With the changes in the market, development, many companies will consider buying wax mold 3D printer for printing wax molds (for metal casting and other industries), but for many companies who have not been exposed to 3D hit the equipment may not know much about this aspect, this is the purpose of this article, so that the intention to buy equipment for the enterprise to have an overall understanding of avoiding unnecessary trouble.

I. Define your own needs

Before embarking on a purchase, be sure to clearly sort out your usage needs. For example, determine which field you will mainly use it in, whether it is jewelry making, industrial parts manufacturing or medical model production, etc. Different fields have different requirements on the accuracy, size and material properties of wax models. At the same time, to estimate the approximate amount of printing, is occasionally a small amount of printing for prototyping, or the need for batch, large-scale production, which will affect the printer printing speed, build size and other aspects of the choice, in order to circle the printer type and the general parameters of the range of needs, to avoid blind selection.

Second, understand the printer performance parameters

1. Printing Accuracy: Focus on the minimum layer thickness and the overall dimensional accuracy of the equipment. For example, the production of fine jewelry wax models may require printers with small layer thicknesses (tens of microns) to ensure that textures and other details are clearly presented; while for some industrial functional wax models, the dimensional accuracy needs to be strictly in line with the design requirements to prevent subsequent casting and other processes from having fitment problems.
2. Printing speed: Examine the volume of molding per unit of time and the performance of print speeds for models of varying complexity. If there are mass production tasks, faster printing speed can improve efficiency and shorten the production cycle, but also note that some printers may plummet in speed when handling complex models, which needs to be weighed in the balance.
3. Build Size: Define the maximum size of wax model that can be printed by the printer, and choose it in relation to the size of wax models that are often made in actual business. At the same time, understand the utilization efficiency of the effective printing area to avoid the situation that the nominal size is large but the actual available space is limited, which affects the printing of special shape wax models.
4. Wax Powder Material Compatibility: Check the supported wax powders to make sure that they are suitable for the material you plan to use, especially those with special performance requirements (e.g. high temperature resistance, high strength, etc.). In addition, the convenience of the material changeover is also important for the efficiency of the subsequent use. If the material has to be changed frequently, a cumbersome changeover process will waste a lot of time.

III. How to avoid common buying traps

1. Be wary of over-promotion: Some manufacturers may exaggerate the performance parameters of their printers, such as claiming ultra-high precision that is difficult to achieve in actual use, or boasting extremely fast print speeds without stating that it is under a specific simple model. To carefully check the actual technical specifications in the product manual, and as far as possible to request a live demonstration or view the actual print samples to verify the authenticity of the promotional content.
2. Avoid the temptation of low pricesWax 3D printers that are priced too low often have shortcomings in terms of quality, performance or after-sales service. Do not simply be attracted by the low price, but comprehensively compare the configuration, functions, reputation, etc. of products at different price points to analyze their cost-effectiveness and prevent buying equipment that seems cheap but has frequent problems in subsequent use and high maintenance costs.
3. Look for hidden clauses: When signing the purchase contract and other documents, read the terms and conditions carefully and pay attention to whether there are any hidden fee clauses (e.g. charges for software upgrades at a later stage, high-priced charges for the replacement of certain key accessories, etc.) or ambiguous expressions of key after-sale contents such as the scope of the warranty of the equipment and the time, so as to avoid any unnecessary disputes and additional expenses in the subsequent period.

IV. Ensuring the quality of after-sales service

1. Technical support responsivenessUnderstand the technical support channels provided by the manufacturer, such as whether there is a 24-hour customer service hotline, online technical support platform, etc., and ask about its average response time. When problems are encountered in the process of use, it is crucial to get professional technical guidance to solve the problems and resume production in a timely manner.
2. Repair service and spare parts supply: Examine the manufacturer's maintenance service network coverage, can arrange timely maintenance personnel to repair (especially for large, heavy industrial-grade printers this is very critical). At the same time, to confirm whether the supply of original spare parts is sufficient, timely, to avoid equipment failure due to waiting for parts and long downtime, in addition, to understand in advance the approximate costing of maintenance costs, to ensure that the cost of maintenance in the later acceptable range.
3. Training services: For first-time users, good training services can help operators quickly familiarize themselves with the operation and maintenance of the equipment. Ask the manufacturer whether to provide free operation training, training content is comprehensive (covering the use of software, routine maintenance, simple troubleshooting, etc.), to ensure that the equipment can be put into use smoothly after arrival.

V. Importance of user evaluation

1. Multi-channel collectionThe user reviews of related products can be searched through the Internet, such as professional 3D printing forums, e-commerce platform buyer reviews, industry exchange groups, etc. Different channels can obtain more comprehensive and objective feedback. Different channels can obtain more comprehensive and objective feedback, from the printing effect, stability to after-sales service and other aspects, to understand the real experience of other actual users in the process of use. Of course, every product is not perfect, from the many brands to choose a better is our purpose.
2. Focus on content: Focus on the frequency of equipment failure, printing accuracy is stable, after-sales service to solve the problem of the actual effect and other key elements of the evaluation. For example, if more than one user feedback on a printer often appear a variety of faults and can not be used, it is necessary to carefully consider the purchase of this product; if the general praise of the manufacturer's after-sales maintenance in a timely manner, a good attitude, then the after-sales aspects of the relative more secure.
3. Compare different brands and models: Compare and analyze the collected user reviews of different brands and models of 3D printers to find out the products with better reputation and high comprehensive satisfaction in all aspects, which will help narrow down the choices and make more appropriate purchase decisions. If necessary, you can personally visit the supplier in the factory, after all, large wax model 3D printer are not cheap, personal communication can learn a lot of useful information. Face-to-face communication is important, and for really strong brands they are happy for you to visit them in person.

In conclusion, when buying a wax 3D printer for the first time, it is important to do your homework, consider all factors, and make a careful choice in order to get a device that meets your needs and saves you money in subsequent use.
