Understanding how custom 3D printing services calculate pricing helps you budget accurately, make informed decisions about material and quality options, and recognize fair value when comparing quotes across providers. Whether you are commissioning a single custom figurine or planning a production run of hundreds of decorative pieces, the pricing structure follows consistent principles rooted in material usage, machine time, and production complexity.
3DCentral is developing an on-demand custom 3D printing service at our Laval, Quebec facility, designed specifically for decorative objects, figurines, cosplay props, and collectibles. While we prepare for launch, understanding the pricing model gives prospective customers a clear picture of how their project costs will be calculated and what levers they can pull to optimize their budget.
The Foundation: Volume-Based Pricing
The core of virtually every 3D printing quote is volume-based pricing. The cost starts with the physical volume of material your object requires, measured in cubic centimeters. This approach is fundamentally fair because you pay for exactly what you use. A small figurine occupying 50 cubic centimeters of material costs proportionally less than a large bust at 500 cubic centimeters.
Volume-based pricing differs from the size-based pricing that some services use, and the distinction matters for cost-conscious customers. Two objects with identical outer dimensions can have vastly different volumes depending on their geometry. A solid cube uses much more material than a hollow sphere of the same height and width. Volume-based pricing means you are not penalized for choosing designs with efficient geometry, and you are not subsidizing other customers whose objects use more material than yours.
The volume calculation is performed automatically from the 3D model file. When you upload an STL, OBJ, or 3MF file, the quoting system analyzes the mesh geometry to determine the enclosed volume. This calculation takes microseconds and produces a precise number that serves as the base multiplier for the entire quote.
At 3DCentral, the base rate per cubic centimeter varies by material. Standard PLA occupies the lowest tier, reflecting its lower raw material cost and established printing parameters. Specialty materials carry higher per-centimeter rates that account for both material cost and the additional printer calibration and monitoring required.
Material Multipliers: How Material Choice Affects Cost
Material selection is the first major variable in a custom 3D printing quote, and it impacts cost through several mechanisms beyond simple raw material price.
PLA: The Cost-Effective Standard
PLA (polylactic acid) is the most affordable option for custom prints. It produces excellent surface detail, prints reliably at moderate temperatures, and works well for the vast majority of decorative objects and display figurines. The material cost per kilogram is the lowest among common printing filaments, and the established printing parameters mean less machine time is spent on calibration and failed prints.
For indoor display pieces, desk figurines, shelf collectibles, and protected decorative objects, PLA delivers the best value per dollar spent. The surface quality rivals more expensive materials, and the color range available in PLA is broader than any other filament type.
PETG: Durability at a Premium
PETG costs more than PLA both in raw material price and printing complexity. The higher printing temperatures require more energy, and PETG’s tendency toward stringing means prints often require more post-processing cleanup. These factors contribute to a material multiplier typically 20-40% above PLA pricing.
The premium is justified for any application involving outdoor exposure, frequent handling, or functional stress. PETG’s UV resistance, moisture resistance, and impact strength significantly exceed PLA. For garden figurines, outdoor decorative pieces, items that will be handled regularly, or anything destined for a non-climate-controlled environment, PETG is the recommended choice despite the higher cost.
Specialty Filaments
Silk PLA, metallic PLA, glow-in-the-dark, and other specialty filaments carry premium multipliers reflecting their higher raw material costs and the additional printing challenges they present. Silk filaments require careful temperature management to maintain their luster. Glow-in-the-dark filaments are abrasive to printer nozzles, increasing maintenance costs. Multi-color filaments require precise calibration to achieve consistent color transitions.
These premiums are not arbitrary markups. They reflect real cost differences in materials and production overhead. When a specialty filament produces an effect that standard materials cannot achieve, the premium represents the value of that unique aesthetic.
Infill Percentage: The Internal Structure Variable
Infill percentage determines how much material fills the interior of a printed object. At 0% infill, the object would be completely hollow with only outer walls (though no service prints at 0% for structural reasons). At 100% infill, the object is completely solid plastic throughout.
Most decorative figurines print effectively at 10-20% infill. This range provides adequate structural strength for display pieces while using significantly less material and print time than higher percentages. The internal structure at these infill levels consists of a geometric pattern (typically gyroid or grid) that distributes stress evenly through the object.
Higher infill percentages are appropriate for specific use cases. A figurine that will be handled frequently benefits from 30-40% infill for impact resistance. A piece designed as a paperweight or that needs significant heft for stability might warrant 50-80% infill. Fully solid prints at 100% infill are rarely necessary for decorative objects and should only be selected when the application specifically demands maximum density.
The cost impact of infill is linear with material usage. Doubling the infill percentage roughly doubles the material consumed and proportionally increases print time. Moving from 15% to 30% infill approximately doubles the base volume cost. This means infill selection is one of the most effective cost optimization levers available to customers who want to manage their project budget.
Layer Height: Quality Versus Speed
Layer height determines the vertical resolution of the print. Finer layers produce smoother surfaces but require proportionally more time to complete. A standard layer height of 0.20mm satisfies the vast majority of decorative applications, balancing surface quality with production efficiency.
Fine layer heights of 0.12mm are appropriate for pieces with subtle facial details or small-scale features where the layer stepping of coarser settings becomes visible. The time increase is substantial: a print at 0.12mm takes approximately 67% longer than at 0.20mm, with costs reflecting the additional machine time. Ultra-fine settings below 0.12mm are rarely justified for decorative objects.
Rush Orders and Turnaround Time
Standard turnaround for custom 3D printing at 3DCentral will be 3-7 business days from order confirmation. This window accounts for print queue scheduling, actual printing time, quality inspection, and shipping preparation. Most single-figurine orders complete within the faster end of this range, while larger or more complex orders may require the full window.
Rush orders with 24-48 hour turnaround carry a 1.5x surcharge on the base quote. This premium reflects the real cost of priority scheduling. Rush orders displace other items in the print queue, may require overnight production, and reduce the scheduling flexibility that keeps standard pricing efficient. The surcharge is not a penalty for urgency but a reflection of the operational cost of accommodation.
For time-sensitive projects, consider whether the urgency is genuine. If a gift can be ordered a week earlier, standard turnaround saves 50% of the rush premium. Planning ahead is the single most effective cost-reduction strategy for custom printing projects.
Quantity Discounts: Scaling Cost Efficiency
One of the most compelling aspects of 3D printing economics is the favorable scaling of per-unit costs at moderate volumes. Unlike injection molding, which requires expensive tooling before the first unit can be produced, 3D printing has zero tooling cost. The first unit and the hundredth unit use the same digital file on the same equipment.
At 3DCentral, quantity discounts follow a tiered structure. Orders of 10 or more units receive a 10% discount on the per-unit price. Orders of 25 or more units receive 15% off. Orders of 100 or more units receive 20% off. These discounts reflect genuine production efficiencies: batch printing reduces setup time per unit, material purchasing at volume reduces material cost, and quality inspection becomes more efficient with consistent geometry.
These quantity breaks make 3D printing competitive with traditional manufacturing at volumes that injection molding considers impossibly small. A run of 50 custom figurines is unviable with conventional manufacturing, which requires minimum orders of thousands to amortize tooling. With 3D printing, 50 units is a straightforward production run with meaningful volume pricing.
This scaling advantage benefits small businesses, event organizers, and print farm operators producing custom promotional figurines, wedding favors, or limited-edition collectibles. Print farm operators should also explore the Commercial License for access to our curated STL library.
Getting an Accurate Quote
The most accurate way to understand your project cost is to submit the actual 3D model file for automated quoting. Verbal descriptions and reference photos cannot reliably predict the volume and geometry that determine price. Ensure your model is manifold (watertight) with no holes or inverted normals before submission. Accepted formats at 3DCentral will include STL, OBJ, and 3MF, with a maximum file size of 200MB and automatic geometry validation.

Frequently Asked Questions
Q: What is the minimum order cost for custom 3D printing at 3DCentral? A: The minimum order will be $9.99 CAD. This floor ensures that every order covers the fixed costs of file processing, quality inspection, and shipping preparation regardless of the object’s size. Most figurines and decorative objects naturally exceed this minimum based on their volume and material requirements.
Q: Can I get a quote without uploading a 3D model file? A: Accurate quoting requires a 3D model file (STL, OBJ, or 3MF) because the price depends on the exact volume, geometry, and dimensions of the object. We cannot provide reliable estimates from photos or verbal descriptions alone. If you have a concept but no 3D model, many freelance 3D modelers can create a printable file from your specifications.
Q: How does 3D printing cost compare to injection molding for small runs? A: For quantities under 500 units, 3D printing is almost always more cost-effective than injection molding. Injection molding requires mold tooling that typically costs thousands to tens of thousands of dollars before the first unit is produced. 3D printing has zero tooling cost, making it ideal for short runs, prototypes, and limited-edition collectibles. At very high volumes above several thousand units, injection molding’s per-unit cost advantage eventually offsets the tooling investment.
