Drop on Demand 3D printing is a type of 3D printing process where droplets are deposited on a build plate. The process utilizes wax droplets that cure if exposed to excess light. This process enables materials to be printed in the same object. Without further ado, let’s discuss Drop on Demand 3D printing in this article.
Drop on Demand Thermal Inkjet Printing
Drop on Demand printing uses a unique labeling system designed to inject droplets into a substrate. This technology produces an image using the highly regarded heat-induced explosion of ink bubbles. The most common inkjet printers are bubble jet printers and thermal inkjets.
How Does Drop on Demand Inkjet Printing Work?
In this type of 3D printing, the ink is heated until it completely evaporates. After it evaporates, the ink bubbles will expand which will lead to drops of the ink on the printing surface. Remember that each nozzle in 3D printing is controlled individually. This means that if one nozzle fails it will not affect other nozzles.
Advantages of Drop on Demand 3D Printing
Drop on Demand has many advantages.
Drop on Demand printers are preferred because they print over the surface of an object. Therefore, labels on the item will become unnecessary. Here are other advantages associated with Drop on Demand 3D printing.
- Large character printing. Keep in mind that Drop on Demand 3D printer has large nozzles. The large diameter inkjets can print large-size fonts.
- High printing quality. With inkjet printing, the printed image will be clean and legible.
- It is compatible with special links. It is good to know that inkjet printers work efficiently with special links. Therefore, users can use Drop on Demand inkjet printers to print different colors on cardboard and plastic materials. Besides, it guarantees high quality printing.
- Low cost. As we said earlier, inkjet printers can be used over an item. That being said, the cost of making labels is eliminated.
What’s the Difference between Drop on Demand Inkjet Printer and Traditional Printers?
Drop on Demand Inkjet printers can print on the surface of an item while traditional label printers are used to make labels which must be later applied to the surface of the item.
It is no secret that Drop on Demand inkjet printers will significantly reduce the cost associated with marking. The best thing about Drop on Demand printers is that it does not need the application of labels. Traditional printers, on the other hand, involve processes carried out at once.
Drop on Demand Thermal Inkjet Technology
Unlike other printers, thermal inkjets work with heat. Print heads in thermal inkjet technology feature tiny chambers with controllable heating elements. The heating elements can be cooled in a short time. When the elements are heated, bubbles are created which will lead to overpressure.
The droplets will flow through the cartridge, which will form a printed image on the surface of the object. Bubbles will contract when the elements cool down. Pressure will make ink flow from the cartridge into the chamber.
Piezo Inkjet Technology
This kind of inkjet technology generates pressure using electrical voltage. When the electrical voltage is applied, the electric material deforms. The chamber will experience overpressure when the material bulges. The same thing will happen if the voltage on the inkjet is reversed. As a result of negative pressure, new ink flows from the cartridge into the chamber.
Is Thermal Inkjet Better Than Inkjet?
Thermal inkjets boast less maintenance. In addition, they are made with few moving parts. Another crucial thing to note about thermal inkjets is that they last longer. Finally, thermal inkjets are reliable when compared to inkjet printers.
There is no doubt that Drop on Demand 3D printing is the fastest-growing inkjet technology in the world. Fluid is removed from the jet nozzle in Drop on Demand technology. The unique printing method work through transient pressure. Droplets from the print head are removed when required.
The Types Of 3D Printing
- Stereolithography (SLA)
- Selective Laser Sintering (SLS): (check out the best SLS 3D printers)
- Digital Light Processing (DLP)
- PolyJet 3D printing
- Multi Jet Fusion (MJF)
- Electron Beam Melting (EBM)
- Direct Metal Laser Sintering (DMLS)
- Binder Jetting (BJ) Technology
- Drop on Demand (DOD)
- Fused Deposition Modelling (FDM)
What is Drop on Demand (DOD) 3D printing? It’s a printing technology that allows you to create three-dimensional objects from a digital file.
DOD 3D printers work by depositing small droplets of molten material onto a build platform, layer by layer, until the object is complete.
This type of Printing is becoming more popular because it offers a number of advantages over traditional manufacturing methods. for example, DOD 3D printing can be used to create customized products or prototypes quickly and easily. In this blog post, we’ll take a closer look at how DOD 3D printing works and some of the benefits it offers.
