3Doodler Start Refills: Which Fit, Packs and Compatible Alternatives
The 3Doodler Start and Start+ don’t take the standard filament used by other 3D pens. They need their own plastic strands. Here is which refills fit, what the packs contain, how official and third-party strands compare, and how to store them.

Key takeaways
- The Start and Start+ use 3Doodler Start plastic strands, not the PLA or ABS filament used by high-temperature pens.
- The official 250-strand bag costs $31.01 on Amazon.com (checked Nov 8, 2026).
- Some third-party brands sell strands advertised as compatible with the Start. Check the listing explicitly says “3Doodler Start”.
- Refills for the 3Doodler Create+ or Flow (pens for teens and adults) do not fit the Start.
Which refills fit the 3Doodler Start and Start+?
| Pen | Plastic it takes |
|---|---|
| 3Doodler Start / Start+ | 3Doodler Start strands (low-temperature, own format) |
| 3Doodler Create+ / Flow and most other 3D pens | Other formats: standard 1.75 mm PLA or ABS for most high-temperature pens |
The Start was designed for kids and uses soft, low-temperature plastic. That is why regular 3D pen filament doesn’t work in it, and Start strands don’t work in high-temperature pens.
Official 3Doodler Start refills
price checked Nov 8, 2026
The official bag from 3Doodler with 250 strands in assorted colors, made for the Start and Start+. Official strands are the safe choice for the warranty and for avoiding jams: they have the length and diameter the pen expects.
View on Amazon*Compatible third-party refills
Several brands sell large boxes of strands advertised as compatible with the 3Doodler Start, often with more colors for the money. Before buying:
- Make sure the listing explicitly says it fits the 3Doodler Start / Start+, not just “3D pens”.
- Don’t rely on the stated diameter alone: listings for Start strands give different values, so the listing itself should name the Start.
- Read recent reviews for jams or color quality.
- Keep in mind that a pen problem caused by non-official plastic may not be covered by the warranty.
We will add compatible packs here once we have checked them on Amazon.com.
How much plastic do you need?
A simple flat shape uses a strand or two; a bigger 3D project uses many. Kids who use the pen every week go through a starter set quickly, so a refill pack with a wide mix of colors is a useful add-on to a gift.
Storing refills
- Keep strands straight and in their box: bent or squashed strands feed poorly.
- Store them away from heat and direct sunlight, as low-temperature plastic softens easily.
- Use full-length strands: very short leftovers are more likely to get stuck.
