Description

PolySonic™ PLA is a revolutionary high-speed 3D printing filament, the ultimate game-changer in additive manufacturing. With its lightning-fast extrusion rate, cutting-edge precision, and exceptional layer adhesion you can ramp up the speed of your 3D printer and witness new levels of productivity. Accelerate your workflow without compromising on strength or quality.

A material is considered "High Speed" if it fulfills the following 3 criteria at a set printing temperature:

1) Flowability: It can extrude consistently at 24mm3/s on popular extrusion system. (equivalent to 300mm/s at 0.2mm layer height with a 0.4mm nozzle)

2) Formability: At 24mm3/s, it maintains similar surface quality, overhang and bridging as printed at lower speed.

3) Functionality: At 24mm3/s, it maintains at least 80% of its overall mechanical properties when printing at lower speed. (mainly: layer adhesion, tensile strength and impact strength)

PolySonic™ PLA at 230˚C
1) Maximum flow*: 29mm3/s** (tested on a customized extrusion platform equipped with an E3D volcano hotend, 0.4mm nozzle with Hemera XS extruder)

2) Confirmed similar quality Polymaker Scientist when printed at 4mm3/s and 24mm3/s

3) Layer Adhesion at 4mm3/s-24mm3/s: 37.3-32.3 MPa (Maintain 87%)
Tensile Strength at 4mm3/s-24mm3/s: 46.0-43.9 (Maintain 95%)
Impact strength at 4mm3/s-24mm3/s: 6.1-5 kJ/m2 (Maintain 82%)

* Maximum Flow: Flow at which the measured flow is decreasing below 95% of the requested flow.
**
For 0.2mm layer height with 0.4mm nozzle: 29mm3/s -> 363mm/s
For 0.1mm layer height with 0.4mm nozzle: 29mm3/s -> 725mm/s

What are the advantages of using a High Speed filament? 

1) Surface Quality at high speed:

When printing at high speed, the nozzle will actually experience a wide variety of speed going from 0mm/s to the max speed set on the slicer. The higher the max speed, the wider the range of different speeds. The issue is with the printing temperature being the same, the extrusion temperature will vary dramatically leaving difference surface finishes on the print (from glossy to matte because of a phenomenon called: Shark Skin), High Speed filament reduces these differences by displaying similar surface finish in a wide range of flow rates.
Additionally, high speed filament will extrude much more consistently within the speed range providing a smooth surface whereas regular filament will display holes, artifacts and layers with different thicknesses.

2) Mechanical Properties at high speed: 

High Speed filament will display far greater overall mechanical properties when printed at higher speed than regular filament because of the more consistent extrusion and the optimized cooling/melting rate of the polymer.

3) Higher Throughput:

Thanks to 1) and 2), you are able to output the same quality part at a much higher pace from your 3D printer. This advantage is ideal for businesses using 3D printing to produce their products.

Love the look but runs narrow
Size: 7 Toddler, Color: Navy, Size: 7 Toddler, Color: Navy
Obsessed with the navy, it literally goes with everything. Quality is great too, really happy with how they’re made. Super cute too. Only thing is my son has wide feet and they ran a little tight on him. If your toddler is on the wider side, might be worth sizing up. Overall still happy with them!

Snug fit with ease of putting on
Size: 7 Toddler, Color: Navy, Size: 7 Toddler, Color: Navy
These Amazon Essentials hook-and-loop athletic sneakers have been a fantastic everyday shoe for toddlers and little kids. The fit and comfort really stand out. The padded collar and cushioned insole make them comfortable enough for all-day wear, whether that’s running around at school, playing at the park, or just being on the move at home. One of the biggest wins is how easy they are for kids to put on themselves. The hook-and-loop closure combined with the faux elastic laces strikes a great balance between a secure fit and independence, which is a huge plus for busy mornings. They stay snug without being tight and don’t slip off during active play. The materials feel well made for a kid’s sneaker. The faux leather and mesh upper looks sporty and holds up well to daily wear, while the mesh lining helps with breathability. The TPR sole provides good traction and stability, giving a solid, supportive feel without being stiff or heavy. Style-wise, these shoes are versatile and cute. The athletic look with subtle vintage-inspired details works with everything from play clothes to more put-together casual outfits. Overall, these sneakers deliver comfort, durability, and kid-friendly design at a great value. A reliable, no-fuss choice for active little feet.

Slim toes and runs small.
Size: 11 Little Kid, Color: Metallic Gold
These sneakers ran small and are very slim down the foot. Definintely not wide friendly or even toe box friendly for those who want more friendly 'barefoot' shoes. The colors are cute. Easy to put on and off, especially for toddlers with the lack of laces. Just not a great sneaker for those who want something that will last longer and not pinch toes or create ingrowns.
