3D printing service for custom parts

3D printing, also known as additive manufacturing, is a process of creating objects by building them layer by layer using digital 3D models as a blueprint. The process starts with a digital design file, which is sliced into thin cross-sectional layers. These layers are then sequentially printed, typically using materials such as plastics, resins, metals, or ceramics, to gradually build the final three-dimensional object. 3D printing offers numerous advantages, including the ability to create complex geometries, rapid prototyping, customization, reduced material waste, and on-demand manufacturing. 

Prototyping, on the other hand, refers to the creation of a preliminary or scaled-down version of a product or part before proceeding to full-scale production. 3D printing is often used as a preferred method for rapid prototyping due to its ability to quickly produce physical prototypes directly from digital models.

By combining 3D printing technology with prototyping, product designers and engineers can create tangible and functional prototypes that closely resemble the final product. This enables early testing, validation, and iteration of the design, leading to more efficient and cost-effective product development processes. 

3D printing and prototyping have become invaluable tools in various industries including manufacturing, healthcare, automotive, aerospace, product design, consumer goods and more. Its capabilities allow for the creation of complex designs that would be challenging or impossible to achieve with traditional manufacturing methods. Furthermore, 3D printing often offers a more cost-effective solution, particularly for small production runs.

3D printing starts with a digital design, usually created in a Computer Aided Design (CAD) program or scanned into the computer using a 3D scanner. The design is then converted into a format that the 3D printer can understand. There are several different types of 3D printing technologies. Here are some of the most common types: 

1. Fused Deposition Modeling (FDM): Also known as Fused Filament Fabrication or FFF, FDM is one of the most widely used 3D printing technologies. It works by melting and extruding a filament of thermoplastic material, which is then deposited layer by layer to create the 3D object.
2. Stereolithography (SLA): SLA is a process in which a computer-controlled laser beam is used to build up the required structure, layer by layer, from a liquid polymer that hardens on contact with laser light, creating the desired 3D object.
3. Selective Laser Sintering (SLS): SLS is a rapid prototyping process that utilises a high-powered laser to selectively sinter or fuse powdered materials, such as plastics or metals, layer by layer, to create the desired product.
4. Direct Metal Laser Sintering (DMLS): DMLS uses a high-powered laser that is directed onto a metal powder bed, fusing metal particles based on a computer-aided design or CAD file. The process selectively fuses the metal powder together, layer by layer, resulting in the creation of metal objects with exceptional precision and intricate complexity.
5. Digital Light Processing (DLP): DLP is another 3-D printing technology that is based on photo curing. It is similar to SLA but uses a different light source, typically a digital projector, to cure the liquid resin. It exposes an entire layer at once, resulting in faster printing times compared to SLA.
6. Binder Jetting: Binder jetting involves a process in which an industrial printhead selectively deposits a liquid binding agent onto a thin layer of powder particles — such as foundry sand, ceramics, metal or composites — to build high-value and one-of-a-kind parts and tooling.
7. PolyJet: Polyjet is a unique 3D printing technique that uses liquid photopolymers, similar to an inkjet printer. PolyJet technology works by jetting photopolymer materials in tiny droplets onto a build tray. These droplets are instantly cured using UV light, allowing for precision as fine as 0.1mm. With Polyjet, you can produce prototypes with complex geometries and mix different materials in a single print run. It also offers a wide range of colours and material combinations, resulting in highly realistic prototypes.

These are just a few examples of 3D printing technologies, each with its own advantages, materials compatibility, and applications. The selection of the appropriate technology depends on the specific requirements of the project, including desired materials, level of detail, and production volume.

Design freedom: 3D printing allows for the creation of complex geometries and intricate designs that are difficult or impossible to achieve with traditional manufacturing methods. It offers design freedom without the limitations of traditional tooling or machining processes such as injection moulding, casting or machining.

‍

Rapid production: 3D printing allows for rapid production of parts compared to traditional manufacturing methods. The process of 3D printing is typically faster as it eliminates the need for complex setups, moulds, or tooling. This speed advantage is particularly beneficial for rapid prototyping, small-scale production, or on-demand manufacturing where quick turnaround times are essential. 3D printing can often produce parts within hours or days, depending on the complexity and size of the object, making it a valuable solution for time-sensitive projects or applications.

Rapid prototyping: 3D printing enables the quick creation of prototypes directly from digital models, significantly reducing the time between the initial design stage and the prototype stage. This rapid prototyping capability allows for faster iterations, design validation, and product development cycles.

Cost-efficiency: In traditional manufacturing methods such as injection moulding or casting, significant upfront costs are incurred to create the moulds or tooling required for production. However, in 3D printing, there is no need for expensive tooling or moulds as the digital design is directly translated into the physical object without the need for tooling. This reduces the financial barrier to entry and makes it more accessible and cost-effective, particularly for small-scale production or custom parts. It also allows for quicker iterations and changes to the design without incurring additional tooling costs, providing greater flexibility.

Customization: Each 3D printed part can be easily customised without additional manufacturing processes or costs. This makes it ideal for producing personalised products, one-off designs, or medical applications where customization is crucial.

Waste reduction: 3D printing is an additive manufacturing process, which means it only uses the necessary amount of material required for the object being printed. This reduces material waste compared to traditional subtractive manufacturing methods, where excess material is typically removed and discarded.

Complexity and integration: 3D printing enables the creation of parts with intricate internal structures, integrated features, and consolidated multi-component assemblies. It allows for the production of complex, lightweight, and optimised designs with improved functionality.

Enhanced thermal management and fluid dynamics: 3D printing can create intricate internal structures within a printed object that enhance heat transfer and fluid flow capabilities. With traditional manufacturing methods, it can be challenging to create complex internal geometries or channels within a part. However, 3D printing allows for the design and production of intricate internal features, such as intricate cooling channels, heat sinks, or fluid flow paths, that optimise thermal management and fluid dynamics within a component. Examples include heat exchangers, aerospace components, electronics cooling systems, and medical devices where efficient heat transfer or fluid flow is crucial.

On-demand manufacturing: With 3D printing, parts can be produced on-demand, eliminating the need for large inventories or long lead times. This offers flexibility in manufacturing and reduces storage and inventory costs.

The cost of 3D printing can vary depending on several factors. The price is influenced by the complexity of the design, the size of the object to be printed, the material used, and the 3D printing technology employed. Additionally, the quantity of items to be printed, the desired level of detail, and requirement for any post-print operations can also influence the cost. Post-print operations refer to the additional steps or processes that are performed on a 3D printed object to refine, finish, or enhance the final appearance, functionality, or characteristics of the printed part after it has been removed from the 3D printer.

All these factors are why it is essential to consider the specific requirements of your project when estimating the cost of 3D printing.

Using 3D printing to print prototypes or parts has several advantages. These include rapid prototyping, cost effectiveness (especially for small volumes), design flexibility (because it enables the creation of complex geometries), on-demand manufacturing and so on. This is the reason it is used across industries such as aerospace, automotive, healthcare, consumer goods, and more.

For 3D printing, it is typically required to provide a 3D model file in a specific format. The formats Step (.stp/.step), Solidworks (.sldprt), and IGES (.igs/.iges) are highly recommended, even though in most cases, these files are eventually converted to the STL (.stl) format before printing. The reason for recommending Step, Solidworks, or IGES formats is that they are information-rich and capture more detail compared to STL files. These formats retain the complete geometric data, including design structures, assembly information, and other intricate details of the model. This parametric information makes them suitable for design storage, collaboration, and engineering purposes. 

Starting with Step, Solidworks, or IGES files ensures that the original design's integrity is preserved, reducing the risk of data loss or inaccuracies during printing. By uploading your design in one of these formats, you facilitate a smoother transition into the 3D printing workflow, resulting in more accurate printed objects.

In conclusion, while STL remains the standard format for 3D printing, providing your design in Step, Solidworks, or IGES formats offers the advantage of richer information and better data retention, making them preferred choices for preparing 3D models before printing.

The size of a part that can be 3D printed depends on the capabilities of the specific 3D printing technology and equipment used. The maximum printable size can vary significantly between different 3D printers.

Desktop 3D printers have a limited build volume, typically ranging from around 150mm x 150mm x 150mm to 300mm x 300mm x 300mm. These printers are suitable for creating small to medium-sized parts. Industrial 3D printers have much larger build volumes, often exceeding 1000mm x 1000mm x 1000mm or even larger. These printers are capable of producing larger parts, making them suitable for industrial and architectural applications.

At ProtoAnything, we have build volumes of 1000 mm x 1000 mm x 1000 mm but can make bigger parts by assembling smaller prints.
