Laser Toner Powder Manufacturing Process

Groundup sand wax or silica hold the combination of the big three together in the toner.

Laser toner powder manufacturing process. Silica ground to a fine powdery consistency is sometimes added to prevent the toner solution from clumping. Toner is a powder mixture used in laser printers and photocopiers to form the printed text and images on the paper in general through a toner cartridge. Selective laser sintering sls is an additive manufacturing am technique that uses a laseras the power source to sinterpowdered material typically nylonor polyamide aiming the laser automaticallyat points in space defined by a 3d model binding the material together to create a solid structure. Heat sensitive plastic powder particles account for the majority about 60 percent of toner powder s composition.

How a color laser printer works inside an hp 2600 toner cartridge duration. The differences between sls and other powder bed fusion techniques are based on the material options and powder fusing mechanism. Selective laser sintering sls was the first process in the powder bed fusion class developed and commercialised. Complex physical events take place during the manufacturing process and.

Like the plastic wax helps to distribute the copier s toner powder across sheets of paper as it melts. Laser powder based directed energy deposition ded is a specific additive manufacturing process that offers an effective way to fabricate parts via simultaneous delivery of powders and laser beam. It has been developing greatly in the recent decades and being widely used for manufacturing prototyping and repairing. Toner using plant derived plastic also exists as an alternative to petroleum plastic.

Using toner powder with minc machine duration. Toner particles are melted by the heat of the. Mostly granulated plastic early mixtures only added carbon powder and iron oxide however mixtures have since been developed containing polypropylene fumed silica and various minerals for triboelectrification. Wax is melted during the printing process to distribute the toner powder on the paper similar to what the plastic does while silica is sometimes added to the toner to stop the powder from clumping up together when it is packed in the toner cartridge.

It is 10 times faster than the current powder bed process and machining can be completed without a process chamber works with most materials. Very small amounts of ground sand and wax hold together the combination of pigment plastic and iron oxide in toner powder. Small amounts of plastic melt during the laser printing process allowing the toner to adhere to the paper and create an image. Like slm sls is another laser based powder bed fusion technique.
