Metals: Aluminum, stainless steel, and titanium alloys are ideal materials for custom robot parts because they are lightweight but strong, making them ideal for parts that need to withstand heavy use and frequent movement. Copper, brass, and bronze have excellent electrical conductivity, making them ideal for parts that require electrical current or wiring.   Plastics: ABS, polycarbonate (PC) and acrylonitrile  stybutadienerene (ABS) are all highly durable materials that can withstand extreme temperatures and harsh environments, making them suitable for robotic applications. High density polyethylene (HDPE), polypropylene (PP), and nylon offer flexibility while remaining light, which makes them ideal for creating custom robotic parts with complex shapes or complex designs.                

While the use of 3D printing for rapid prototyping has been developing since the late 80s and is now extremely common, the industry has also steadily continued its move towards production applications, including low-volume production, mass customization, and serial production. “We’re seeing more and more large-quantity orders and repeat orders,” says Protolabs’ Robin Brockötter. “There’s definitely a trend towards full-scale production.” This is influenced by many and diverse factors, including a preference for more local production amid global supply-chain disruptions (9% of our survey respondents said low susceptibility to supply chain issues is the main reason why they opted for 3D printing over other manufacturing methods) and sustainability concerns. In 2023, 21% of our survey respondents used 3D printing for end-use parts—up from 20% in 2022—and 4% used it for aesthetic parts. When it comes to replacing injection-molding manufacturing with 3D printing processes, it’s all about order volumes: for low-volume production, 3D printing is often the more cost-effective solution, while at higher volumes, injection molding becomes more economical. However, the point where that happens— the ‘sweet spot’ of maximum viable 3D printing order volume—is shifting. “3D printing can now start producing more and more parts before injection molding becomes cheaper,” says Brockötter. Results from our 2024 survey support this. In our 2023 survey, doubts around 3D printing as a choice for “production volume and scale” led 47% of respondents to opt for different manufacturing technologies, but this year that number has dropped to 45%, showing increased confidence in scaling with 3D printing. And throughout the years, our surveys also show a steady growth in production-run volumes: respondents saying they printed more than 10 parts rose from 36% in 2020, to 49% in 2021 and to 76% in 2022. While this figure has stayed the same for 2023, marking stabilization, the percentage of respondents saying they printed more than 1000 parts rose from 4.7% in 2022 to 6.2% in 2023. Beyond the actual printing process, there are many other aspects that influence the scalability of using 3D printing technologies for production, from software, design, and materials to post-processing and finalizing tasks such as cleaning, secondary finishing, spot removal, stress relief, and inspections. As the 3D printing ecosystem continues to mature, a support system of companies providing many of these services is springing up around 3D printing businesses, simplifying production processes. This in turn will encourage the uptake of these processes. In addition, increasing familiarity with DFAM—the additive design space—will mean engineers and designers will become more proficient at navigating design limitations and opportunities and leveraging new materials. And many obstacles are becoming less of an issue due to new developments and technologies. One example is post-processing, which can currently present a bottleneck. 27% of respondents to the 2024 survey named “post-processing and finishing requirements” as a reason for choosing other manufacturing methods over 3D printing, and 40% listed “quality and consistency of the final product”. However, as vapor smoothing is becoming prevalent across the industry and surface finishes are being radically improved, postprocessing is becoming less of a hurdle for production-level 3D printing. “Vapor smoothing machines have come a long way in recent years,” says Grant Fisher, supply chain manager at Protolabs, “specifically for vapor smoothing Nylon 12”—the most common material for MJF and SLS parts. “We continue to see a lot of growth in MJF and SLS, and vapor smoothing is a great option for aesthetic and end-use parts.” Another example is automation of the manufacturing process. For instance, computer-visionsupported systems to help sort finished 3D printed parts can represent significant labor savings and cost efficiency, further pushing the numbers in favor of 3D printing. Standardization is one key issue that remains, particularly in sectors such as aerospace, automotive and the medical industry. “We do a lot of work with aerospace, particularly in metal printing,” says Protolabs’ Eric Utley, “and the big hurdle that everyone’s dealing with is standardization. Building out that validation and standardization—I personally think it will take a few years to unstick that.” But the will is there and the cogs are moving. “It is a big talking point in the wider industry,” says Utley. The medical and aerospace sectors are the ones where 3D printing for production will continue to play the biggest role, says Alex Huckstepp. “These are the industries that are willing to spend a lot on high-performance, high-quality, complex custom designs and components. And that was always thought of as where 3D printing in production could make sense. The real production growth is still coming from those two industries. The space-race boom that we’re seeing has definitely been a tailwind for 3D printing.” There’s another point that’s often overlooked when discussing production-level 3D printing, sometimes to the detriment of embracing its incredible potential: it shouldn’t necessarily be approached as a replacement for existing technologies at all. “I think a lot of people have in their mind that 3D printing is an injection molding competitor—yeah, it’s not,” says DIVE’s Adam Hecht. “It’s an entirely new way of making things. They just don’t compete. There’s some overlap, yes, but ultimately, their careers separate. 3D printing is an entirely new tool. It’s enabling us to solve problems, and ultimately, to make products that previously couldn’t exist. All the low-volume, specialized applications and products where you previously had to tell people, sorry, we can’t make that—we can make them now. It’s just entirely different.” And one thing that’s going to enable and accelerate this are the specialized materials that are increasingly emerging on the 3D printing market.

What is CNC machining? CNC stands for Computer Numerical Control, so CNC machining can be defined as a manufacturing process where a computational code controls the parameters of the process, including: Movement of the machine tool head. Movement of the part or feed. Rotational speed. Tool selection, for multi-tool heads. Amount of coolant if needed. In simple words, it means using computational power to control and monitor all the necessary movements of a machine to manufacture parts out of raw material. How does CNC machining work? Basically, the CNC program provides commands that the machine can read and understand. These commands tell the motors of the machine when and how to move the corresponding components to achieve the desired results. The first CNC machines used punch cards with the written code and had limited flexibility for the movement of the tool. However, current CNC machines can be associated with CAD/CAM software (Computer Aided Design/Computer Aided Manufacturing). This means that the designer can create a 3D model of the part and then translate the parameters of the part into a CNC program by means of the CAM software. This final program, created by the CAM software, is fed into the machine and the manufacturing process begins. The part is finished when the machine finishes running the program. Another important aspect of the current and the most sophisticated CNC machines is the flexibility they have, since they can move in a range of 2.5 axes, 3 axes or 5 axes depending on the type of machine. CNC machining for woodWhile many might think that wood working is an art for only the most skilled carvers, the truth is that CNC machining for wood allows for a more efficient work. Even for the most complex designs. With CNC machining for wood is possible to produce larger parts in a shorter time. It also allows the woodworker to keep the natural beauty and strength of the wood used intact, something difficult to achieve with other type of machines for processing wood. Other benefits from using CNC machining for wood are: Complex shapes that are too difficult for manual work can be achieved easily. Higher precision and shorter production times. Higher efficiency and reduced material waste. Increased profitability. CNC machining for medical industryIt is well known that the medical industry is a very demanding one with all the standards that must be met. This is the case of CNC machining for medical industry. Fortunately, as it was mentioned above, the main benefits of CNC machining are high efficiency and high accuracy that leave almost no room for error. This makes CNC machining for medical industry the best manufacturing option in the sector, being precision machining the chosen alternative to meet the tight tolerance requirements. Other common requirements include: Complex geometries that usually require 5-axis machines. Very high levels of cleanliness. Possibility of machining different special materials. Top-level surface finish. Common applications of CNC machining for medical industry include: Implants and prosthetics. Surgical instruments. Electronic components for medical equipment. Micro medical devices which require micromachining. CNC machining for castingCasting is a manufacturing process that depends of good molds to obtain desired results. This means that it is necessary to select the best process to produce the molds. CNC machining for casting in 5-axis machines reduces the chance of error due to having to move the casting between machining operations. This error reduction allows for the casting to meet the tightest of tolerances. Another good application of CNC machining for casting is that most castings require a post processing to improve surface finish. CNC machining for casting allows to achieve the surface finish desired in a quick and efficient way. Moreover, CNC machining can deal with the type of materials commonly used for castings such as aluminum, which can be a problem for other manufacturing problems. CNC machining for aluminum Being a lightweight metal, aluminum is the preferred material for many applications, being automotive and aerospace the top users. However, its use in some of these applications requires very complex shapes. Moreover, thin parts may be required, which increases the possibility of deformation due to the low hardness and high thermal expansion of the material. Here’s where CNC machining for aluminum becomes important. 5-axis CNC machining for aluminum provides benefits such as: It is simple to set up, which reduces lead times and improves the efficiency It allows to work with complex geometry thanks to the ability of avoiding collision with the tool holder while tilting the wok table or the cutting tool. It can use shorter tools that are more rigid, some with high spindle speed rates which is achieved by reducing the load on the cutting tool. The parts don’t have to go through different workstations, meaning that the errors are reduced, the accuracy is increased, and the quality is ensured. These machines can use other alternatives such as water jet cutting or laser cutting which eliminate the problems of working with very thin aluminum pieces. CNC machining for aerospace parts With the number of components needed to assemble an aircraft, and the complexity of such components, it is clear that the aerospace industry requires the highest precision and efficiency possible out of a manufacturing process. Therefore, CNC machining for aerospace parts has grown in popularity, and it is now the go-to option for aerospace components manufacturing. CNC machining for aerospace parts needs to deal with complex requirements such as: Working with thin walls. Limiting material deformation, for example, when working with aluminum and other lightweight materials. Working with curved and complex geometries. On the other side, CNC machining is the best option for aerospace parts production as it provides the following benefits: It is a cost-effective process. It can provide high-quality results. It can work with custom designs. It provides high accuracy and precision engineering. It reduces and sometimes eliminates human error. It can produce complex geometries. CNC machining for jewelry In the past, jewels were only made by hand by fine artisans. However, it is not the case anymore, as more and more jewel producers are implementing methods to improve their efficiency and increase their profitability. There are different ways CNC machining for jewelry help artisans and jewel producers in general. The most common benefits found are: Easily create master models for casting the jewels. Quickly create casting molds with high accuracy. Create fine end-use jewels when using sophisticated CNC machines. Quickly and accurately create custom engravings. Easily finishing the jewels with marble faceting and jewel polishing processes. CNC machining tolerances It is true that CNC machining has taken manufacturing accuracy to very high levels. However, as it happens with other manufacturing process, the dimensions of the end product are never perfect. And here is where CNC machining tolerances play an important role. We have to remember that tolerances represent the maximum allowed variation for the same dimensions of two parts from the same series. They are usually set in the design phase. There are different aspects to be considered when setting the tolerances required: Mating components. Type of materials. Manufacturing processes available. Tighter tolerances are usually more expensive to achieve. Tolerances are usually classified according to how tight they are in the following groups: Fine tolerances. Medium tolerances. Coarse tolerances. Very coarse tolerances. In general, the limits for each group are set based on International Standards, including ANSI B4.1, ANSI B4.2, ISO 286, ISO 1829, ISO 2768, EN 20286 and JIS B 0401. For CNC machining tolerances, the standard limits are in the range of ± 0.005″ or 0.13mm. However, some very sophisticated services claim they can provide CNC machining tolerances as tight as ±0.0025mm. Here are some standard CNC machining tolerances depending on the CNC process: Lathe — ±0.005″ (0.13mm) Router — ± 0.005″ (0.13mm) 3-Axis Milling — ± 0.005″ (0.13mm) 5-Axis Milling — ± 0.005″ (0.13mm) Engraving — ± 0.005″ (0.13mm) Flatness — ± 0.010″ (0.25mm)

CNC machining services also play an important role in the consumer goods industry, for example, in the production of high - end electronics and jewelry. he process of CNC machining services generally includes several steps. First, there is the design stage, where the part to be machined is designed using CAD software. Then, the CNC programming is done to convert the design into machine - readable instructions. After that, the setup of the CNC machine is carried out, including loading the proper tools and securing the workpiece. Next, the actual CNC machining services are performed as the machine follows the programmed instructions to cut or shape the material. Finally, quality control is conducted to ensure that the parts produced by CNC machining services meet the required standards.   CNC machining services also require careful consideration of several factors. Material selection is important for CNC machining services. Different materials may require different machining techniques and parameters. Tool selection is another aspect that affects CNC machining services. The right tools need to be chosen based on the material and the type of operation. Cost is also a factor in CNC machining services.

Wondering about CNC machining and why it’s a big deal in the manufacturing world? You’re not alone. Computer Numeric Control (CNC) Machining is a key player in modern manufacturing, using advanced technology to cut, shape, and create parts with precision. This article breaks down the basics of how CNC machines work and their role in making everything from car parts to tech gadgets. We’ll also look at the many industries that rely on this technology and why it’s so important. Overview of CNC Machining CNC machining, controlled by computers, produces high-precision parts and components. In this process, a computer program controls the movement of the cutting tools, which the CNC programming controls to remove material from a workpiece to create a finished part.   CNC technology produces an array of parts and components, including those made from metal, plastic, and other materials. The process can also produce parts with complex geometries and high levels of precision, making it a popular choice for applications in numerous industries, including aerospace, automotive, medical devices, and consumer products. It offers several advantages over traditional machining methods, including improved accuracy, consistency, and speed, as well as the ability to produce complex geometries and intricate details. It also allows for the use of advanced cutting tools and techniques, such as multi-axis machining centers and high-speed machining, which can further improve the efficiency and quality of the process. The History of CNC Machining Its history can be traced back to the 1940s when the first numerical control (NC) machines were developed. Over time, these machines became more widespread and sophisticated. This gave them the capability to fulfill the requirements of a variety of industries including aerospace, automotive, and defense.   However, older CNC machines still needed manual input and had limited capabilities. The transformation of manufacturing began in the 1970s with the introduction of computers, leading to a breakthrough: the first CNC machines. These advanced machines, equipped with computer controls, could process data with unprecedented speed and accuracy. This innovation allowed CNC operators to input commands directly into the machine, which then automatically executed the necessary operations, significantly streamlining the manufacturing process. This was only the beginning of CNC machines as the technology continued to advance over the years. The development of more advanced software and hardware along with the introduction of new material and tooling options meant more possibilities for manufacturing units. Today, CNC machinery is common in multiple industries and is capable of producing a diverse range of products with high levels of accuracy and precision. How CNC Machining Works? Contemporary CNC systems focus on minimizing human intervention as much as possible. This ensures consistent and continuous performance, which facilitates smart manufacturing and delivers excellent results. However, CNC manufacturing requires careful consideration from the initial design to the final manufacturing. The entire process works in three different steps: 1 – Design The first crucial step in CNC machining involves software applications like CAD, CAM, and CAE. Engineers and designers rely on these tools to design parts and products, and then assess their manufacturability. This assessment, known as Design for Manufacturing (DFM), is vital. It ensures that the design is optimized to maximize efficiency and reduce costs, all while working within the constraints of existing technology. In most cases, the CAD tools available in the market come with an internal CAM tool, which facilitates the pre-processing and programming. After finalizing the CAD design, the designer converts it into a CNC-compatible file format, typically STEP or IGES. 2 – Pre-processing and Programming CNC machine programming primarily involves using G-codes and M-codes to communicate with machines. These codes, generated by CAM packages, act as a guide for the cutting tool’s path in CNC operations. Usually, if a design adheres to DFM (Design for Manufacturing) standards, CNC machinists don’t need to intervene in the pre-processing or operational stages. However, if the design doesn’t meet these standards, some level of manual intervention may be required to guarantee optimal performance. Pre-processing is a standard step in CNC machining, and its duration depends on the design’s quality. Programming the G-Codes or M-Codes typically takes just a few minutes. However, the success of CNC programming hinges on the design’s adherence to DFM conventions. Accurate designs produce correct codes and satisfactory results, while design flaws lead to erroneous codes and poor outcomes.   3 – Machining The final stage is the machining process, which uses the provided codes from the previous step to remove excess material from a block. Precision in machine tooling is crucial, yet it’s often challenging to replicate the exact dimensions of a CAD model. This is why machinists typically apply standard ISO 2768 tolerances, which vary based on industry requirements. It’s a widely accepted principle that tighter tolerances lead to increased manufacturing costs.      

As is known to all, optical mechanical parts have extremely strict requirements for light-blocking properties. The better the shading is, the better the precision performance of the product will be. For parts in the optical field. The surface treatment method independently developed by Keso can effectively help customers solve the light-blocking rate of parts. It can achieve a reflectivity of ≤5% (infrared light) in the 700-1000 band. Significantly improve the quality and accuracy of the products. In addition, for local shading and oxidation. Keso also has a mature treatment plan. It can more conveniently assist engineers in prototype design and save research and development time.   2. For the secondary clamping of irregular structural components, due to their structural characteristics, the clamping is difficult and the positioning accuracy is low. This leads to a decrease in processing accuracy and an increase in manufacturing costs. In response to this issue, Keso will develop tooling fixtures separately for the products.
