three. Toys, games and fun for kids

1. Building block connectors: Invent unique joints to connect LEGO® or wooden blocks. hint: Calibrate dimensions carefully.
2. puzzle: Design puzzles that connect each other – birds, continents, etc. hint: Ensure a snug fit and not breakable.
3. Mini statue: Create an original character, animal or vehicle. hint: Build the limbs separately and then connect them.
4. Micro car: Simple construction of chassis and wheels. hint: Use a dowel or melted joint as the shaft.
5. Marble Run: Engineers track and support marbles. hint: Prioritize smooth slopes and sturdy supports.
6. Board Game Tokens: Customize the pieces for Checkers or Monopoly. hint: The goal is uniform weight/height.
7. Toy furniture: Craft Dollhouse Chair/Table. hint: Fully strengthen the leg joints.
8. Jointed animals: Use pins to design an animal with articulated limbs. hint: Plan ahead for hinge mechanics.
9. Magic Wand: Spin intricate fantasy wands. hint: Embed wire/beads and pre-cool.
10. Mini building structure: Rebuild a bridge, house or tower. hint: Use templates to make windows/details.

FAQ: Master your 3D pen projects

Question 1: Which filament types are best for different projects?

• People’s Liberation Army: Suitable for beginners (low odor, biodegradable). Ideal for decoration, frames and jewelry (melting temperature approx. 180-200°C). Not very flexible.
• ABS: Stronger and more pliable when cooled. Best suited for functional parts such as clips/connectors (melt >210°C). Ventilation is required.
• Polyethylene glycol: Combines the ease of use of PLA with the durability of ABS. Ideal for items that need to be impact resistant (such as phone stands).
• Flexible filament (TPU): For wearable devices (anklets) that require elasticity. Requires slower pen speed.

Question 2: How to use 3D pen to get a smoother surface?

• Technical adjustments: Draw at a consistent speed slower; pause briefly at endpoints.
• Post-processing: Use 200-grit sandpaper to lightly sand any rough spots. Apply PLA Smoothing Fluid carefully.
• temperature: Higher temperatures (within specs) enhance flow – experiment!

Q3: Why does my filament break/get stuck?

• Moisture: The filaments absorb moisture. Add desiccant to seal and store; briefly preheat.
• Temperature mismatch: Low hot end temperatures will result in increased extrusion pressure. Optimize settings for each filament.
• Nozzle clogged: Clean the tips of acupuncture needles regularly during the warm-up and cool-down period.

Q4: Can I combine 3D pen creation with CAD/other printing?
Absolutely. Example: Use a printed base/stencil to secure the pen design. Digitally export sketches for scalable refinement through platforms like GreatLight’s SLM service, resulting in solid metal prototypes from initial handcrafted concepts.

Q5: Is 3D pen creation suitable for daily use?
Depends on material/design:

• PLA can withstand light duty but will degrade outdoors.
• ABS/engineered polymers are suitable for functional parts.
• For strong performance (load-bearing/mechanical), transition designs to SLA/SLM with professionals – leveraging materials science to extend service life.

Invent boldly—turn sketches into interactive creations, then strategically scale solutions. To achieve unwavering precision, leverage expertise and combine artistry with engineering excellence.
