Your guide to correct file handling, formats, and understanding the actual costs behind your quote
You have a finished file and want a price now. You do not have time for long email correspondence. Therefore, we use an automated price calculator that gives you an answer immediately. This guide shows you exactly how to operate the tool correctly so you get a valid quote instantly. We also review why the price looks the way it does, so you understand the mechanics behind the numbers.
How do you prepare your 3D file for upload?
A precise price requires precise data. Your file acts as the recipe for our 3D printers. If the recipe contains errors, the calculation or the 3D print itself fails.
You should always export your file in millimeters (mm). Many drawing programs export by default in inches or centimeters. If you upload a file drawn in inches, but the system reads it as millimeters, your model becomes 25.4 times too small. This results in a price close to 0 INR, which is a clear indicator of an error.
The choice of file format also affects the quality of your quote. We recommend the following formats depending on your needs:
| File type | Recommended use | Advantage | Disadvantage |
| STL | Standard 3D print | Supported by all systems | Can contain geometry errors |
| STEP / STP | Professional / Engineer | Highest precision | Often contains more data |
| OBJ | Visual models | Saves colour/texture info | Not ideal for mechanical parts |
When the system analyses your file, it automatically adds a safety buffer to the material calculation. In the industry, we call this an “efficiency factor” of approx. 1.1. This means that the calculator takes into account 10% extra material consumption. This covers so-called “purge towers,” which clean the nozzle along the way, as well as necessary support structures. This factor ensures that the price holds, even if the production requires a little extra material to succeed.
How to use the price calculator correctly?
The calculator itself functions as a lightning-fast “slicer.” A slicer is the software that cuts your 3D model into thousands of layers to calculate the exact 3D print time.
The process is simple. You save your file as STL or STEP on your computer. Then you drag the file directly into the upload field on our page. The most important step now is to check the measurements (L x W x H) on the screen immediately. Do they look correct? If your model for a mobile cover is listed as being 2 meters long, you must rescale the file in your drawing program before proceeding.
When you choose technology and material, the price updates instantly. The system does not just look at the amount of plastic. It simulates the actual time a 3D printer must run. A complex item can take exactly 5.1 hours to print, and it is this machine time that drives the majority of the price.
How do material choice and infill affect the price?
Many mistakenly believe that the price drops by half if you choose a material that is half as expensive. That is not how reality works within professional manufacturing.
We can look at a concrete example with a simple reveal spacer. The raw material (filament) for this part might only cost 115.00 INR. However, the total price for the part typically lands at around 680.00 INR.
The reason is that the machine spends the same amount of time running, regardless of whether it melts cheap PLA or the more expensive PETG. Therefore, the price only changes slightly when switching materials, as the raw material constitutes the smallest part of the total cost.
You influence the price most effectively by adjusting the “infill” (degree of filling) in your design. A solid block takes a long time to print. A block with 20% infill is almost as strong but much faster to produce. Therefore, choose the lowest possible acceptable infill to reduce your 3D print price.
What does your 3D print price actually consist of?
When you see the price on the screen, you are seeing the result of a calculation we call “Landed Cost” or total costs. We believe in transparency, so here we review the four elements you are paying for.
Firstly, you pay for machine costs. A 3D printer slowly wears down while it works. A typical industrial machine has an effective lifespan of approx. 13,000 active print hours, which corresponds to roughly 3 years in a busy production. Every hour therefore costs money in pure depreciation and ongoing maintenance.
Secondly, you pay for electricity. A professional 3D printer draws an average of 150 watts per hour. This corresponds to a powerful old-fashioned incandescent bulb glowing constantly for 5 to 20 hours per item, depending on the size.
Thirdly, the price covers labour. Even though the process is digital, each item requires manual handling. A technician typically spends 2 to 5 minutes per part starting the machine, removing the item, cleaning off small defects (“boogers”), and packing it securely.
Finally, there is the material. As mentioned earlier, the raw material itself often constitutes the smallest part of the total price. You are primarily paying for access to a calibrated machine and a technician’s time, rather than for the gram weight of the plastic.
How do you avoid the most common 3D print price errors?
If the calculator rejects your file or shows a warning, it is often due to geometric errors in the file. Your file must be “manifold”. In short, this means it must be watertight. Imagine filling your digital model with water. If the water leaks out through a hole in the surface, we cannot produce it as a 3D print.
You should check your file for three specific errors before upload. Look for “Non-manifold edges”, which are holes in the model’s surface. Check for “Inverted normals”, where the system thinks the inside is facing out. Also, be aware of wall thickness. If a wall is thinner than 0.8 mm, the nozzle cannot physically print it, and the part will break.
Most modern CAD programs have a repair function. Use this function before exporting to ensure a trouble-free price calculation.
What does the price of a 3D print consist of?
The price primarily consists of machine hours, manual labour, electricity, and depreciation on the equipment, not just material. Even a small item requires manual handling by a technician, which creates a minimum price. We calculate the total costs to ensure high quality and reliable delivery of your finished 3D print.
Why does my price become very low or 0 INR?
This error typically occurs if your file is exported in inches but loaded as millimeters, making the model microscopic. Check your export settings in your CAD program and ensure the unit is set to millimeters (mm). Upload the file again to see the correct price immediately.
Which file format should I use for 3D print?
We recommend STEP files for professional precision or STL files for standard models. STEP preserves curved geometries better, while STL is the standard for most systems. Always export your files in millimeters to ensure that dimensions are read correctly by our online price calculator.
Does it become cheaper if I choose a different material?
A change of material rarely halves the price, as machine time remains the same regardless of plastic type. The raw material often constitutes the smallest part of the total cost. You save more money by reducing the infill percentage in your design, as this significantly reduces the actual print time and thus lowers the price.
How thin walls can one 3D print?
Your design should generally have a wall thickness of at least 0.8 mm to be printed successfully. Walls thinner than this cannot be physically formed by the nozzle of a 3D printer and will result in a fragile item. Use the repair function in your software to correct thin walls before upload.
How is the time for my 3D print calculated?
Our calculator functions as a digital slicer that simulates the exact movements of the print head layer by layer. It calculates the precise time based on geometry, volume, and complexity. This specific machine time is the most important factor for the final price you see on the screen when ordering.
Checklist for your 3D print price
You ensure the best result by following a fixed routine. Always export your files in millimeters (mm) to avoid scaling errors. Use the STEP format if you need maximum precision, or STL if you need it to be fast.
Always remember to check the measurements on the screen as soon as you have uploaded the file. Be aware that the price reflects machine time and technician hours more than material consumption. Finally, ensure that your model is “watertight” (manifold). By following these steps, you get the most accurate price and the fastest delivery flow for your 3D print.
