Your 3D printer is already a precision robot

Manual Testing

Repetitive manual taps are slow and inconsistent
Physical button testing requires precise finger placement
No way to reproduce exact touch sequences
Testing multiple devices means starting from scratch each time
Human error makes results unreliable

With Touch Automation

Your 3D printer already has sub-millimeter positioning
Print our free stylus mount — no extra hardware to buy
Repeatable G-code sequences for every interaction
25 phone models with accurate dimensions and button positions
Collision detection prevents stylus, bed, and phone damage

5 touch presets

Ready-to-use interaction patterns that generate valid G-code for your printer.

👉

Tap

Single precise tap at any screen coordinate. The stylus descends vertically to touch the screen surface, then retracts. Configurable screen position as X/Y percentage.

Screen X% Screen Y% Approach height

⏲

Long Press

Touch and hold at a screen position for a configurable duration. Triggers context menus, drag initiation, or hold-sensitive UI elements.

Screen X% Screen Y% Hold duration

↔

Swipe

Linear swipe gesture between two screen coordinates. Control the swipe speed for scrolling, dismissing notifications, or navigating between screens.

🔨

Multi-Tap

Rapid repeated taps at the same screen position. Configurable tap count and interval for double-tap, triple-tap, or custom sequences.

Press Button

Press a physical side button (volume, power, action) using a horizontal side-approach pattern. The stylus lowers to button height, approaches from the side, and presses with its cylinder surface.

Built for precision

Every touch coordinate is compensated for your exact hardware setup.

Stylus Calibration

Configure stylus length, diameter, and X/Y offsets from the nozzle. The simulator compensates all touch coordinates so the stylus tip lands exactly where intended.

Kinematics-Aware Offsets

Cartesian printers (bed-slingers) and CoreXY printers handle Y-axis offsets differently. PrintPilot automatically applies the correct compensation based on your printer's kinematics.

Collision Detection

Three collision checks protect your hardware: stylus vs. printed parts, stylus tip vs. bed surface, and stylus cylinder vs. phone body. Warnings appear in real-time during simulation.

What you can do with Touch mode

QA Automation

Run repeatable touch test sequences across multiple phone models. Verify UI interactions, button responses, and gesture recognition with consistent, measurable precision.

Accessibility Testing

Test screen interactions at precise coordinates to verify touch targets meet accessibility guidelines. Reproduce edge-case tap positions that are hard to hit manually.

Content Creation

Automate repetitive phone interactions for content creation workflows. Program tap sequences for app navigation, screen recording triggers, or social media automation.

Frequently asked questions

What stylus and mount do I need?

We're working on a free 3D-printable stylus mount designed for the best compatibility with PrintPilot (coming soon). Any capacitive stylus will work. The simulator lets you configure exact stylus dimensions — length, diameter, and offset from the nozzle — so the G-code compensates for your specific setup.

Does Touch mode work with any 3D printer?

Touch mode generates standard G-code (G0/G1 moves), so it works with any FDM printer that accepts G-code. The 14 built-in printer profiles include accurate travel ranges and kinematics settings for optimal results.

How accurate is the positioning?

3D printers typically achieve 0.05–0.1mm positioning accuracy, which is more than sufficient for screen touch interactions. The simulator accounts for stylus offsets and kinematics to place the tip precisely on the target screen coordinate.

Can it press physical buttons?

Yes. The Press Button preset uses a side-approach pattern. The stylus lowers to the button's height, approaches horizontally, and presses with its cylinder surface rather than the tip. This works for volume, power, and action buttons on all supported phone models.

What if my phone model isn't listed?

You can define custom phone dimensions including body width, height, thickness, screen size, and button positions. The custom phone option gives you full control over all measurements.
