Project Specification: Extrusion Multiplier & Squish Calculator
1. Overview
A browser-based, high-precision utility for 3D printing enthusiasts to calculate their optimal extrusion multiplier and refine their first-layer settings. The tool replaces guesswork with mathematical precision using measured wall thickness data.
2. Core Functional Requirements
- Extrusion Multiplier Input Section:
- Fields for 'Current Extrusion Multiplier' (e.g., 1.00).
- Fields for 'Expected Wall Thickness' (e.g., 0.4mm).
- Fields for 'Measured Wall Thickness' (input from calipers).
- Calculation Engine:
- Formula:
New Multiplier = (Expected Thickness / Measured Thickness) * Current Multiplier.
- Formula:
- Results Section:
- Clear display of the 'Suggested Extrusion Multiplier'.
- 'Percent Difference' indicator to show the magnitude of the adjustment.
- Copy-to-clipboard button for the result.
- Educational Tooltips: Embedded icons that reveal helpful definitions (e.g., 'What is Extrusion Multiplier?') via CSS-only popovers.
3. UI/UX & Aesthetics
- Design Language: Clean, modern, minimalist SaaS aesthetic. High contrast, sharp typography, and spacious padding.
- Color Palette:
- Background: #ffffff
- Surface: #f9f9fb (very light gray for cards)
- Primary Text: #1a1a1a
- Primary Accent (Blue): #0066cc (for call-to-action buttons)
- Success Green: #28a745 (for result highlights)
- Border: #e0e0e0
- Animations:
- Smooth fading transitions when calculating results.
- Subtle scale-up effects on hover for primary action buttons.
- Soft box shadows (0px 4px 6px -1px rgba(0,0,0,0.1)) to separate components from the background.
4. Technical Constraints (Strict Compliance)
- Architecture: One single
.htmlfile. CSS/JS embedded within<style>and<script>tags. - No State Persistence: Do not use
localStorage,sessionStorage, or cookies. The application must calculate based strictly on user input per session. - Sandbox Safety:
- No
alert(),prompt(), orconfirm(). All feedback/errors should be custom HTML/CSS modals or inline text. - All external links (if any) must include
target="_blank" rel="noopener noreferrer".
- No
- Responsive: Fluid layout using Flexbox/Grid. Inputs must be stacked on mobile (vertical) and side-by-side on desktop (horizontal).
5. Development Guidelines
- Use a standard UI font (Inter, system-ui, or sans-serif).
- Maintain a strictly 'Light Mode' aesthetic. Ensure all text passes WCAG contrast ratios.
- Keep the code readable and well-commented for future maintenance.

Frequently Asked Questions
Everything you need to know about using this application.
What is the importance of first layer squish in 3D printing?
First layer squish refers to how much the plastic is compressed against the print bed during the initial layer. Achieving the correct amount of squish is critical for ensuring excellent bed adhesion and preventing warping or prints detaching during the process. When the squish is too low, the part will not stick to the build plate. Conversely, if the squish is too high, the nozzle may drag through the plastic, causing clogs and damage to the print surface. Proper calibration ensures a durable, professional-grade base for your model.
How do I calculate the correct extrusion multiplier?
To calculate the new extrusion multiplier, you first measure the wall thickness of a test print using digital calipers. You then divide the expected wall thickness by the actual measured thickness and multiply the result by your current extrusion multiplier value. This simple math allows you to compensate for under-extrusion or over-extrusion precisely. Our calculator automates this formula, taking the guesswork out of calibrating your material flow rate for different filaments like PLA, PETG, or ABS.
Why is flow rate calibration necessary for different filaments?
Every filament brand and material type has slightly different thermal properties and flow characteristics. Even if two filaments are labeled as the same material, the pigment additives and base plastic quality can result in varied extrusion volumes. Regularly calibrating your flow rate—also known as the extrusion multiplier in many slicers—prevents common defects like rough top layers, bulging corners, and dimensional inaccuracy. Consistency is the key to high-quality 3D printing results.
Does this calculator work with my 3D printer slicer?
Yes, this tool is slicer-agnostic. Whether you are using Cura, PrusaSlicer, Bambu Studio, or OrcaSlicer, the extrusion multiplier math remains the same. You simply calculate the adjustment here and update the corresponding 'Flow' or 'Extrusion Multiplier' setting in your software. By ensuring your hardware settings match your software configuration, you maintain absolute control over your print quality. This tool is designed to work seamlessly with all FDM-based 3D printers, regardless of brand or model.
