A 3D printer works by forming materials from computer designs that are fed into it. The most common 3D printers pour melted plastic from nozzles that carefully layer the material, building an object from the ground up. Other than plastic, devices can print using composite powders, resins, metals, carbon fibre and more.
But how can this new technology help your business you may be asking? Prototyping and low-volume manufacturing plays an essential role in the lives of many entrepreneurs and small business owners. As technology continues to improve, new methods of manufacturing continue to emerge as viable methods for small and mid-scale production. Among these is 3D printing, and its widespread use in manufacturing has grown in recent years.
Benefits of 3D printing for small businesses
The benefits of 3D printing for small businesses are significant across a number of aspects. These advantages are just the beginning of 3D printing’s future.
- Using fewer resources. A 3D printer uses the exact amount of material needed to create an object. Traditional machining cuts away material to create a part, wasting material with each part manufactured.
- Customisable products. You can create single objects to fit specific customer needs.
- Save time and cut start-up costs. Cycles of prototyping eat up time and money. The prototypes that don’t work are useless. One of the most promising 3D printing business uses is rapidly developing models and options for testing.
- Simplify production processes. Traditional manufacturing is often a multi-step process that uses lots of machines and devices. With 3D printing, one machine can do it all.
- Streamline repairs. Imagine how much downtime you could eliminate if you could print spare parts when breakdowns happen.
- Limit your outsourcing needs. The ability to use 3D printing across all of these applications makes your business more self-sufficient. When you can eliminate outsourcing business processes, your company can retain more revenue.
Which type of 3D Printing is best for my business?
There are five main types of 3D printing, and you should figure out which type your business will benefit most from.
Stereolithography, also often referred to as SLA, is the most widely used resin 3D printing technology. It is generally considered to provide the greatest accuracy and best surface finish of any prototyping or 3D printing process. SLA is an industrial 3D printing process used to create concept models, complex and intricate parts. It is a popular choice as many parts can be built in just one day.
Also known by its abbreviated term FDM, fused deposition modelling is where the part is built by selectively depositing melted material in a pre-determined path, layer-by-layer. The materials used are thermoplastic polymers and come in a filament form.
When using a SLS 3D printer, a thin layer of material powder is applied on top of the building platform, which is inside a hot chamber with the temperature just under the material’s sintering point. A powerful laser beam “draws” a 2D section of your part on the material surface then with an increase in the temperature above the sintering temperature, the laser sinters the powder particles together, and where necessary to the layer beneath too.
Coloured 3D printing (PolyJet) is one of the latest processes to hit the industrial 3D Printing and general engineering markets and is increasingly popular in the dental, medical and retail industries. PolyJet technology is continually evolving and is known for its realism as well as its sharp precision and ultra-fine detailing. It gives you the ability to create 3D colour-printed parts with the gradients, textures, transparency or opacity your components required.
