3Dsimo Gold 3D pen and multifunction tool by 3Dsimo (model 3Dsimo-Gold)

3Dsimo Gold is a compact, handheld 3D pen and multifunction tool designed for freehand 3D drawing, crafting and small repairs. It provides controlled extrusion of thermoplastic filament for creating models, prototypes and decorative elements. The tool is intended for makers, hobbyists and educational settings where portable, precise manual 3D shaping is required.

Advantages

3Dsimo Gold combines the portability of a pen-style device with adjustable extrusion for precise detailing. Its compact form factor supports extended handheld use and easy transport. The device enables accurate filament deposition for fine lines and layered builds, allowing users to produce functional parts, visual prototypes and decorative accents without large equipment. Its multipurpose design accommodates creative work, craft projects and minor repair tasks.

Suitable for

• Freehand 3D drawing and sculpting of small models
• Rapid prototyping of simple parts and concept models
• Decorative detailing on crafts, home items and cosplay props
• Minor repair tasks where small amounts of thermoplastic are needed
• Educational demonstrations and hands-on maker workshops

Key specifications

• Handheld, pen-style form factor for manual 3D extrusion
• Compatible with thermoplastic filaments suitable for handheld extrusion
• Adjustable extrusion control for varied line thickness and flow
• Compact dimensions and lightweight design for portability
• Designed for precision work on small-scale models and details

How to use

Load a compatible filament into the device following manufacturer guidelines, set the desired extrusion speed and temperature if adjustable, and begin drawing by guiding the tip along the work surface or through the air to build up layers. Use steady hand movements for even lines and pause between passes to allow filament to cool and solidify where needed. For repairs, apply short extrusions to fill gaps or meld parts together, then trim or sand once cooled for a clean finish.

Usage recommendations

Work on a heat-resistant surface and use eye protection if required. Keep the device tip clear of debris and follow filament manufacturer instructions for optimal temperature and handling. Allow finished parts to cool fully before handling and store filaments in a dry place to prevent moisture absorption.
