SUNLU PLA+ vs Silk Filaments: Which 1kg Spool to Pick

Best for
Workshop staples for functional prop parts

Best for
Painted props needing earthy and pastel tones

The SUNLU PLA Plus 3D Printer Filament bundle with ten colors packs ten 1kg spools of 1.75mm PLA+ in Coffee Brown, Red, Klein Blue, Green, Vivid Yellow, Sunny Orange, Lavender Purple, Pink, Beige and Oak. That palette leans toward natural and soft tones, which suits wooden-look props, fantasy gear and pieces where the filament color itself does some of the work before paint goes on.

The listing claims PLA+ is three times stronger than PLA, with brighter color, easier use, better layer adhesion and freedom from clogs, bubbles, tangles, warping and stringing. Treat those as manufacturer claims; the sister bundle below uses the same product name but says ten times stronger, and the listings do not explain the difference. More concrete are the specs: dimensional accuracy of +/- 0.02mm, neatly wound spools, a recommended nozzle temperature of 210 to 235°C and a bed temperature of 55 to 65°C. The spool is 8 inches in diameter, 2.5 inches wide, with a 2.2-inch hub hole. If Oak is the color you care about most, our SUNLU oak PLA guide covers it in more detail.

This bundle suits makers who print a lot and want variety in warm and pastel shades. It gives way to the other PLA+ bundle if you need black, white or grey, since none of those are in this set.

• Ten 1kg spools, 10 kg total
• 1.75mm with +/- 0.02mm accuracy
• Nozzle 210-235°C, bed 55-65°C

The SUNLU PLA Plus 3D Printer Filament bundle in this color set also contains ten 1kg spools of 1.75mm PLA+, but in Black, White, Grey, Blue, Green, Orange, Red, Pure Yellow, Grass Green and Blue Grey. For cosplay builders, black, white and grey are the colors used most often: grey primes well, black suits armor and hardware, and white is a clean base for painted details.

Its listing describes the same core specs as the first bundle: +/- 0.02mm dimensional accuracy, neatly wound spools, an 8-inch spool with a 2.5-inch width and 2.2-inch hub, and recommended temperatures of 210 to 235°C for the nozzle and 55 to 65°C for the bed. The strength claim here is ten times stronger than PLA, which conflicts with the three times figure on the other bundle; the listings do not say whether the formula differs, so we would not choose between them on that number.

This is the pick for a working prop shop that burns through neutral colors. If you print mostly decorative pieces rather than wearable parts, one of the silk options will give a more striking finish.

Display figures with color-shifting shine

The SUNLU 4KG Triple Color Silk Filament pack contains four 1kg spools of 1.75mm silk PLA+, each blending three colors: blue-green-purple, orange-blue-green, red-yellow-blue and red-yellow-green. The listing says prints show different colors from different angles, which is the effect that makes dragon scales, crystal props and character busts look alive on a shelf.

SUNLU claims toughness 50 times higher than standard PLA, describing it as flexible without breaking and impact resistant. The silk texture is meant to look glossy without polishing. The listing also highlights storage: sturdy boxes, reusable vacuum bags and desiccants to keep moisture out. The recommended nozzle range is narrower than the PLA+ bundles at 205 to 215°C, with a bed at 50 to 65°C, so dial in your profile before a long print.

This pack suits figure and statue printers who want show pieces rather than functional parts. If you only need one color-changing spool, the Silk Rainbow below is a smaller commitment.

• Four 1kg triple-color silk spools
• Reusable vacuum storage bags with desiccants
• Nozzle 205-215°C, bed 50-65°C
• +/- 0.02mm diameter accuracy

Best for
Single-spool rainbow prints and gifts

The SUNLU Silk Rainbow PLA Filament is a single 1kg spool, about 330 meters of 1.75mm filament in a Pink-Yellow-Blue-Green mix. Instead of blending colors side by side like the triple color silk, it cycles through them, changing color every 8 meters, so a tall print shows bands of color from bottom to top.

The listing notes that the starting color on each roll can differ from the product image, though the overall mix stays the same. Recommended settings are a nozzle temperature of 205 to 235°C, bed at 50 to 60°C and print speeds of 50 to 200mm/s, with a tip that higher temperatures and slower speeds give a glossier finish. The spool itself is smaller than the PLA+ bundles: 195mm in diameter, 57mm wide, with a 63mm hub hole. It is vacuum sealed and the warranty description reads 30-Day.

It suits makers who want a single eye-catching spool for vases, game tokens or gifts. For functional parts that get worn or dropped, go back to PLA+.
