3D Print on Demand: Get Custom Parts Without Owning a Printer
3D print on demand has revolutionized how individuals and businesses get custom parts manufactured. Instead of buying expensive equipment or maintaining inventory, you can order exactly what you need, when you need it - whether that's a single prototype or a hundred custom components. This model democratizes access to manufacturing capabilities that were once reserved for large companies.
This guide explains how 3D print on demand works, when it makes sense to use these services, and how to get the best results from your on-demand printing orders.
What is 3D Print on Demand?
3D print on demand means having parts manufactured only when you need them, without maintaining inventory or owning equipment. You submit a design, the service prints it, and ships it to you - often within days.
How It Works
Submit your 3D model file (STL, 3MF, or OBJ) to the service.
Choose material, quantity, finish, and delivery speed.
Get instant pricing based on material volume and options.
Your part is printed, post-processed, and shipped directly to you.
Benefits of 3D Print on Demand
No Equipment Investment
Access industrial-grade printing without buying machines. Entry-level printers start at $200, but professional equipment costs $5,000-100,000+.
No Inventory Risk
Order exactly what you need. No warehouse costs, no obsolete stock, no minimum order quantities (usually).
Access to Multiple Technologies
Use FDM, resin, SLS, MJF, or metal printing depending on your needs - all from one service relationship.
Scalable Production
Need 1 part or 1,000? On-demand services scale with your needs without workflow changes.
Geographic Flexibility
Ship parts anywhere. Some services have global production networks for faster local delivery.
No Learning Curve
Skip the months of learning to operate and tune a 3D printer. Upload and order.
Types of 3D Print on Demand Services
Industrial On-Demand Services
Professional services with engineering-grade equipment. Best for functional parts, production runs, and projects requiring specific material certifications.
Maker Marketplace Services
Connect directly with individual makers and small print farms. More personal service, competitive pricing, and often faster for smaller jobs.
- + Competitive bidding lowers costs
- + Direct communication with maker
- + Local pickup often available
- + Flexible on custom requests
- - Custom one-off projects
- - Hobby and personal items
- - Miniatures and collectibles
- - Small business prototypes
Specialized On-Demand Services
Niche services focusing on specific applications or technologies.
Castable wax, precious metals, fine detail resin
Biocompatible materials, surgical guides, orthotics
Large-scale models, presentation pieces
Materials Available Through On-Demand Services
On-demand services offer far more material options than most individuals could maintain in a home setup:
| Material | Technology | Use Cases | Price Range |
|---|---|---|---|
| PLA / PETG | FDM | Prototypes, models, hobby | $ |
| Standard Resin | SLA/MSLA | Detail parts, miniatures | $-$$ |
| Nylon (PA12) | SLS/MJF | Functional parts, hinges | $$ |
| TPU / Flexible | FDM/SLS | Gaskets, grips, wearables | $$ |
| Stainless Steel | DMLS/Binder Jet | Tools, hardware, jewelry | $$$ |
| Titanium | DMLS | Aerospace, medical implants | $$$$ |
| Full Color Sandstone | Binder Jet | Figurines, architecture models | $$-$$$ |
Understanding On-Demand Pricing
Most on-demand services price based on material volume, with adjustments for complexity and finishing. Here's what to expect:
Typical Pricing Factors
Most services charge per cubic centimeter (cm³) of material. A 50mm cube uses 125 cm³.
Base price x material factor. Nylon might be 2x PLA, titanium might be 20x.
Many services have $15-50 minimums per order regardless of part size.
Post-processing like dyeing, polishing, or painting adds $5-50+ per part.

Best Use Cases for 3D Print on Demand
Product Prototyping
Test form, fit, and function before committing to tooling. Iterate quickly at fraction of injection mold costs.
Replacement Parts
Discontinued or custom parts for equipment, vehicles, appliances. Faster than waiting for overseas shipping.
Custom Gifts & Decor
Personalized items impossible to find in stores. Name plates, custom figurines, unique home accessories.
Small Business Products
Test market demand without inventory investment. Scale production as orders grow.
Cosplay & Props
Custom costume pieces and replicas. Complex shapes not possible with traditional crafting.
Educational Projects
Classroom models, science fair projects, architectural studies. Make abstract concepts tangible.
Typical Turnaround Times
| Service Type | Standard | Rush | Notes |
|---|---|---|---|
| Industrial (Shapeways, etc.) | 5-10 business days | 2-3 business days | Rush fees typically 50-100% extra |
| Maker Marketplace | 3-7 days | 1-2 days | Varies by maker availability |
| Local Print Shop | 1-3 days | Same day | Best for urgent needs |
| Metal Printing | 10-15 business days | 5-7 business days | Complex post-processing required |
Pro tip: Add shipping time to production estimates. Ground shipping adds 3-7 days. Express shipping available but adds $10-50+ depending on size.
Tips for Successful On-Demand Orders
Design for the Technology
Each printing method has different requirements. FDM needs support considerations, resin has minimum feature sizes, SLS allows trapped volumes.
Start with a Prototype
Before ordering quantities, get a single test part. Verify fit, finish, and functionality before committing.
Specify Critical Dimensions
3D prints shrink slightly and have tolerances. Call out dimensions that must be precise for fitting or assembly.
Consider Post-Processing Needs
Will you paint it? Need it smooth? Some finishes require specific base materials or printing orientations.
Communicate Clearly
Explain what the part is for. A decorative item has different requirements than a structural component.
Compare Multiple Quotes
Prices vary significantly between services. A project quoted at $100 somewhere might be $50 elsewhere.
Get Your Parts Printed on Demand
3D print on demand puts manufacturing power in your hands without the overhead of equipment, space, or expertise. Whether you need a single prototype or a hundred custom parts, there's an on-demand solution that fits.
