## Tool capabilities

| Property | Value |
| --- | --- |
| Tool ID | `resin-volume-calculator` |
| Category | calculators |
| Implementation | Registered implementation. Registration alone is not a production-quality guarantee. |
| Browser execution | Automatic updates after valid input or file selection. |
| Browser processing | Browser; see tool notes for network behavior. |
| HTTP API | Not callable through HTTP. |
| Browser-agent interface | run_current_tool |

### Implementation notes

Find total mixed resin for a cast or coating, subtract inserts and add an allowance. This does not determine component ratios or permitted pour depth. Changing units keeps the entered numbers. Calculations run on your device.

### Inputs and settings

No free-text input is required. Use the file inputs and/or settings below.

| Setting | Meaning | Control type | Default | Constraints |
| --- | --- | --- | --- | --- |
| `shape` | Measure | select | "Rectangular cast" | Allowed: Rectangular cast, Cylindrical cast, Coating by area, Known volume |
| `length` | Internal cast length | number | 20 | min=0 max=1000000000 step=any |

### Browser-agent workflow

1. Open the human page in a browser that supports WebMCP.
2. Discover the interface exposed by that page; use its actual schema.
3. Select files on the page first when the tool requires files.
4. Call `run_current_tool` with valid input and settings.
5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.

Calls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.

### Planning specification

Up to 10,000 identical pieces or layers. Displacement must be smaller than gross volume. No shrinkage, absorption or maximum-pour-depth value is guessed.

This describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.

### How to use Resin volume calculator

1. Enter your measurements, rates or supplied recipe.
2. Review the quantities, rounding and plan details.
3. Download the result and verify it against your actual materials or a sample.

## Useful next steps

- [Epoxy ratio calculator](https://happytails.ai/en/calculators/epoxy-ratio-calculator/) ([Markdown](https://happytails.ai/en/calculators/epoxy-ratio-calculator.md))

- [Candle wax calculator](https://happytails.ai/en/calculators/candle-wax-calculator/) ([Markdown](https://happytails.ai/en/calculators/candle-wax-calculator.md))

## Measure the space resin will fill

Use internal cast dimensions and the intended depth. Coating mode uses area multiplied by thickness. Subtract the volume of inserts once per piece; the remaining space must be positive.

### Add identical pieces and allowance

A 20 × 10 × 2 cm rectangular space holds 400 mL. Adding 10% gives 440 mL of mixed resin. The output is the combined volume, so use the ratio tool separately for component amounts in the basis required by the product.

### Save the plan

Download the result as CSV, plus a text or JSON report with formulas, values and assumptions. Everything is calculated on your device. Changing units keeps the entered numbers, so check the selected units before using the plan.
