How to choose a 3D pens

Updated June 2026Independently researchedNo paid placement.

What should you look for in a 3D pen for kids vs adults?

Safety is the biggest split. Pens for kids often run at lower nozzle temperatures (around 160–190°C) using PLA or PCL filament, which reduces burn risk. Adult-oriented pens go higher (up to 230°C or more) to work with ABS, PETG, or flexible materials, giving stronger, more durable results. Controls matter too. Kid-friendly designs tend to have a single button or simple slide for speed, while adult pens offer separate temperature and speed dials. Nozzle shape also differs, kid models may have a rounded silicone cover to prevent burns, whereas adult pens have exposed ceramic nozzles for finer detail. Look for auto-shutoff after a few minutes of inactivity, regardless of who will use it.

Is there a learning curve with 3D pens?

Yes, but it’s shorter than you might think. Most beginners can make a basic 2D shape within a few minutes, but 3D drawing requires practice, controlling the speed you extrude, moving your hand at a steady pace, and building up layers without letting the filament sag. Start with provided stencils or traceable patterns. Once you’re comfortable, try freehand shapes. Some pens include a speed slider that lets you go slow for control and fast for filling in large areas. Expect a few wobbly attempts before your lines become smooth, that’s normal. The best way to learn is to watch a few online tutorials and then just play with scrap filament.

What types of filament work best for 3D pens?

For kids and first-timers, PLA or PCL is the safest bet. PLA smells faintly like waffles when heated, prints at low temperatures, and sticks well to most surfaces. PCL (polylactic acid variant) is even lower-melting and is often used in pens designed specifically for children. Both are non-toxic and biodegradable. Adults who want stronger, more flexible models should try ABS. It’s tougher and can be sanded or painted after printing, but it requires a heated build surface (usually a glass bed) and produces a slight plastic odor. PETG sits in the middle, stronger than PLA, easier than ABS, and with less odor. Avoid nylon or polycarbonate in most pens because they need very high temperatures that typical pens can’t reach.

How important is adjustable speed and temperature?

Very important if you plan to do more than basic doodling. Adjustable speed lets you go slow for precise lines and details or fast for filling in large areas and creating solid objects. Without it, you’re stuck at one rate, which makes delicate work frustrating. Temperature control is equally useful for swapping between different filaments, PLA requires lower heat, ABS needs higher. Some pens have a knob or buttons to adjust in small increments; others offer preset modes. If you only ever use one filament type, a fixed-temperature pen can work fine, but it limits your material choices down the road.

Are cordless or corded 3D pens better?

Cordless pens offer freedom of movement, you can draw on larger surfaces, reposition easily, and avoid tangling the cable. The trade-off is battery life: most cordless models run for 30 minutes to an hour on a full charge, which may be enough for short projects but frustrating for longer ones. They also tend to be heavier because of the battery. Corded pens provide consistent heat and unlimited runtime. They’re lighter and often cheaper for the same feature set. The cord can be a minor annoyance, but with a bit of management (like clipping it to your desk or using a stretchy cable) it’s rarely a dealbreaker. For kids, a cord is safer, no risk of forgetting to recharge and then having the pen cool mid-drawing.

What safety features matter most?

Look for an auto-shutoff that turns the pen off after a few minutes of inactivity, this prevents accidents if it’s left on. A low-temperature mode (often labeled “PLA”) is safer for children because the nozzle stays below 180°C. Some pens include a silicone protective cap over the nozzle that reduces burn risk if touched. Also check for a non-slip grip and a stand to hold the pen when not in use. Many pens come with a small silicone mat to work on, which protects surfaces and makes cleanup easier. Make sure the power adapter has overcurrent protection if it’s a corded model.
