This is a command-line tool written in Go that calculates the cost of producing a 3D-printed object based on user-provided specifications. It uses a JSON file to store material data, allowing easy updates to material costs without modifying the code.
- Interactive CLI for entering object weight, print time, and material selection.
- Dynamic loading of materials from a JSON file.
- Simple cost calculation based on material, machine, and labor costs.
- Easy extensibility for additional cost factors.
Ensure you have Go installed (version 1.17 or later). Then, clone the repository and initialize the project:
# Clone the repository
git clone https://github.com/yourusername/3d-printing-calculator.git
cd 3d-printing-calculator
# Initialize Go module
go mod tidyRun the program from the project root:
go run cmd/app/main.goThe program will prompt you to enter:
- Estimated weight (in grams)
- Estimated print time (in hours)
- Material selection (from the available options)
It will then calculate and display the total cost.
Material data is stored in materials.json in the project root. You can modify this file to update material prices or add new materials.
Example format:
[
{ "name": "PLA", "costPerGram": 0.10, "density": 1.24 },
{ "name": "ABS", "costPerGram": 0.12, "density": 1.04 }
