About

EasyPrint extension

This extension allows a web application to connect to printers on your local network. It bypasses browser security restrictions that prevent direct access to printers without built-in security features, offering a more convenient way to send print jobs.

Highlights
  • Connects to local network printers
  • Bypasses browser security restrictions
  • Enables sending print jobs from web apps
  • Optional installation for convenience

This extension enables EasyPrint to communicate with printers located on internal networks. Since these printers typically lack built-in security, modern browsers correctly block direct access to them from web applications like EasyPrint. Installing this extension is entirely optional. It simply provides a more convenient way to send print jobs from EasyPrint to your local printer.

About

3D Topology Optimizer

Features
Read full description

3D Topology Optimizer reduces the weight of a 3D part without sacrificing its strength — entirely on your device, with no cloud upload required. Load an STL model, mark contact surfaces, applied loads (forces and moments), and functionally important faces that must never change. The app then runs a real finite-element simulation and a SIMP topology optimization directly on iPhone, iPad, or Mac to determine which material actually contributes to strength and which can be removed. FEATURES • Automatic hole detection — cylindrical bores are recognized and automatically protected from the optimizer • Calculated entirely on-device — your geometry and load cases never leave your device • High-resolution STL export for 3D printing or CNC machining • Built-in parametric templates (bushings, brackets) to get started without any CAD file • Wireframe and shaded 3D viewer with axis indicators for precise face tagging WHO IT'S FOR Engineers, product designers, makers, and students who design 3D-printed or CNC-machined parts and want a fast, private way to see where material can be safely removed before committing to a print or a machining run. All calculations are a simplified, linear finite-element approximation and do not replace certified FEA software or review by a qualified engineer. Always verify results independently before manufacturing load-bearing parts.

Verdict

The call

The clearest difference is in-app purchases: EasyPrint extension at none against 3D Topology Optimizer's 1. EasyPrint extension also leads on ads (none vs shown) and iOS requirement (15.0 vs 17.0). 3D Topology Optimizer's advantage is update cadence (every 6 days vs every 2 weeks). On price and device support there is nothing between them.
