3D Printing Optimizer for a gas law

Simulate a gas law live in your browser. This runs the real 3D Printing Optimizer solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.

Thermal Expansion

Thermal ExpansionLive

Controls

Presets

Heat a material and it expands: ΔL = α·L·ΔT, where α is the coefficient of linear expansion. Area grows at twice that rate and volume at three times. It is why bridges have expansion joints, why rails buckle in heat, and why Invar — with almost zero expansion — is prized for precision instruments.

▶ Run in Python

Data Inspector

α23 µm/m·°C
Length change11.5 mm
Area change0.230 m²
Volume change3.450 m³

Governing equation

Reading this result: Heating 10 m of Aluminum by 50°C stretches it about 11.5 mm; area and volume grow 2× and 3× as fast.

Stress Strain

Stress-Strain CurveLive

Controls

Presets

Pull on a material and its stress-strain curve tells its story: a straight elastic region with slope equal to Young's modulus, a yield point where permanent deformation begins, a peak at the ultimate tensile strength, and finally fracture. Ductile metals stretch far; brittle ones like cast iron snap with almost no warning.

▶ Run in Python

Data Inspector

Young's modulus200 GPa
Current stress294 MPa
UTS400 MPa
Regionplastic

Governing equation

Reading this result: Past yield (250 MPa): Mild steel is deforming permanently and hardening toward its 400 MPa ultimate strength.

About this simulation

The full 3D Printing Optimizer tool models a gas law with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions

How do I simulate a gas law?
Open this page and use the live 3D Printing Optimizer tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
Can I use my own numbers?
Absolutely — every input is adjustable, and with data import you can drive a gas law from your own measurements.
