  • In order to choose the method of 3D printing that is most suited to your application, it is necessary to have a solid understanding of the advantages and disadvantages associated with each of the available options. It is possible to achieve this goal by mapping the features of each process to the requirements you have set for product development. To begin, let's discuss the role that 3D printing plays in the larger context of the product development cycle. Next, we'll take a look at the various approaches to 3D printing that are currently in use as well as the advantages that come along with each one.

    It is reasonable to assume that prototyping is the most typical use for three-dimensional printing. Because the company is able to quickly manufacture a single part, product developers are able to validate their ideas in a way that is both quick and cost-effective thanks to the company's ability to manufacture a single part so quickly. Before you can decide which type of 3D printing technology will be most useful for your prototype, you will first need to establish what the purpose of the prototype will be. Additive manufacturing has the potential to be useful for a wide variety of prototypes, ranging from simple physical models to components that are put through functional testing. This broad range of prototypes could benefit from the use of additive manufacturing.

    In spite of the fact that the terms "rapid prototyping" and "3D printing" are almost always used synonymously with one another, there are some instances in which the latter can be an effective method of manufacturing. The majority of the time, these applications are concerned with relatively low volumes and complex geometries. Components used in aerospace and medical applications frequently meet the requirements for production 3D printing, making them ideal candidates for the process. This makes 3D printing an attractive option for fabricating these components. This is as a result of the fact that they frequently satisfy the criteria outlined in the earlier paragraph.

    Let's talk about the circumstances in which each of the more common processes for 3d plastic printing services with plastic offers the most benefit to product developers, engineers, and designers. We'll start by going over some of the more common processes for 3d printing with plastic.

    Stereolithography, also known as SLA, was the technique that was initially utilized for the purpose of industrial 3D printing. SLA printers are most effective when used for the production of parts that require high levels of detail, smooth surface finishes, and close tolerances. Surface finishes of high quality on SLA parts not only make the parts look nicer, but they can also help with the function of the part, such as testing the fit of an assembly. This is one example of how surface finishes can contribute to the functionality of the part. Two examples of common applications in the medical industry, which makes extensive use of the material, are anatomical models and microfluidics. Both of these fields make extensive use of the material. We use 3D printers manufactured by 3D Systems, specifically the Vipers, ProJets, and iPros models of their 3D printers, in order to print SLA parts.

    The process of selective laser sintering, more commonly abbreviated as SLS, is one that solidifies nylon-based powders into a plastic material. Because the actual thermoplastic material is used in the fabrication of SLS parts, those parts have a long lifespan, are suitable for functional testing, and are able to support living hinges and snap-fits. Additionally, SLS parts can be customized to fit specific requirements. In comparison to SL, the surface finish of the components is more uneven, but they are noticeably more durable as a result. Because SLS does not require support structures, the entire build platform can be used to nest multiple parts into a single build. This is possible because SLS does not require support structures. As a result of this, it is appropriate for use with higher part quantities than those produced by other Online 3D Printing  processes. In the process of prototyping designs that will ultimately be injection-molded, a significant number of parts created with selective laser sintering (SLS) are used. For our selective laser sintering (SLS) printers, we make use of 3D systems' sPro140 machines, which they developed.

    When compared to other techniques for custom 3D printing with plastic, PolyJet stands out as having a number of distinctive advantages. It is able to fabricate parts with multiple properties, such as colors and materials, and it can also change the properties of the parts that it has already created. Prototyping elastomeric or overmolded components can be accomplished with the help of this technology, which can be utilized by designers. We recommend sticking with SL or SLS because it is the more cost-effective option if your design only requires a single piece of rigid plastic. This is because SL and SLS are both known as stereolithography. If, on the other hand, you are prototyping a design that incorporates overmolding or silicone rubber, you can use PolyJet to avoid having to make an investment in tooling during the early stages of the process of developing the product. You will be able to save both time and money as a result of this, and the process of validating and iterating your design will move along much more quickly.

    The process of curing liquid resin with the use of light is at the core of both stereolithography (SLA) and digital light processing (DLP). The primary difference between the two technologies is that DLP makes use of a digital light projector screen, whereas SLA makes use of a UV laser in its manufacturing process. DLP 3D printers are able to image an entire layer of the build at once, which enables them to produce significantly faster build speeds than other types of 3D printers. In spite of the fact that this printing method is most commonly utilized for rapid prototyping, it is possible to use DLP printing for low-volume production runs of plastic parts due to the higher throughput that this printing method offers.

    Similar to SLS, the additive manufacturing technique known as Multi Jet Fusion uses nylon powder as the primary building material to create functional parts. In order to achieve the desired result of sintering the powder, MJF utilizes an inkjet array rather than a laser in order to apply fusing agents to the bed of nylon powder in order to achieve the desired result. A heating element that is moved over the bed is used to finally melt the layers together into one cohesive mass. In comparison to SLS, this results in more consistent mechanical properties, and it also improves the surface finish. Additionally, it leads to an overall smoother appearance. The MJF process has a number of benefits, one of which is that it cuts down on the amount of time needed to construct something, which in turn leads to lower production costs.

    Fused deposition modeling, also known as FDM for short, is a type of desktop  technology that is frequently used for the production of plastic components. An FDM printer achieves its purpose by layer-by-layer extruding a plastic filament onto the build platform. This process is known as "fused deposition modeling."Utilizing this method enables the production of physical models to be carried out rapidly and at a reduced cost. Functional testing can be done with FDM in certain situations; however, the technology is limited because the parts it produces have surface finishes that are relatively rough and lack the required strength. Functional testing can be done with FDM in certain situations.
