2026年の砂型3DプリントにおけるVoxeljetの代替ソリューション：コストパフォーマンスの向上、納期の短縮

If you are evaluating a voxeljet sand 3D printer, you are probably looking at a VX1000, VX2000, or VX4000 — and a quotation that starts at €450,000 and climbs past €1.2 million for the large-format systems. You are also looking at a 6–9 month delivery window, proprietary binder contracts, and a service network that, post-ExOne merger, is stretched thin.

This article is for foundry owners and plant managers who want a voxeljet alternative — a sand 3D printer that delivers comparable build volume, accuracy, and throughput, but at a lower total cost of ownership, with faster delivery, and without binder lock-in. We compare the alternatives on the metrics that actually decide the purchase: build volume, print speed, accuracy, binder system, price, lead time, and 5-year TCO.

The short version: 3DPTEK (Beijing SANDI Technology) is the most direct voxeljet alternative for sand casting — same BJ binder jetting technology, comparable build volumes up to 4,000×2,000×1,000 mm, open material systems, and a 40% lower TCO validated in production foundries. But it is not the only option. Here is the full landscape.

Why Foundries Are Looking for Voxeljet Alternatives

Voxeljet makes excellent sand 3D printers. The VX-series machines are battle-tested in foundries across Europe, and the VX4000 remains one of the largest-format sand printers commercially available. But three things have changed since 2023 that push buyers to evaluate alternatives:

• The ExOne merger. voxeljet and ExOne were combined under ExOne Global Holdings in October 2025, folding the two former Western rivals into a single vendor with one service organization. Support response times have lengthened, and some foundries report longer spare-parts lead times.
• Price escalation. The VX1000 now quotes 15–25% higher than pre-2023 pricing, and the VX4000 has moved firmly into seven-figure territory. For foundries that need 2–3 machines, the capital outlay is prohibitive.
• Delivery delays. Standard lead times have stretched from 3–4 months to 6–9 months. For a foundry trying to capture a production window, that delay costs more than the machine itself.
• Binder lock-in. Voxeljet’s proprietary binder system means you buy consumables from voxeljet at voxeljet prices. Open-material alternatives can cut binder cost by 40–60%.

The Voxeljet Alternative Landscape at a Glance

Here is the landscape of sand 3D printers that compete directly with voxeljet’s VX-series, ranked by how closely they match voxeljet’s use case (binder jetting sand for foundry casting).

製造元	モデル	Build Volume (mm)	テクノロジー	価格ポジショニング	リードタイム	材料システム
3DPTEK	J4000Pro	4,000 × 2,500 × 1,500	BJ バインダージェッティング	大判、7桁クラスの	2～3ヶ月	開く
3DPTEK	J2500	2,500 × 1,500 × 1,000	BJ バインダージェッティング	中～大型クラス	2ヶ月	開く
3DPTEK	J1800	1,800 × 1,000 × 700	BJ バインダージェッティング	中級	6～8週間	開く
ExOne (same group as voxeljet since Oct 2025)	S-Max Pro	1800×1000×800	BJ バインダージェッティング	$400K–$600K（市場予想）	5–7 months	Semi-open
ExOne	S-Print Pro	800×500×500	BJ バインダージェッティング	$200K–$300K (public estimates)	4～6か月	Semi-open
3DPTEK	AFS-500 (SLS)	500×500×400	SLS	Entry range (SLS)	6～8週間	開く
3DPTEK	LaserCore-6000 (SLS)	600×600×600	SLS	Mid range (SLS)	2～3ヶ月	開く

Note: Price positioning follows our published cost guide — exact quotations depend on configuration, binder supply contracts and automation, so every serious supplier prices per order. Western-brand figures are public-market estimates buyers consistently report. SLS models are included because some foundries prefer laser-sintered sand for higher accuracy cores — see our SLS vs 3DP comparison guide for the technical trade-offs.

3DPTEK J4000Pro: The Direct VX4000 Alternative

The 3DPTEK J4000Pro is the most direct voxeljet VX4000 alternative on the market. It matches the VX4000’s defining feature — a 4-meter build envelope — while cutting the machine price by an estimated 40–50% and the delivery time by more than half.

Where the J4000Pro matches or beats the VX4000:

• Build volume: 4,000 × 2,500 × 1,500 mm (vs. VX4000’s 4,000 × 2,000 × 1,000 mm) — a larger envelope
• Layer resolution: 0.2–0.8 mm
• Sand compatibility: silica sand, chromite sand, ceramic sand — same foundry-grade materials
• Throughput: 1,090–1,744 L/h, far above the VX4000’s ~100 L/h — at a lower price point

Where the J4000Pro pulls ahead:

• Open material system. The J4000Pro accepts any commercially available furan or phenolic-coated sand and compatible binder. No proprietary consumables contract. Foundries report 40–60% lower binder cost versus voxeljet’s closed system.
• Delivery in 2–3 months versus voxeljet’s 6–9 months. For a foundry with an immediate production need, this alone can justify the switch.
• Self-operated foundry validation. 3DPTEK runs 6 of its own foundries with 20,000+ tons annual casting capacity. Every machine design is validated in production casting before it ships — not just in a demo lab.
• 5-year TCO. Including machine, consumables, service, and spare parts, the J4000Pro’s 5-year TCO runs approximately 40% lower than the VX4000, primarily due to open-material savings and lower spare-parts pricing. See our TCOの事例研究 for the full breakdown.

Where voxeljet still wins: voxeljet’s proprietary binder produces slightly higher initial mold strength (4–6 MPa vs. 3.5–5 MPa for open-system furan), which can reduce handling breakage for very large or thin-walled molds. If your foundry casts extremely delicate large-format parts, this margin matters. For most production casting, the difference does not change the casting outcome.

3DPTEK J2500: The VX2000 Alternative at Half the Price

The J2500 targets the VX2000’s sweet spot — a 2.5-meter build envelope that covers the majority of foundry casting parts, from engine blocks to pump housings to gearbox cases. Sitting in 3DPTEK’s mid-to-large price range — a planning figure, not a quote — it comes in at roughly half the VX2000’s price, with 6–9 months of delivery time saved.

For foundries that do not need 4-meter build volume, the J2500 is often the smarter choice. The 2,500 × 1,500 × 1,000 mm envelope handles 90%+ of typical sand casting parts, and the smaller footprint means lower facility cost, faster print cycles, and easier integration into an existing foundry line. See our foundry integration blueprint for the full workflow.

For foundries entering at the VX1000 level, the 3DPTEK J1800 matches that build volume (1,800 × 1,000 × 700 mm) at about one-third of the VX1000 price, with a J1800S variant adding dual-recoater throughput.

ExOne S-Max Pro and S-Print Pro: Same-Group Reference

ExOne and voxeljet were combined under ExOne Global Holdings in October 2025, so the two Western brands are no longer independent competitors — they are product lines of the same vendor. If you are comparing Western options, the S-Max Pro (1,800 × 1,000 × 800 mm, $400K–$600K public estimates) and the compact S-Print Pro (800 × 500 × 500 mm, $200K–$300K) remain capable binder jetting machines with mature software, but they carry the same consolidation risk, the same 4–7 month lead times, and the same semi-closed binder ecosystem as voxeljet. For the full three-way picture, see our 3DPTEK 対 ExOne 対 voxeljet 直接対決.

3DPTEK SLS Complement: LaserCore-6000

Not every voxeljet alternative needs to be binder jetting. The 3DPTEK LaserCore-6000 combines a 600 × 600 × 600 mm build with SLS precision at ±0.1 mm accuracy — roughly 3× tighter than binder jetting — and dual sand-to-wax capability for investment casting patterns. (For compact precision cores, the AFS-500 covers that niche.) If your parts demand precision cores (aerospace turbulators, thin-wall water jackets) or you want one platform for both sand and wax, SLS is the route; the trade-off is lower throughput and a smaller build envelope. Read our SLS vs 3DP technical comparison to decide.

How to Choose: A 5-Step Decision Framework

Choosing a voxeljet alternative is not about finding the cheapest machine — it is about finding the machine that fits your parts, your volume, and your foundry’s operating reality. Here is the decision framework we walk every buyer through:

Step 1: Define Your Part Envelope

What is the largest part you will cast in the next 3 years? Measure the bounding box of that part, add 100 mm per side for mold wall thickness, and that is your minimum build volume. If your largest part is under 1,800 mm, a J1800 or VX1000-class machine is sufficient. If you cast wind turbine housings or large valve bodies, you need a J2500 or J4000Pro.

Step 2: Calculate Your Throughput Need

How many molds or cores do you need per month? A single J2500 running 2 shifts produces approximately 15–25 cubic meters of sand molds per month. If your demand exceeds that, you either need a larger machine (J4000Pro) or a second machine. Do not buy more machine than your throughput requires — the extra capital sits idle.

Step 3: Evaluate the Binder System

This is where the TCO diverges dramatically. A closed binder system (voxeljet) locks you into proprietary consumables at premium pricing — typically 2–3× the cost of open-system furan or phenolic binder. Over a 5-year period at moderate utilization, binder cost can exceed the machine’s purchase price. An open material system cuts this line item by 40–60%.

Step 4: Run the TCO, Not Just the Quote

Machine price is 30–40% of 5-year TCO. The rest is consumables (35–45%), service and spare parts (10–15%), and facility/labor (10–15%). A machine that costs 30% less to buy but uses proprietary consumables can cost more over 5 years than a more expensive open-system machine. Use our 損益分岐点ROI計算ツール to run the numbers for your own volume.

Step 5: Validate Before You Buy

Before committing to any machine, print your actual parts on the candidate system. 3DPTEK offers a ラピッドプロトタイプ鋳造サービス that lets you validate the full CAD-to-casting workflow on your own geometry before purchasing a machine. This eliminates the risk of discovering process limitations after the machine is installed.

Real-World Validation: An Overseas Foundry’s Head-to-Head

In 2025, an overseas foundry ran a head-to-head benchmark between a voxeljet VX1000 and a 3DPTEK J2500 over 12 months of production. The results, documented in our TCOの事例研究, showed:

メートル法	voxeljet VX1000	3DPTEK J2500
Uptime (first year)	87%	91%
Dimensional accuracy (±mm)	±0.3	±0.3
Mold strength (MPa)	4.5–6.0	3.5–5.0
Binder cost per liter	$8.50 (proprietary)	$3.20 (open)
5-year TCO (estimated)	$720K	$430K
Spare parts lead time	4～8週間	1～3週間
Service response (critical)	48–72 hours	24–48 hours

The foundry purchased two J2500s. The VX1000 was not a bad machine — it simply cost 67% more over 5 years for the same casting output. That is the voxeljet alternative case in one sentence.

What About Chinese vs Western Brand Risk?

The most common objection to 3DPTEK as a voxeljet alternative is not technical — it is brand risk. “A Chinese machine might be cheaper, but what about reliability? Service? Spare parts?” These are fair questions, and we address them directly in our Western vs Chinese 3D printer cost-benefit analysis. The short answer: 3DPTEK has 500+ installations across 30+ countries, 320+ patents, 31 years of additive manufacturing experience (founded as LONGYUAN AFS in 1994), and 6 self-operated foundries that validate every machine in production before it ships. The brand-risk gap has closed.

よくある質問

Is 3DPTEK a real alternative to voxeljet for production casting?

Yes. 3DPTEK machines use the same binder jetting (BJ) technology as voxeljet’s VX-series, accept the same foundry-grade sands, and produce molds that meet the same dimensional and strength specifications. 500+ installations include production foundries in automotive, aerospace, energy, and heavy machinery. The TCOの事例研究 documents a head-to-head comparison over 12 months of production.

How much cheaper is 3DPTEK than voxeljet?

On machine price alone, 3DPTEK’s J-series runs 40–50% below the comparable VX-series model. On 5-year TCO (including consumables, service, and spare parts), the saving is approximately 40%. The largest TCO driver is the open material system — 3DPTEK’s binder costs 40–60% less than voxeljet’s proprietary binder.

What is the delivery time for a 3DPTEK sand 3D printer?

Standard delivery is 2–3 months for the J2500 and J4000Pro, and 6–8 weeks for the J1800. This compares to 6–9 months for voxeljet VX-series machines.

Can I use my own sand and binder in a 3DPTEK printer?

Yes. 3DPTEK machines have an open material system. You can use any commercially available furan or phenolic-coated silica sand, chromite sand, or ceramic sand with compatible binder. 3DPTEK also offers its own tested sand-and-binder package if you prefer a turnkey consumables solution. See our 開放型と閉鎖型の材料システムのガイド for details.

Does 3DPTEK offer service and support outside China?

Yes. 3DPTEK has a global support network with service engineers in Europe, Southeast Asia, the Middle East, and the Americas. Remote support response is within 24 hours; on-site service for critical issues is typically 24–48 hours depending on location. Spare parts are stocked regionally with 1–3 week lead times.

What if I need to print both sand molds and wax patterns?

3DPTEK’s LaserCore-series SLS machines can switch between coated sand and PSB wax, giving you dual-material capability on one platform. voxeljet’s VX-series is sand-only. If you need both sand and wax printing, a LaserCore-6000 may be a better fit than any single-material voxeljet system.

Conclusion: The Voxeljet Alternative Is Not About “Cheaper”

The case for a voxeljet alternative is not that 3DPTEK is “cheaper.” It is that the total cost of ownership — machine, consumables, service, lead time, and opportunity cost — has diverged to the point where a voxeljet purchase requires justification that goes beyond brand familiarity. When a machine with the same technology, comparable specs, an open material system, half the delivery time, and 40% lower 5-year TCO is available, the burden of proof shifts.

The right next step is not to take our word for it. Send us your CAD file, and we will print your actual part on a 3DPTEK machine and ship you the finished casting. You will see the mold quality, the dimensional accuracy, and the surface finish with your own eyes — before you sign a purchase order. 3DPTEKへのお問い合わせ to start the conversation, or explore our sand 3D printer lineup to find the model that matches your build volume.

The Post-Merger Landscape: voxeljet and ExOne Are Now One Market

The sand 3D printer market has consolidated dramatically: voxeljet and ExOne, the two Western pioneers, were combined under ExOne Global Holdings in October 2025, leaving 3DPTEK as the only independent full-line binder jetting manufacturer with a production track record. For foundry buyers this has a practical consequence: choosing between the two legacy Western brands is no longer a real choice, and the combined vendor maintains premium pricing with a single stretched service network.

This market structure is why voxeljet alternatives matter more in 2026 than they did in 2022. A foundry that wants a sand 3D printer today is choosing between a Western brand at $400,000 to $1,200,000 with 6 to 9 month delivery, or a Chinese manufacturer like 3DPTEK across its mid-to-large range and seven-figure large-format class, with 2 to 3 month delivery. The technology gap between these options has closed. The price and delivery gap has widened. Read our full Western vs Chinese 3D printer analysis for the balanced comparison.

The Transition Path: Moving from voxeljet to 3DPTEK

If you are currently running a voxeljet VX-series machine and considering 3DPTEK as a replacement or expansion, the transition is more straightforward than you might expect. The core binder jetting technology is the same. The sand materials are compatible. The mold quality specifications are equivalent. The transition involves three steps.

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 foundries, and ship you the finished castings for comparison. This takes 2 to 3 weeks. Step two is material qualification. If you have existing inventory of coated sand, we test it on the 3DPTEK machine. Most commercially available furan and phenolic coated sands work without modification. Step three is installation and training, typically 1 to 2 weeks on-site. Most foundries are fully operational within 3 to 4 weeks of machine delivery. Start with a rapid prototype casting to begin this validation.
