Understanding 3D Printing Costs: Transparency for Your Project
Calculating the cost of a 3D printing project can seem complex at first glance. From simple plastic components to high-precision resin models, several variables influence the final price. In this guide, we explain in detail how we calculate costs at Choanaevo in Vienna, allowing you to plan your budget with precision.
A common misconception is that only the raw printing time determines the price. In reality, the total sum is composed of material consumption, machine run-time, the labor required for preparation, and the chosen technology. In a city like Vienna, where there is high demand for both industrial prototypes and creative design objects, we adapt our calculations to the specific requirements of our clients.
1. Material Costs and Technology
The material used is the first primary cost factor. We distinguish between different processes, each with its own pricing structure. In FDM printing (Fused Deposition Modeling), the price is often calculated per gram of material. Standard materials such as PLA or PETG are more cost-effective, while technical plastics like ABS or ASA are more expensive due to their thermal resistance and higher raw material costs.
In SLA printing (Stereolithography), billing is usually based on milliliters of resin. Since high-precision resins offer significantly higher detail accuracy and mechanical strength than standard resins, this is reflected in the pricing. The choice of material depends directly on the intended use: a pure design draft requires less expensive materials than a functional prototype for an industrial application.
2. Geometry and Material Consumption
The complexity of your model heavily influences material consumption. A solid part consumes significantly more plastic than a hollow part with an optimized infill structure. We often recommend an infill rate of 15-20% for visual models, while functional parts may require up to 100% filling for maximum strength.
Another factor is the support structures. Since 3D printers cannot print parts in mid-air, overhangs must be supported. This additional material is printed but removed after completion. The more complex the geometry and the more overhangs present, the more support material is needed, which slightly increases the total cost.
3. Preparation and 3D Modeling
Before the printer starts, the file must be optimized. The process known as "slicing" is where the 3D model is divided into individual layers. If the provided file is not printable (e.g., gaps in the mesh structure), manual correction is necessary. If you do not yet have a finished file, we offer professional 3D Modeling, which is billed based on actual time spent in hours.
Precise modeling saves money in the long run by avoiding errors during the printing process. We check every model for printability to prevent material waste from failed prints. For detailed information on optimization, visit our guide How to Prepare Your Model for Printing.
4. Time Effort and Machine Usage
Printing time is a function of layer height. A low layer height (e.g., 0.1 mm) ensures an extremely smooth surface but significantly extends the printing time. A coarser resolution (e.g., 0.3 mm) accelerates the process and lowers the cost, though it is less suitable for visually demanding parts.
Additionally, the number of parts printed simultaneously plays a role. If we can place a small series on one print bed, we optimize the machine setup time, which reduces the cost per individual piece compared to a single prototype.
5. Post-Processing and Finishing
The raw print coming out of the machine is rarely the final product. Depending on the requirements, post-processing costs may apply. This includes removing support structures, sanding surfaces, or priming and painting. In our Vienna workshop, we offer professional painting that transforms a prototype into a market-ready product. This process is very time-intensive and is therefore calculated per working hour.
| Factor | Influence on Price | Optimization Potential |
|---|---|---|
| Material Choice | High (per g/ml) | Choosing standard over specialty materials |
| Infill Rate | Medium | Reducing wall thickness and filling |
| Resolution | Medium (Time) | Higher layer height for functional parts |
| Geometry | Low to Medium | Avoiding extreme overhangs |
| Post-Processing | Variable (Time) | Skipping painting for internal prototypes |
6. Local Specifics and Business Terms in Vienna
As a local provider in Vienna, we value transparency and short communication channels. Our prices include the statutory VAT of 20%. For commercial clients (B2B), we offer a payment term of 14 days. We have set a minimum order value of 25 € to cover the administrative costs of order processing.
Especially for start-ups and engineering firms in Vienna, speed is crucial. We offer an express option where prioritization in the queue is available for a 50% surcharge. The average lead time for a prototype at our facility is approximately 3 days, provided the models are print-ready.
Checklist for Cost-Efficient Ordering
- File Audit: Is the model "watertight" (manifold) and free of errors?
- Material Check: Is PLA sufficient for the function, or is ABS mandatory?
- Infill Optimization: Is 100% filling truly necessary, or is 20% enough?
- Orientation: Has the part been oriented to minimize support structures?
- Surface: Is the raw print quality sufficient, or is paid post-processing planned?
