To use a 3D printing pen, select the setting that matches your filament, wait for the pen to heat, feed the filament until it engages, and draw with controlled extrusion. Begin with simple shapes on paper; the nozzle gets hot, so work in a ventilated area and follow your pen’s manual.
Before you start: match the filament to the pen
Use only filament approved for your model and select its corresponding material setting. A mismatched setting can cause poor feeding or a jam. Pen controls and compatible materials vary, so check the manual before loading.
| Material | Setting and temperature information | Practical notes |
|---|---|---|
| PLA | Use the PLA setting. The original 3Doodler guide lists approximately 190–200°C. | A practical starting material for drawing on a surface. 3Doodler’s tutorial covers basic drawing techniques. |
| ABS | Use the ABS/FLX setting. The original 3Doodler guide lists approximately 230–240°C. | The drawing guide describes ABS as easier to control for drawing in the air. Use ventilation. 3Doodler’s tutorial |
| FLEXY | Create+ supports FLEXY on the ABS/FLX setting. | Verify the exact pen and refill specifications before use. Create+ manuals |
| Flow-compatible 1.75 mm filament | Flow’s troubleshooting guide describes compatible spooled filament within a 160–220°C range, with the setting matched to the material. | This guidance applies to Flow-compatible filament and the Flow pen, not every 3D pen. Flow troubleshooting |
These temperatures are product-specific guidance, not universal settings. Do not apply one pen’s temperature range to another model.

How to use a 3D printing pen
- Prepare a safe workspace. Clear the work area and provide ventilation. Keep the pen away from skin, water and flammable materials. The Create+ manual warns that the nozzle is hot and calls for a well-ventilated area.
- Select the material setting. Choose PLA for PLA filament, or ABS/FLX for ABS or FLEXY when your model supports it. Confirm the pairing in your manual.
- Heat the pen. Wait for its ready indicator before loading or drawing. On the original 3Doodler guide, heating takes approximately one minute; blue indicates ABS and green indicates PLA. Other pens may use different indicators and take different amounts of time. Original 3Doodler tutorial
- Insert the filament. Press the drive control, place the strand in the rear opening and push gently until the feed mechanism grips it. Give the filament a few seconds to reach the nozzle and begin extruding. Create+ getting started
- Practice on paper. Rest the nozzle on the surface, extrude a short line, then lift. Try straight lines, circles and a grid before moving on to upright or air-drawn forms. 3Doodler drawing guide
- Adjust the flow to the task. Use the slow control for corners and detail, and the fast control for longer lines. Button names and control layouts depend on the pen model. Create+ getting started
- Change filament safely. Stop extrusion and remove the strand using the procedure for your model. Trim the softened end if needed, then load a compatible strand. Do not pull or force filament against the pen’s instructions. Create+ manuals
How to improve your lines and shapes
Build control on a flat surface first
Keep the tip close to the paper and move at a steady pace while extruding. If a line piles up, reduce the flow or move the pen more consistently. If it breaks, check that extrusion is active and the filament is feeding before changing your drawing technique.

Move from outlines to raised forms
After practicing flat lines and closed shapes, draw a base and add short supports or walls. Allow each section to cool and firm before attaching the next. Air drawing requires more control than tracing on a surface; the 3Doodler guide notes that ABS can be easier to control in the air, but only use it with the correct setting and suitable ventilation. 3Doodler drawing guide
Troubleshooting: filament will not feed or the pen is jammed
Start with the simplest likely causes: an incorrect material setting, a strand that has not engaged the feed mechanism, or a clog. Use only the troubleshooting steps approved for your model.
