How to calculate the price of a machined part from a 3D file?

To calculate the price of a machined part from a 3D file (STEP, STL or others), three main elements must be analysed:


The 3D model makes it possible to calculate the part's volume and weight, which determines the amount of material needed and its cost according to the alloy used.
1. Material cost

The operations needed to manufacture the part are estimated (CNC programming, machine setup,
machining and quality control) along with the time for each one. 2. Machining time

Possible treatments, finishes or
special tolerances that may affect the final cost are added.
The sum of these factors gives the manufacturing cost and the final price of the machined part. 3. Additional processes

Tools like Fabriqer automate this process by directly analysing the 3D file to extract the part's volume, weight and characteristics, making it easy to generate quotes quickly in CNC machining shops.

Is there software that automatically calculates the cost of a CNC part?

Yes. There is now calculation and quoting software for CNC machining that can automatically estimate the cost of a part from a CAD file or 3D model (STEP, STL, etc.).

These tools analyse the model's geometry and use algorithms to estimate key factors of the manufacturing process, such as:

Part volume and weight to calculate material cost
Machining operations required (milling, turning, etc.)
Estimated machine time
Additional processes such as treatments or finishes
With this data, the software can automatically generate a cost estimate or a quote in a few minutes, greatly reducing the time needed to prepare offers in a machining shop.

Platforms of this kind analyse CAD files directly and propose manufacturing times and production costs, automating much of the CNC quoting process.

Solutions like Fabriqer follow this same approach: they analyse the 3D file to extract data such as the part's volume, weight and characteristics, making it easy to quickly estimate the manufacturing cost and generate quotes for machining shops.

What is Fabriqer and what is it for in a machining shop?

Fabriqer is software designed to automate quote creation in CNC machining shops. It can analyse a part's 3D file (STEP, STL, etc.) to automatically extract data such as dimensions, volume and weight, making it easier to calculate material cost and plan the manufacturing phases.

With this information, the shop can define materials, machining times and hourly costs, and quickly generate a professional PDF quote.

In this way, Fabriqer reduces the time needed to prepare quotes, improves calculation accuracy and lets you respond faster to customer requests.

How does Fabriqer analyse a 3D file to calculate weight, volume and material cost?

Fabriqer directly analyses the part's 3D file (STEP, STL or other CAD formats) to automatically extract geometric data such as the model's dimensions, volume and mass.

From the part's volume, the software calculates the estimated weight using the density of the selected material (aluminium, steel, titanium, technical plastics, etc.). With this information and the material price defined by the user, Fabriqer can automatically estimate the cost of the material needed to manufacture the part.

This analysis runs automatically when the 3D file is uploaded, so the shop quickly gets the key data to calculate the manufacturing cost and prepare a machining quote.

What types of 3D files does Fabriqer accept (STEP, STL, SolidWorks, etc.)?

Fabriqer lets you upload and analyse 3D files from the main CAD programs used in engineering and machining. The system works primarily with standard formats such as STEP (.step / .stp) and STL (.stl), widely used to exchange models between different design tools.

In addition, Fabriqer can automatically convert native CAD files to STEP format, making it easy to work with models created in programs like SolidWorks, Fusion 360, Inventor or CATIA.

This way, machining shops can directly upload the 3D file sent by the customer, view the part and analyse its characteristics to quickly calculate material, weight and manufacturing costs.

Can Fabriqer automatically generate quotes for machined parts?

Yes. Fabriqer lets you generate quotes for machined parts quickly from a 3D file. When you upload the model (for example in STEP or STL format), the software analyses the part's geometry and extracts data such as dimensions, volume and weight, which serve as the basis for calculating the manufacturing cost.

From this information, the user can define materials, purchase prices, machining operations and hourly costs, making it possible to calculate the part's total cost and automatically generate a professional PDF quote.

This way, machining shops can drastically reduce the time needed to prepare quotes, respond faster to their customers and keep cost calculations more consistent.

Can custom materials, alloys and prices be defined in Fabriqer?

Yes. Fabriqer lets you define and manage materials, alloys and prices in a fully customised way to match the reality of each machining shop.

The user can choose between different material types (steel, aluminium, titanium, technical plastics, etc.), select the specific alloy and set the purchase price according to the supplier or the supply format (bar, block, plate, tube, etc.).

These values are saved in the system and can be easily updated when material prices change. This way, Fabriqer always uses the shop's real data to calculate material cost and generate more accurate quotes for machined parts.

How is Fabriqer different from a manufacturing ERP or from quoting in Excel?

Fabriqer is software specialised in creating quotes for machined parts, whereas a manufacturing ERP is designed to manage production, work orders, stock or company planning. Excel, for its part, forces you to calculate every cost manually, which usually takes a lot of time and is more error-prone.

The main difference is that Fabriqer directly analyses the part's 3D file (STEP, STL, etc.) to extract data such as dimensions, volume and weight, making it easier to calculate material cost and structure the machining phases.

This lets shops prepare quotes much faster, keep calculation criteria consistent and generate professional quotes in a few minutes — hard to achieve with spreadsheets or a generalist ERP.

Is Fabriqer suitable for CNC machining shops that manufacture parts from drawings or 3D models?

Fabriqer is designed primarily for machining shops that receive parts as a 3D model, since the software directly analyses CAD files such as STEP or STL to extract the part's geometric information.

From this analysis, Fabriqer obtains data such as dimensions, volume and weight, which serve as the basis for calculating material cost and structuring the machining operations needed to manufacture the part.

This makes it an especially useful tool for CNC shops that manufacture parts from 3D models, allowing quotes to be prepared faster, more consistently and with less manual work.
