Being around for more than 30 years, 3D printing has come a long way from research and lab-focused machines to household items and readily available tools in your garage.
The fast pace of development allows people today not only to use 3D printers as a helpful tool for their hobbies, but to establish new businesses and manufacture high-quality products faster and at less cost than ever before.
So, what really changes when the industrial factor comes into play? What distinguishes industrial 3D printers from their consumer counterparts? How can you be sure that a particular 3D printing solution would benefit your business? Let’s figure it out!
There are several issues worth considering before you pick up an industrial 3D printer. So what you basically need is to print a lot at less cost, print large, precise and fast, and print in industrial-grade materials with minimum downtime.
Not long ago the main technology for making plastic parts was injection molding. The appearance and development of additive manufacturing made rapid prototyping and low to medium-batch production accessible to a variety of industries. But what if your design is ready but the production costs are limited by the budget? Can 3D printing become a silver lining which allows for cost savings thus letting you keep under budget? In short, yes!
With x, the upfront cost should be taken into consideration, which is the cost of the mold, that is usually no less than a few thousand dollars. Besides, it takes pretty much time to cut the mold, while with 3D printing you can start production as soon as your design is ready without any advance payments. The cost per part is generally higher with 3D printing, but if the volume you’re going to print doesn’t exceed a few thousand pieces, it is more cost-effective than injection molding, considering the cost of the mold.
Another important advantage of 3D printing compared to injection molding is the R&D freedom allowing for design changes at no additional cost (while each part’s design would require a new mold with conventional technology).
One of the prominent characteristics of industrial 3D printers is that they normally have more spacious build volumes compared to consumer devices. This comes in handy as you can print large objects or multiple smaller parts in one go, thus saving your time and money. Some large-format industrial machines boast enormous build volumes of 1 x 1 x 1 m and more.
Among other features that distinguish industrial 3D printers are high-quality hardware and cutting-edge technologies that ensure decent print speed along with consistent high-resolution printing with predictable results. Industrial machines manufacturers usually offer dedicated slicing software and a range of proprietary consumables to provide the best print quality possible.
The choice of materials used for 3D printing is determined by the technology your device is based on. FDM printers use spools of plastic filaments, while SLA involves liquid resins. The material used with SLS-based printers is polymer powder sintered by a laser. All these materials are utilized both in consumer and industrial 3D printing, the difference lying in the variety of materials supported by the printer. Entry-level models basically print with a few most common types that don’t require special equipment, and that is usually enough for most consumer projects.
