If you’re using 3D printing for stainless steel parts—whether for industrial components, Luft- und Raumfahrtteile, or custom accessories—understanding the cost per gram is critical for budgeting. Unlike resin or PLA 3D printing, 3D printing stainless steel is far more expensive, with costs ranging from 60 RMB/gram for mass-produced parts Zu 400 RMB/gram for small-batch, Hochvorbereitete Komponenten. In diesem Leitfaden werden die wichtigsten Kostentreiber aufgeschlüsselt, bietet praktische Preishinweise, gibt Tipps zum Kostensparen, und beantwortet häufig gestellte Fragen, um Ihnen dabei zu helfen, fundierte Entscheidungen zu treffen.
1. 4 Kernfaktoren, die sich auf die Kosten pro Gramm 3D-Druck-Edelstahl auswirken
The cost per gram of 3D printed stainless steel is shaped by tangible factors—from the printing technology used to the complexity of post-processing. Below is a detailed breakdown with real numbers to illustrate their impact:
(1) 3D Drucktechnologietyp
Technology is the biggest cost driver, as different methods vary drastically in precision, Geschwindigkeit, and equipment costs. The three most common technologies for stainless steel 3D printing are:
| Technologieart | Kosten pro Gramm (RMB/Gramm) | Schlüsselmerkmale | Typische Anwendungen |
| Selektives Laserschmelzen (Slm) | 130 ~ 400 | Ultrahohe Präzision (Toleranz ± 0,02 mm), suitable for complex structures; high equipment and material costs | Small-batch high-precision parts (Z.B., Medizinische Implantate, Luft- und Raumfahrtkomponenten) |
| Electron Beam Fusion (EBM) | 80 ~ 250 | Ideal for large-scale industrial parts; lower cost than SLM but slightly lower precision (Toleranz ± 0,05 mm) | Mass-produced industrial components (Z.B., robotic arm joints, Ventilkörper) |
| Binding Jetting | 60 ~ 200 | Lowest unit cost for mass production; but requires complex post-processing (Z.B., Debidierung, Sintern) | Bulk-produced small parts (Z.B., custom fasteners, decorative accessories) |
Beispiel: A 50g stainless steel part printed via SLM costs 6,500 ~ 20,000 RMB. The same part printed via Binding Jetting costs 3,000 ~ 10,000 RMB—50% cheaper—though it needs extra post-processing.
(2) Edelstahlqualität
The grade of stainless steel directly affects material costs, as specialized grades (Z.B., korrosionsbeständig, hochfest) are more expensive to produce:
| Edelstahlqualität | Kosten pro Gramm (Nur Material, RMB/Gramm) | Schlüsseleigenschaften | Typische Anwendungen |
| 304 Edelstahl | 10 ~ 30 | Gute Korrosionsbeständigkeit, geringe Stärke; most affordable grade | Nichtkritische Industrie-Teile (Z.B., Einfache Klammern, Dekorative Teile) |
| 316L Edelstahl | 20 ~ 50 | Hohe Korrosionsbeständigkeit (Geeignet für harte Umgebungen), better ductility | Meeresteile, Komponenten chemischer Geräte, medizinische Werkzeuge |
| 17-4PH Edelstahl | 30 ~ 100 | Martensitic steel with high strength and hardness; hitzebehandelbar | Hochbelastete Teile (Z.B., Flugzeugverschluss, Druckbehälterkomponenten) |
Schlüsselnotiz: Imported stainless steel powders (Z.B., from EOS or Carpenter) kosten 2 ~ 3x more than domestic powders (Z.B., from Baosteel or TISCO). Zum Beispiel, imported 316L powder costs 40 ~ 50 RMB/Gramm, while domestic 316L powder costs 20 ~ 30 RMB/Gramm.
(3) Nachbearbeitungsanforderungen
Nearly all 3D printed stainless steel parts need post-processing to meet strength, Genauigkeit, and appearance standards. Each step adds significantly to the total cost per gram:
| Nachbearbeitungsschritt | Kosten pro Gramm (RMB/Gramm) | Zweck |
| Basic Polishing/Sanding | 10 ~ 50 | Remove surface roughness (Ra from 3.2μm to 1.6μm); eliminate layer lines |
| Hochvorbereitete Bearbeitung (CNC Trimming) | 50 ~ 150 | Toleranzen erreichen (± 0,01 mm); refine critical features (Z.B., Löcher, Themen) |
| Electroplating/Coating | 30 ~ 200 | Korrosionsbeständigkeit hinzufügen (Z.B., Chrombeschichtung) or aesthetic finish (Z.B., matte black); aerospace-grade coatings cost the most |
| Wärmebehandlung | 20 ~ 80 | Improve strength and hardness (Z.B., annealing for 17-4PH steel); reduce internal stress |
Beispiel: A 100g part needing basic polishing costs 1,000 ~ 5,000 RMB in post-processing. The same part needing high-precision CNC trimming + electroplating costs 8,000 ~ 35,000 RMB—7x more.
(4) Bestellvolumen
Order volume has a huge impact on cost, als Fixkosten (Z.B., Geräteaufbau, Programmierung) sind auf mehrere Teile verteilt. Small batches are exponentially more expensive than large-scale production:
| Bestellvolumen | Kosten pro Gramm (Gesamt, RMB/Gramm) | Rabatt vs. Einzelstück | Beispiel: 50g 316L Part (SLM -Technologie) |
| Single Piece/Small Batch (<10 Stücke) | 250 ~ 400 | 0% (Kein Rabatt) | 50g × 300 RMB/gram = 15,000 RMB |
| Mittlere Charge (10 ~ 100 Stücke) | 150 ~ 250 | 20 ~ 40% | 50g × 200 RMB/gram = 10,000 RMB |
| Große Charge (>100 Stücke) | 60 ~ 150 | 40 ~ 70% | 50g × 100 RMB/gram = 5,000 RMB |
Beispiel: A single 50g robotic arm joint (Slm, 316L steel) Kosten 15,000 RMB. Bestellung 100 of the same joints drops the cost to 5,000 RMB each—67% cheaper.
2. Typische Kosten pro Gramm: Szenariobasierte Aufschlüsselung
To see how all these factors come together, below are three common scenarios for 3D printing stainless steel parts:
| Szenario | Technologie | Edelstahlqualität | Nachbearbeitung | Kosten pro Gramm (RMB/Gramm) | Beispiel (10g Part Total Cost) |
| Small-Batch High-Precision Part | Slm | 17-4PH | CNC Trimming + Wärmebehandlung | 250 ~ 400 | 2,500 ~ 4,000 RMB |
| Medium-Batch Industrial Part | EBM | 316L | Basic Polishing + Wärmebehandlung | 100 ~ 200 | 1,000 ~ 2,000 RMB |
| Large-Batch Mass-Produced Part | Binding Jetting | 304 | Schleifen + Elektroplierend | 60 ~ 120 | 600 ~ 1,200 RMB |

4. 4 Praktische Tipps zur Reduzierung der Kosten pro Gramm beim 3D-Druck von Edelstahl
While 3D printing stainless steel is inherently expensive, these strategies can help lower costs without sacrificing quality:
(1) Optimieren Sie das Teiledesign, um den Materialverbrauch zu senken
- Geometrie vereinfachen: Remove redundant features (Z.B., unnecessary curves, thick walls) to reduce the part’s weight by 15 ~ 30%. Zum Beispiel, a 50g part optimized to 35g saves 15g of material—cutting costs by 30%.
- Use hollow structures: Für nicht tragende Teile (Z.B., Dekorative Komponenten), design hollow interiors with thin walls (≥1mm) to reduce material consumption by 20 ~ 40%.
(2) Wählen Sie inländische Edelstahlpulver
Inländische Pulver (Z.B., from Baosteel, TISCO) Sind 50 ~ 60% cheaper than imported powders (Z.B., EOS, Tischler) and meet most industrial standards. Zum Beispiel, using domestic 316L powder (20 ~ 30 RMB/Gramm) statt importiert (40 ~ 50 RMB/Gramm) halbiert die Materialkosten.
(3) Sammelbestellungen, um Rabatte freizuschalten
Even small increases in order volume can lead to significant savings. Wenn Sie brauchen 50 Teile vorbei 6 Monate, alles bestellen 50 sofort statt 10 per month—this can unlock a 20 ~ 30% Rabatt, Reduzierung der Kosten pro Gramm um 20 ~ 30%.
(4) Vereinfachen Sie die Nachbearbeitung, wenn möglich
- Überspringen Sie unnötige Schritte: If the part doesn’t need high precision (Z.B., a decorative keychain), Vermeiden Sie CNC-Beschnitt und verwenden Sie stattdessen einfaches Schleifen – das spart Geld 50 ~ 150 RMB/Gramm.
- Combine post-processing steps: Zum Beispiel, handle heat treatment and sanding in one facility to avoid shipping costs and reduce overall fees by 10 ~ 15%.

FAQ
- Why is 3D printing stainless steel so much more expensive than resin or PLA 3D printing?
3D printing stainless steel requires high-cost equipment (SLM/EBM machines cost 1 ~ 10 million RMB vs. 10 ~ 30,000 RMB for resin printers) and specialized metal powders (10 ~ 100 RMB/gram vs. 0.02 ~ 0.2 RMB/gram for resin). Zusätzlich, Nachbearbeitung (Z.B., CNC-Beschnitt, Wärmebehandlung) is far more complex and costly for stainless steel parts.
- Can I use 3D printing stainless steel for small decorative parts (Z.B., Schlüsselanhänger) ohne zu über Ausgaben?
Yes—use Binding Jetting technology with 304 stainless steel powder and basic sanding (no electroplating). A 10g keychain made this way costs 600 ~ 1,000 RMB, which is affordable for small-batch custom orders. Avoid SLM or high-grade powders (Z.B., 17-4PH) für dekorative Teile, as they will double or triple the cost.
- Wie hoch sind die Gesamtkosten pro Gramm 3D-gedruckter Edelstahl durch die Nachbearbeitung??
Die Nachbearbeitung fügt normalerweise hinzu 10 ~ 350 RMB/Gramm, abhängig von den Schritten. Grundschleifen fügt hinzu 10 ~ 50 RMB/Gramm, beim hochpräzisen CNC-Beschneiden + Galvanik fügt hinzu 80 ~ 350 RMB/Gramm. Für die meisten industriellen Teile, Nachbearbeitung berücksichtigt 20 ~ 50% der Gesamtkosten pro Gramm.
