LEGO Train 12 Volts Posted October 11, 2025 Posted October 11, 2025 Good morning everyone, I don't know if this topic has already been discussed, but I'm just starting out on my 3D printing journey and I wanted to know if anyone knows which red PETG or ABS filament is most similar to Lego pieces. I've tried both PETG and ABS from Sunlu, but I haven't had satisfactory results because the color in both cases is very faded. Any suggestions or advice are appreciated. Quote
dr_spock Posted October 13, 2025 Posted October 13, 2025 I think LEGO red is DD1A21 in hex. https://filamentcolors.xyz/colormatch/ Hatchbox ABS may be close. Finding an exact match can be hard. Shredding, melting, and extruding red LEGO bricks into ABS filament could give an exact match. :-) Quote
LEGO Train 12 Volts Posted October 13, 2025 Author Posted October 13, 2025 Thanks @dr_spock, but I haven't found any matches (have you?). In any case, my question is empirical: has anyone printed in red ABS and been satisfied with the results? Sometimes theory is not the path to take. Quote
