FDM 3D Printing or Fused Deposition Modeling, is an additive manufacturing process that utilizes the material extrusion device to fuse materials to a molten state which is easy to reshape. Actually, in FDM a creation is built by depositing melted material in a pre-setted path layer by layer. The materials used are thermoplastic polymers in a filament form.
To reach a successful printing by FDM, two key processes should be paid attention to:1. Make sure the filament is well melted in the nozzle; 2. Get the material well stuck on the hotbed. If the latter is determined, for the most part, by printing experience, then the former is our engineers’ devout development which guarantees the material well cooled down in other places and melted in the heat block.
Then how wisely Kywoo nozzle kit is designed?
One thing we need to clarify first is that the material must be melted just right in the nozzle or the filament would be stuck in the channel which would lead to failure or even cause damage to the kit. So one funny thing for us to know is that though we use FDM technology to get the material a fusion, the more crucial problem we need to solve is actually cooling.

The red part is our extrusion and heat dissipation two-in-one patent which optimizes the cooling system. With the two fans’ co-working, our extrusion and heat dissipation two-in-one patent’s premium heat absorption and conduction capacity can guarantee the filament in a solid condition without any distortion or melting before it penetrates through the PTFE tube. Imagine this, what if the filament melted in the channel above the nozzle? The material is easy to cool down, so the melt would be stuck and jeopardize the extrusion system.
3D Printer Structure
Now you are familiar with the fused deposition modeling or FDM. They are also sometimes referred to as fused filament fabrication or FFF. 
The way it usually works is that a spool of filament is loaded into the 3D printer and fed through to a printer nozzle in the extrusion head. The printer nozzle is heated to the desired temperature, whereupon a motor pushes the filament through the heated nozzle, causing it to melt.
The printer then moves the extrusion head along with specified coordinates, laying down the molten material onto the build plate, where it cools down and solidifies. Once a layer is complete, the printer proceeds to lay down another layer. This process of printing cross-sections is repeated, building layer-upon-layer until the object is fully formed.
To make sure a stable printing, Kywoo’s team got a breakthrough on appearance at a mechanical engineering level.

Different from a single gantry design, Kywoo’s double gantry can guarantee a stable printing that avoids unexpected interference. Also, you can notice that two rods are designed beside the screw rods to provide a double guarantee of the vertical state of the z-axis. Linear rail in x-axis make it work quietly and less machine wear. These features are pros compared to other brands, but what appeals to me most is its flexibility. Kywoo’s machine provides boundless possibilities for users to DIY, Kywoo Tycoon printers can be escalated by your will and needs.
