What is 3D Printing? Future Of Manufacturing Industry !!

What is 3D printing?

3D printing is an innovative technology that lets you create a physical object from a digital model. All you need to do is make a design, transfer the file to a 3D printer, then bring your object to life.

 In its simplest terms, it’s a form of additive manufacturing (material is added, not removed).

This is how it works, step by step.

1. Create a digital design: The first stage is to create a digital model in a 3D modeling program (CAD – Computer Aided Design) or by using a 3D scanner.

2. Import: Next, import the design to 3D printing software, such as Ultimaker Cura. This free and open-source software slices the digital model into layers, and converts these into a G-code file, which can be ‘read’ by the 3D printer.

3. Save / transfer: The Ultimaker Cura file is saved to a USB, which is inserted into your machine. Alternatively, the file can be saved to the cloud, then sent to the printer.

4. 3D print: The final step is to press print. The printers produce layers of material, one on top of the other. This forms the finished object. Desktop printers usually use plastic filaments, which are fed in, then melted in the print head. This liquid substance is extruded onto the build plate.

The 3D printing process starts with a digital model which is then prepared for 3D printing (or 'sliced')

3D printing is a form of 'additive manufacturing' as layers of material are extruded and build up a model

What is 3D printing used for?

3D prints can be used in several different ways, across many different industries. These are just a few examples.

Explaining complex concepts

Industries where 3D printing is most used

The industries where 3D printing is most used are automotive, aerospace, consumer goods, industrial goods, medical, and education.

The main business benefits include being able to:

·         Create custom models

·         Rapidly create prototypes

·         Design 3D models with complex geometry

·         Reduce costs and speed up key processes

·         Make tooling for manufacturing

·         Print end-use parts

Different 3D printing materials

Ultimaker has a wide range of filaments, all suited to specific tasks

Examples of 3D printing filament include:

Polylactic acid (PLA)

This biodegradable polymer has a good surface quality. It’s ideal for concept models and visualization aids.

Co-polyester (CPE)

CPE is chemical-resistant, with a high tensile strength. As such, it’s great for mechanical applications. It’s also odorless, which makes it one of the safest choices for printing. CPE+ is stronger, and suitable for functional prototyping.

Polycarbonate (PC)

Polycarbonate is super-tough, making it ideal for engineers. It’s also heat-resistant.

Nylon (polyamide)

Nylon is flexible and strong, so it’s good for printing tools and end-use parts. It’s also abrasion-resistant.

Polypropylene (PP)

This is the second-most commonly used polymer, and is tough and low-friction. It’s also semi-flexible.

Thermoplastic polyurethane (TPU 95A)

This semi-flexible material performs similarly to rubber, and can withstand impact without breaking or deforming.

Polyvinyl alcohol (PVA)

PVA isn’t used for the finished printed product. Instead, it’s a removable support structure that dissolves in water. Useful in the 3D printing process for creating features like overhangs.
