the S-Max. It shares core binder jetting technology with the larger platform and suits prototype casting, short-run production, and job shop environments.
Exerial
The Exerial is ExOne's largest sand printing system, designed for continuous inline operation using multiple build boxes in a conveyor arrangement. It serves large-scale automotive and industrial foundries. Used units are rare but represent significant value.
ExOne Metal Printing Systems
Innovent and InnoventPro
The Innovent series (Innovent, Innovent+, InnoventPro) is ExOne's research-grade metal binder jetting platform with a compact build volume (approximately 160x65x65mm on the InnoventPro). These machines serve material development, parameter optimization, and small-batch production in university, research lab, and R&D settings.
X1 25Pro and X1 160Pro
The X1 25Pro (400x250x250mm build volume) is ExOne's production metal platform, printing parts in stainless steel, tool steel, Inconel, copper, and other alloys. The X1 160Pro scales up to 800x500x400mm for large-format production. Both feature controlled atmosphere printing and high-resolution print heads, carrying strong value on the secondary market.

Frequently Asked Questions About Used ExOne Machines
Are used ExOne machines reliable?
Yes. ExOne built its reputation on industrial-grade systems for production environments, using robust mechanical platforms, industrial PLCs, and proven print head technology. With proper maintenance, these systems deliver consistent results over many years of service.
What is binder jetting and how does it differ from other 3D printing?
Binder jetting deposits a liquid binding agent onto thin layers of powder (metal, sand, or ceramic) to build parts layer by layer. Unlike laser-based 3D printing, binder jetting does not use heat during printing, eliminating thermal stress and warping. Sand-printed molds are ready for casting immediately. Metal parts require post-print sintering to achieve full density.
What should I inspect before buying a used ExOne?
Focus on print head condition (nozzle test pattern, page count, replacement history), powder delivery and recoating system wear, build platform alignment, control software licensing, and overall machine hours. On metal systems, verify atmosphere chamber seals. On sand systems, inspect the recoater blade and sand reclaim components.
What ExOne models hold their value best?
S-Max and S-Max Pro sand printers hold strong value due to high foundry demand. The X1 25Pro also maintains value as one of few industrial-scale metal binder jetting systems available. Machines with current software licenses and documented maintenance histories command the highest resale values. Call (844) 478-8181 for current valuations.
Is ExOne still in business?
ExOne was acquired by Desktop Metal in 2021. The product line, service network, and technology continue under this ownership. Parts, consumables, and technical support remain available.
Can I still get parts and consumables for ExOne machines?
Yes. Print heads, binders, powders, recoater blades, filters, and other consumables remain available through the manufacturer's service network. When purchasing a used ExOne, confirm that a service relationship can be established for your model and serial number.
Does Resell CNC offer financing on used ExOne machines?
Yes. Resell CNC offers flexible financing options to help your business acquire the additive manufacturing equipment it needs. Contact us at (844) 478-8181 to discuss terms.
