เครื่องพิมพ์ 3D แบบทราย voxeljet vs ExOne: การเปรียบเทียบโดยตรงสำหรับโรงงานหล่อ (และบทบาทของ 3DPTEK)
Voxeljet and ExOne built the sand 3D printing category for foundries, and the honest head-to-head answer is that neither machine “wins” outright — they win in different budget classes, and a third option now sits directly beneath them. A voxeljet VX1000 (1000 × 600 × 500 mm) carries a published academic purchase record of roughly €750,000 delivered, while an ExOne S-Max Pro (1800 × 1000 × 800 mm) is publicly estimated at roughly 2–3× the price of a 3DPTEK J1800 — a machine with the identical build volume. Both Western vendors typically quote 4–9 months delivery against 6–8 weeks for the J1800. And if you want VX4000-class volume (4000 × 2000 × 1000 mm) without the flagship premium, the 3DPTEK J4000Pro delivers the same chamber in the seven-figure class. This article compares the two pioneers model by model, then shows exactly where 3DPTEK fits.
Two Pioneers, One Process
The two companies that defined binder jetting for castings are voxeljet AG of Friedberg, Germany, founded in 1999, and ExOne, whose roots go back to MIT-licensed binder jetting research and which, like voxeljet, now sits under ExOne Global Holdings after the October 2025 merger. Together they took sand printing out of the research lab. voxeljet proved that a binder jetting machine could hold a job box measured in meters; ExOne proved that a mid-size foundry could run one as a daily production tool rather than a prototype curiosity. Any serious buying conversation about sand 3D printers starts with these two reference points, and any serious competitor — including 3DPTEK — is measured against them.
The context matters as much as the hardware. Both vendors have spent two decades accumulating what actually makes a sand printer usable in a foundry: process documentation for sand and binder combinations, job-preparation software refined against real part geometries, service networks that respond when a printhead misbehaves, and an installed base that feeds field fixes back into the product. That is why BMW’s Landshut light-metal foundry, aerospace primes casting structural brackets, and automotive supply chains feeding the Toyota casting ecosystem run binder jetting systems from this generation of vendors, and why shows such as INTERMOLD in Nagoya are dominated by the same two booths plus their Chinese challengers. The comparison below is not about which brand is “better.” It is about which machine class, price point, and delivery timeline fits a specific foundry.
voxeljet: Large-Format Heritage and the VX4000
voxeljet’s reputation rests on the VX4000, the 4000 × 2000 × 1000 mm binder jetting system that made the company famous. It was the machine that demonstrated sand printing could scale from cores and small molds to chambers measured in meters — the footprint a large jobbing foundry or a heavy-casting supplier needs for engine blocks, gearbox housings, and structural castings. That large-format heritage is a real asset: the VX4000 has been through years of field refinement, and the continuous-printing, printhead, and layer-recording technology voxeljet built around it is mature and thoroughly documented.
Below the flagship, the VX1000 (1000 × 600 × 500 mm) is the model that appears in universities and small-to-mid production environments — and it is the machine whose cost is most visible in public records. A published academic purchase record puts a VX1000 at roughly €750,000 once delivered and installed; treat that as a public estimate, because voxeljet prices every system by configuration. The trade-off is equally well known: voxeljet’s per-build-volume cost is the highest in the category, and delivery from order to production typically runs 4–9 months. For a foundry that needs the proven large-format brand and has the budget and schedule to absorb it, the VX4000 remains a defensible flagship choice. For everyone else, that premium is the opening through which alternatives — including 3DPTEK’s J4000Pro — enter the conversation.
ExOne: Mature Software and a Deep Installed Base
ExOne’s strength is the opposite side of the same coin: less raw scale, more refinement per cubic meter. The S-Max Pro (1800 × 1000 × 800 mm) is the workhorse of the mid-size class, and its reputation is built on software and process maturity. Job preparation, nesting, parameter management, and the general workflow of moving from CAD to a good core or mold are the parts of the system the operator touches every day — and this is where the S-Max Pro’s very large installed base shows. The software has been hardened by thousands of production shops, and its process documentation for furan and phenolic binder systems is the reference material many foundries learn from.
The compact S-Print (1200 × 750 × 500 mm job box) extends the same platform downward for toolrooms, universities, and low-volume producers who want an ExOne without an S-Max Pro footprint. And the fact that ExOne now shares a corporate structure with voxeljet under ExOne Global Holdings brings a question mark along with resources: the brand’s future is tied to a broader AM portfolio, which matters to buyers planning a ten-year roadmap. On price, public estimates consistently place the S-Max Pro at roughly 2–3× what a comparable 3DPTEK J1800 costs — and the two machines share the identical 1,800 × 1,000 × 700 mm build volume. Delivery for the S-Max Pro and S-Print typically runs the same 4–9 months as voxeljet’s.
In production, the S-Max Pro is rarely bought alone. It sits in a workcell alongside a Laempe-class core shooter, sand reclamation, and a binder dosing station — the same cell layout you see in pump and valve foundries and in automotive suppliers, where 3D-printed cores feed conventional core assembly. That installed base is exactly why ExOne’s software remains the benchmark: the workflow has been optimized for foundries that run three shifts and cannot afford a job-preparation bottleneck. When you compare vendors, compare the whole cell, not just the printer — and remember that an open-material system lets you build the same cell with your existing sand supplier and reclamation loop rather than adopting a vendor’s consumable chain.
The Head-to-Head Table
The table below compresses the comparison into the six data points a buyer actually asks for: build volume, price positioning, delivery, and the material system. Western figures are public estimates or published records as noted; 3DPTEK pricing is given as configuration-dependent bands, because we quote per configuration.
| Vendor / Model | ปริมาตรพื้นที่ก่อสร้าง | การกำหนดตำแหน่งราคา | Delivery | ระบบวัสดุ |
|---|---|---|---|---|
| voxeljet VX1000 | 1000 × 600 × 500 มม. | ~€750k delivered (public estimate; academic purchase record) | 4–9 months | Furan, phenolic, inorganic binder systems (vendor binder portfolio) |
| voxeljet VX4000 | 4000 × 2000 × 1000 mm | Flagship premium, well above the VX1000 (quote per project) | 4–9 months | Furan, phenolic, inorganic binder systems (vendor binder portfolio) |
| ExOne S-Max Pro | 1800 × 1000 × 800 มม. | Roughly 2–3× the 3DPTEK J1800 (public estimate) | 4–9 months | Furan and phenolic binders; wide sand compatibility |
| ExOne S-Print | 1200 × 750 × 500 mm (job box) | Compact entry tier, below the S-Max Pro (public estimates scarce) | 4–9 months | Furan and phenolic binders; compact format |
| 3DPTEK J1800 | 1,800 × 1,000 × 700 มม. | ระดับกลาง, ขึ้นอยู่กับความกำหนดค่า | 6–8 สัปดาห์ | Open material system — furan, phenolic, inorganic; any qualified sand |
| 3DPTEK J2500 | 2,500 × 1,500 × 1,000 มม. | ระดับกลางถึงใหญ่, ขึ้นอยู่กับรูปแบบการตั้งค่า | ~2 months | Open material system — furan, phenolic, inorganic; any qualified sand |
| 3DPTEK J4000Pro | 4,000 × 2,500 × 1,500 มม. | ขนาดใหญ่, ระดับเจ็ดหลัก | 2–3 เดือน | Open material system — furan, phenolic, inorganic; any qualified sand |
Two facts in that table deserve emphasis before we move on. First, the ExOne S-Max Pro and the 3DPTEK J1800 are the same build-volume class: 1,800 × 1,000 × 700 mm on both machines. Second, the voxeljet VX4000 and the 3DPTEK J4000Pro share the same chamber: 4,000 × 2,500 × 1,500 mm. The differences are price positioning, delivery, and material-system openness — not the size of the box.
Price Reality: What These Machines Actually Cost
Neither Western vendor publishes list prices, so the pricing column relies on public estimates — and it is worth being explicit about that. The VX1000’s roughly €750,000 delivered figure comes from a published academic purchase record. The S-Max Pro’s 2–3× positioning is a public estimate relative to the J1800, which is mid range and configuration-dependent. The VX4000 sits above the VX1000 by a wide margin and is quoted per project; the S-Print sits below the S-Max Pro. Nobody disputes the shape of the curve: the two Western pioneers price at the top of the market, and the 3DPTEK line — mid range for the J1800, mid-to-large for the J2500, seven-figure class for the J4000Pro — occupies the bands beneath them.
Total cost of ownership changes the picture further. Three pieces of industry cost data are confirmed again and again in real foundry projects. A machined pattern runs €3,000–€15,000 with a 4–8 week lead time — exactly the cost sand printing removes on low-volume and one-off jobs. Sand reclamation on a well-run binder jetting line recovers 95% or more of the sand. And the five-year TCO of a J1800 or J2500 typically lands at roughly half that of the equivalent Western platform once consumables, maintenance, and downtime are counted. For the full cost model — consumables per kilogram, binder loading, labor, and payback math — our sand 3D printing cost guide walks through the numbers line by line.
Part of the price gap is structural, and worth understanding before you negotiate. A 4000 × 2000 × 1000 mm chamber needs a rigid frame, a heavy recoater gantry, and enough printheads to cover the full width in a single pass; that engineering is expensive regardless of who builds it. The difference between the Western flagships and the 3DPTEK J4000Pro is therefore not the size of the box — it is the cost structure behind it: labor, component sourcing, and the overhead a pioneer carries from two decades of R&D and a global service organization. When you compare, ask every vendor for a delivered, installed, and commissioned price with training included, then compare that against five-year cost per cubic meter of packed sand — not against brochure specs.
Where 3DPTEK Fits
3DPTEK is a Chinese manufacturer (Beijing SANDI Technology) whose positioning is the same build-volume classes at a different price point, delivered on a different schedule. The J1800 (1,800 × 1,000 × 700 mm) faces the S-Max Pro directly. The J2500 (2,500 × 1,500 × 1,000 mm) fills the gap between the Western mid-size and flagship classes. The J4000Pro (4,000 × 2,500 × 1,500 mm) matches the VX4000’s chamber exactly. The material system is open — furan, phenolic, and inorganic binders with any qualified sand you already use — a meaningful difference from vendor-locked consumable chains. Delivery runs 6–8 weeks for the J1800, about 2 months for the J2500, and 2–3 months for the J4000Pro including sea freight, customs, and installation — against the 4–9 months typical of both Western vendors.
Open materials are not a marketing phrase — they change how the machine runs in your foundry. With a 3DPTEK J-series system you keep buying silica, chromite, or ceramic sand from the suppliers you already have contracts with, run furan, phenolic, or inorganic binder systems from the distributors you already trust, and feed the printer from your existing sand preparation and reclamation loop. That keeps consumable costs visible and competitive over the machine’s life, instead of locking you into one vendor’s binder price list. It is the operational difference between buying a printer and buying a printing system with an open consumable market around it.
The honest part of the fit: voxeljet and ExOne have decades of process documentation, mature software, and service networks that a young company cannot claim to have replicated overnight. A foundry whose risk model demands the largest installed base of reference installations, or whose customers require a Western brand on the floor, should buy the pioneer. 3DPTEK’s edge is concrete and quantifiable: the same class of build volume at mid-range pricing, open materials, and a production timeline measured in weeks rather than months. Our head-to-head comparison of 3DPTEK vs ExOne vs voxeljet, the profile of seven voxeljet alternatives, and the rundown of five ExOne alternatives lay out the full picture; if you want the structural difference explained in one place, the Western vs Chinese 3D printer article covers it.
The Decision Rule
Distilled to a rule, the choice looks like this:
- You need the proven large-format flagship with the deepest process history — the VX4000 remains the reference buy, if the budget and the 4–9 month schedule work.
- You need S-Max Pro-class volume (1800 × 1000 × 800 mm) and value the most mature software in the category — the S-Max Pro is the safe choice; budget for roughly 2–3× the J1800.
- You need VX4000-class volume (4000 × 2000 × 1000 mm) without the flagship premium — the J4000Pro delivers the same chamber in the seven-figure class.
- You are a mid-size foundry that wants 1800 × 1000 × 800 mm capacity, open materials, and 6–8 week delivery — the J1800, mid range and configuration-dependent.
- You need a middle volume between the Western classes — the J2500 (2,500 × 1,500 × 1,000 mm).

คำถามที่มักถูกถาม
Which is better: voxeljet or ExOne?
Neither is objectively better — they are the two reference vendors of the category, and each wins a different argument. voxeljet is the large-format heritage brand: the VX4000’s 4000 × 2000 × 1000 mm chamber is the class benchmark, and the smaller VX1000 is well documented in academic and industrial use. ExOne counters with the S-Max Pro’s mature software, its job-preparation workflow, and a deep installed base among mid-size foundries. If the question is which machine fits a specific foundry, the deciding factors are build-volume class, delivered price, and time to production — not brand.
How much does a voxeljet sand 3D printer cost?
Public figures are scarce because voxeljet prices by configuration, but one published academic purchase record puts the VX1000 at roughly €750,000 once delivered and installed — treat that as a public estimate, not a list price. The VX4000 is the flagship and costs well above that; voxeljet quotes it per project. On top of the machine, budget for binders, sand handling, installation, and training. For the same work volume at a mid-range price band, a 3DPTEK J1800 or J2500 is the usual alternative — our head-to-head comparison of 3DPTEK vs ExOne vs voxeljet walks through the trade-offs.
How much does an ExOne sand 3D printer cost?
ExOne does not publish list prices for the S-Max Pro, but public estimates consistently place it at roughly 2–3× the price of a comparable 3DPTEK J1800 — and the two machines share the same 1,800 × 1,000 × 700 mm build volume. The compact S-Print sits below that, and like all vendors ExOne prices by configuration, binder system, and accessories. Five-year TCO is the more meaningful number: for the J1800 and J2500 classes it typically runs about half that of the equivalent Western platform once consumables, maintenance, and downtime are included.
Is the voxeljet VX4000 still the largest?
The VX4000’s 4000 × 2000 × 1000 mm chamber made it the famous large-format benchmark in binder jetting, and it remains one of the biggest production sand printing systems in regular use. But “largest” is no longer exclusive: the 3DPTEK J4000Pro offers the same 4,000 × 2,500 × 1,500 mm build volume in the seven-figure class, and several Chinese and European builders now ship comparable chambers. So the VX4000 still defines the format’s heritage, but it is no longer the only way to get that footprint — or the least expensive one.
Which has better software: voxeljet or ExOne?
ExOne’s S-Max Pro is generally credited with the more mature out-of-the-box software: its job preparation, nesting, and process-parameter workflow has been refined across a very large installed base, which is a genuine strength. voxeljet’s software is solid and well documented, and both vendors have decades of process documentation behind them. The honest answer for a buyer is to trial the job-preparation workflow on your own parts before deciding, because software feel matters more than feature lists. Open-material systems such as 3DPTEK’s let you keep your existing workflow while switching hardware.
How does 3DPTEK compare with both?
3DPTEK competes by matching the same build-volume classes at a different price point: the J1800 (1,800 × 1,000 × 700 mm) sits in the S-Max Pro’s class, and the J4000Pro (4,000 × 2,500 × 1,500 mm) matches the VX4000. The J1800 is mid range and configuration-dependent, delivery is 6–8 weeks against the Western 4–9 months, and the material system is open — furan, phenolic, and inorganic binders with your choice of qualified sand. The trade-off is honest: voxeljet and ExOne have decades of process documentation, mature software, and global service networks; 3DPTEK wins on price, delivery speed, and openness.
