Customers frequently inquire whether it is more cost-effective to purchase a 3D printer to print themselves or to purchase a 3D printer to print themselves because there is a demand for 3D printing every month. According to the price of about $100 3D printers on Taobao Search, the cost is not prohibitively expensive and appears to be extremely cost-effective. Should we, on the other hand, invest in a 3D printer? What, aside from cost, are the other considerations that are often overlooked? Let's get started on this problem today and see where it takes us.3D printers are classified into several categories.The majority of the time, What is 3D Printing can be divided into two categories: desktop level 3D printers and industrial level 3D printers. Desktop level 3D printers are frequently used to print smaller objects, primarily for educational, maker, and simple model-making purposes, rather than large objects. Industrial 3D printers are widely used in a variety of industries, including aerospace, automobile manufacturing, medical treatment, mold manufacturing, jewelry manufacturing, and others. The printed products have the potential to be used on an industrial scale.What are the main differences between desktop and industrial printers, aside from the application areas in which they are used?Identifying the distinction between desktop and industrial 3D printers1. The basic operating principleGenerally, the FDM principle is used at the desktop level. This principle is based on the melt deposition modeling technology, filamentous consumables, and strip plastic that has been heated and softened by the printing head. Extruded materials and melt thermoplastic materials are deposited layer by layer through the nozzle in accordance with a computer-generated 3D model of the material. SLA, 3DP, and SLS are all examples of the process level principle. SLA is a product that is widely available on the market. Laser scanning is used in conjunction with a computer-generated three-dimensional pattern to selectively allow the liquid photosensitive resin to undergo polymerization reaction, resulting in a hard modeling surface as a result.2. ReliabilityThe geometric tolerance and part precision of 3D printers are dependent on the calibration and model complexity of the models being printed. When it comes to controlling the processing parameters during the printing process, industrial 3D printers are more stringent. So the precision of industrial 3D printers is higher than that of desktop 3D printers, and the accuracy distortion can be avoided more effectively than with desktop 3D printed parts. The structure has a negative impact on the printing accuracy, as well as the maximum printing size and the printing reliability of the print. The low success rate of printing, particularly for novices, indicates that there is a high likelihood of waste products being produced.3. The printing speedTypically, desktop printers use 16-bit and 32-bit chips as the primary control chip, and the data processing speed is difficult to compare to that of a 64-bit CPU. In SLA technology, the former can scan at speeds of up to 1 m/s, while the latter can scan at speeds of 7-15 m/s. If the Western ink jet printer and similar project series are used, the desktop level 3D printer will be unable to operate at all due to the large number of ink droplets being carved at the same time, which can reach hundreds.4. The cost of the printerGenerally speaking, desktop level 3D printers are of simple construction, and the price ranges from several hundred thousand to several hundred thousand yuan; the industrial 3D printer, on the other hand, is of relatively complex construction. The machine model is often large, the fuselage cost is high, and the research and development cost is high, and the price ranges from tens of thousands to hundreds of thousands, and in some cases, it can reach millions of yuan. Process grade 3D printers have a high production capacity, print quickly, and have high precision, but they are more expensive. Desktop 3D printers are relatively inexpensive, but their precision is limited; process grade 3D printers have a high production capacity, but their precision is limited. The cost of purchasing a 3D printer with satisfactory performance is still prohibitively expensive. Furthermore, 3D printers have a high threshold for failure and a high maintenance cost for non-professionals.The 3D printer's threshold and ongoing maintenance costs1. Consumables are prohibitively expensive to purchase.The cost of standard consumables in volume is not prohibitively expensive, and the cost of a litre of photosensitive resin ranges between 500 and 800 yuan per liter. Special consumables, on the other hand, must be imported, which is both expensive and does not provide a price advantage.2. Exorbitant maintenance costsMaintenance over a long period of time: it is necessary to perform maintenance once a month and to be thorough in cleaning dust, wiping bar, bearing oil, and residual slag from the feed gear.When printing, maintenance should be performed as follows: prior to printing, the last scrap should be extruded first, and the glass platform should be cleaned with water before use in order to ensure that there is no residue printed before the hot bed and that the consumables allowance can support printing; after printing, maintenance and cleaning should be performed as follows:During printing, do not touch the print head or platform, do not interfere with the movement of the print head, and do not pull the card out of the Online 3D Printing , as this will cause the 3D printer to become worn.Following printing, the nozzle should be checked for wear in a timely manner, and the new nozzle should be installed in a timely manner.3. The machine must be debugged by a professional department prior to being put into service.The success rate of printing will be affected by the amount of time spent debugging. Failure to process a specific detail will result in the entire printing product being wasteful. A calibration algorithm is run on the 3D printer before each print, and it has a heating chamber to reduce the impact of rapid cooling of molten plastics (such as warping), and it can print at higher temperatures than most 3D printers. Before formal printing, the model must be layered and converted into printing instructions, which requires programming technology and frequently requires the assistance of a professional printer.4. Difficulties following treatmentAfter the printing process is completed, additional processing is required to create the final product. Cleaning parts, removing supports, and grinding are all common post-treatment procedures for automobiles. If you print it yourself, then you are the only one who can complete this work.Parts that need to be cleanedWhen the print is removed from the printer, it will be covered by cured resin, which will need to be removed before any further treatment can be performed. In most cases, an ultrasonic bath is used, and enough isopropanol (IPA) is injected into the bathtub to completely cover the print, after which it is cleaned after several minutes of standing.Support should be removed.After the print has been cured, remove the tree support structure that was attached to the print and discard it. This procedure should be carried out manually, with care taken not to break the support in order to avoid damaging the print.the language of the polonaiseIt is possible that the removal of the support parts will leave a mark. It may be necessary to grind the surfaces of printed parts if the surface details are particularly fine or if a specific color is required in some cases.5. Toxic gas may be released during the printing process.Researchers at the University of Texas published a study in which they concluded that using ABS resin as a printing material was harmful to one's health because it contained styrene, which is a known carcinogen.For example, if you have low precision requirements, or if you are an avid 3D printing enthusiast, you can purchase a desktop 3D printer if you have the time and energy to research this field; if you need to print frequently and have high precision requirements for print parts, you can purchase an industrial 3D printer, but you will need to set up a dedicated team to support it. Thus, there are specific requirements for details, the initial budget is not excessive, and the proofing demand is not very high for small and medium-sized businesses. It is recommended that the printing requirements be distributed.
