2026年のワックス3Dプリンター価格：SLSワックスシステムと射出成形金型の比較
A wax 3D printer for investment casting costs $200,000 to $1M or more. Which band you land in is decided by build chamber and laser configuration, not by brand. The number that matters more is the one you do not see in the quotation: at what annual pattern volume does printing beat cutting a steel die.
This page separates those two numbers. It covers what the three platforms in our wax range actually cost to run, what a wax injection tool costs to make and maintain, and where the crossover sits for a foundry casting somewhere between 50 and 5,000 patterns a year.
What a wax 3D printer costs
Three bands cover almost every industrial SLS wax system sold into foundries today. The bands track chamber size and laser count, because both drive build rate and neither is cheap to add later.
| Band | Price | 造形可能領域 | Configuration | Typical payback |
|---|---|---|---|---|
| Entry level | $200K – $400K | 500 – 800 mm | Single laser | 12 – 18 months |
| 中級 | $400K – $700K | 800 – 1,200 mm | Dual material (sand + wax) | 8 – 14 months |
| Large format | $700K – $1M+ | 1,000 – 1,500 mm | High-throughput, high-power laser | 6 – 12 months |
The machine accounts for roughly 45 to 60 percent of five-year cost of ownership. The rest is powder, gas, energy, labour and the burnout cycle downstream. Quoting the machine alone is how a first project gets approved and a second one does not.
Why wax costs more per kilogram than sand
Both processes run on the same platform family. The consumable is what changes, and the consumable is where the running cost lives.
SLS-grade coated sand prices at roughly $1 to $3 per kilogram. PSB pattern wax runs $4 to $12 per kilogram depending on filler content and grade. At a 30 percent refresh ratio, a build that consumes 36 kg of sand consumes 36 kg of wax at three to four times the unit cost. The gap is not marginal, and it is why a sand cell and a wax cell in the same building have different economics even when the machine capital is identical.
There is an upside. Wax patterns that would otherwise be injection moulded eliminate the steel die entirely, and the die is the expensive part of the conventional route. Our SLS 3Dプリンターのコスト内訳 works through the consumable arithmetic in detail, including a per-build costed example that lands between $413 and $783 for a 24-core batch.
The three wax platforms and what they print
Build volume in wax is not the same as build volume in sand on the same frame. The pattern geometry and the powder bed behave differently, so the usable envelope differs by model.
| モデル | Build volume (mm) | Positioned for |
|---|---|---|
| AFS-500 Wax | 500 × 500 × 500 | Compact SLS wax for foundries starting pattern printing in-house |
| LaserCore-5300 Wax | 800 × 600 × 500 | Mid-scale, high-resolution laser for thin-walled and intricate patterns |
| LaserCore-6000 Wax | 1,200 × 800 × 600 | Largest SLS wax platform, built for high-volume investment casting foundries |
All three run the same PSB wax and the same burnout profile. The choice between them is a floor-space decision as much as a chamber decision — the 6000 needs the headroom and the extraction capacity of a production cell, not a corner of the pattern shop.
Wax printing versus injection tooling: where the crossover sits
A wax injection tool is a machined aluminium or steel die with one or more cavities. It costs somewhere between $8,000 and $40,000 depending on cavity count, finish requirement and whether it needs sliders. It also has a lead time, typically four to ten weeks for a first article.
That is the number to compare against, not the printer price.
The arithmetic that decides it
Take a pattern that runs 200 times a year for three years — 600 parts. A two-cavity injection die at $18,000, amortised over 600 parts, adds $30 to every pattern before a single shot of wax is injected. Add maintenance, storage and the cost of scrapping the die when the design changes.
The same 600 patterns printed across three years carry no tooling cost at all. At a build cost of $15 to $40 per pattern depending on size and nesting, the printed route lands at $9,000 to $24,000 over the same period, and the design can change in week two without touching a die.
Run the same pattern 6,000 times a year and the arithmetic inverts. Injection wins decisively, because the die cost spreads across 18,000 parts and the per-part machine time drops to near zero. Printing cannot match that at volume.
The crossover, stated plainly
Below roughly 500 patterns a year per part number, printing wins on total cost. Between 500 and 2,000 it depends on how many design revisions you expect and how much floor space the injection cell needs. Above 2,000, an injection die is almost always the cheaper route and printing is the wrong tool.
The crossover, with numbers
Five assumptions make the comparison concrete. Printed cost per pattern is $25, which is a build cost of roughly $600 divided across 24 nested patterns. An injection die costs $18,000 once. Injection cost per part is $2 in material, machine time and operator attention. Design revisions, maintenance and storage are excluded on both sides, because they move the answer without changing which way it points.
| Patterns per year | Printed, per year | Injection, per year | Cheaper route |
|---|---|---|---|
| 200 | $5,000 | $18,400 | Printing |
| 500 | $12,500 | $19,000 | Printing |
| 800 | $20,000 | $19,600 | Level — the crossover |
| 2,000 | $50,000 | $22,000 | Injection die |
| 6,000 | $150,000 | $30,000 | Injection die |
Solve it algebraically and the break-even lands at 783 patterns a year: 25V = 18,000 + 2V. That single figure is worth more than any brochure comparison, because it is the only number that changes when your volume forecast changes.
The exception is geometry. A pattern with internal channels, undercuts or a wall thickness that a die cannot fill stays a printing job at any volume, because the alternative is not a die — it is a multi-piece die plus a cores operation plus the labour to assemble it.
What the machine quotation leaves out
Four lines catch first-time wax buyers, and none of them appear on the printer invoice.
- Burnout capacity. Printed wax patterns still go through an autoclave or furnace. If the foundry’s existing burnout cycle is sized for injection-moulded trees, it will be the bottleneck before the printer is.
- Powder handling and reclamation. PSB wax is a specialty consumable. Unsintered powder that is not recovered is money in the bin, and the recovery rig is a separate capital item.
- Labour for depowdering. Wax patterns are fragile before burnout. Depowdering and inspection is a skilled manual step, typically two to three hours per build.
- Pattern inspection. Investment casting tolerances are tight enough that printed patterns need dimensional checks before they go to the tree. That is a metrology cost, not a printing cost.
The same logic applies to the sand side of the business, which is why we wrote a separate breakdown of what a metal system actually costs to own. The pattern is identical: machine, consumable, facility, post-processing.
What to ask before you sign
Five questions separate a supplier who has installed wax cells from one who has only sold them.
- What is the certified pattern tolerance, and over what build volume? A tolerance quoted without a chamber size is not a tolerance.
- What is the burnout profile, and has it been validated on this exact wax? PSB wax behaviour in an autoclave is not generic.
- What is the refresh ratio, and what happens to unrecovered powder? At $4 to $12 per kilogram, a bad answer here costs more than the laser upgrade.
- Who validates the first article? The first build after installation is where most projects lose a month.
- What is the service response time, and is there a technician in the region? A wax cell down during a production run is a foundry down.
When a wax printer is the wrong purchase
Three situations where we tell customers to buy something else.
Three situations where we tell customers to buy something else.
Volume above 2,000 patterns a year on one part number. Cut the die. The maths does not work in printing’s favour and no amount of throughput improvement closes the gap.
A foundry with no burnout capacity and no intention of adding it. The printer will sit idle waiting for a furnace slot. Buy the service instead — our wax 3D printing service exists precisely for this case.
Patterns that are simple extrusions. If the geometry can be turned or milled from a wax billet in an hour, a CNC lathe is cheaper than any printer for that part.
よくある質問
2026年、ワックス3Dプリンターの価格はいくらになるのでしょうか？
エントリーレベルのSLSワックスシステムは、約$200,000からとなっています。 砂とワックスの両方を印刷できる中級クラスのデュアルマテリアルプラットフォームは、$400,000から$700,000の価格帯で、大判・高スループットシステムは$1Mを超えます。 価格帯はチャンバーのサイズとレーザーの構成によって決まり、機械本体は5年間の総所有コストの45～60％を占めます。.
ワックス3Dプリンターは、ワックス射出成形金型よりも安価ですか？
Below roughly 500 patterns a year per part number, yes. A two-cavity injection die at $18,000 amortised over 600 parts adds $30 per pattern before any wax is injected; printing carries no tooling cost at all. Above 2,000 patterns a year the die wins decisively.
1台の機械で、砂とワックスの両方を印刷することはできますか？
Yes. Every AFS and LaserCore platform prints both materials — the switch is a powder change, not a machine change. That is why the mid-range band is described as dual material, and it is the configuration most foundries buy first.
PSBワックスの1キログラムあたりの価格はいくらですか？
PSBパターンワックスの消費量は、充填剤の含有量やグレードに応じて1キログラムあたり$4～$12の範囲ですが、SLSグレードの被覆砂の場合は1キログラムあたり$1～$3です。リフレッシュ比が30％の場合、この差がワックスセルのランニングコストに大きな影響を与えます。.
ワックスモデルの製作にはどれくらい時間がかかりますか？
Between 80 and 200 cm³/h on the AFS-500, 150 to 400 cm³/h on the LaserCore-5300, and 80 to 300 cm³/h on the LaserCore-6000. Real build time also includes heating, cooling and depowdering, so we quote in builds per week rather than cm³/h.
