I want to have a 3D printer for printing models, small parts, or mobile phone cases. I don't know what is better? What materials are used? I can only use UG. Is this printer supported? Will there be a desktop CNC and 3D scanner in the future? I know I have a lot of questions. Which brand is more suitable for home use? I hope you can recommend it.
supplementary question:
Thank you!

1. 3D printer speed:
According to the different manufacturers of rapid prototyping equipment, or the different 3D printing technology adopted, the measurement standard of 3D printing speed is different. Some are used to indicate the time required to print a certain height in the Z-axis direction (for a single 3D printing task), usually expressed in inches/hour, mm/hour. Those 3D printers with a stable vertical construction speed generally like to use this technical parameter, which is basically not affected by the complexity of the structure of the printed object and the number of parts printed in a single time. This kind of 3D printer is an ideal choice for 3D printing of prototype models, because they can quickly produce a considerable number of various models in a limited time, which is convenient for design communication, discussion and comparison.
Another technical parameter to measure printing speed refers to the time required to print a specific object or a specific volume. Some 3D printers can quickly print a single object with a simple structure, and often use this indicator. However, when this type of 3D printer encounters an increase in the number of prints or a more complex structure, the printing speed will drop significantly, so it is not suitable for rapid prototyping of prototype models with high printing speed requirements. Common models include fdm plastic printers and sla/dlp resin printers; here are divided into desktop and industrial, if you are personally buying a desktop machine, it is recommended.
2. the price of 3D printers:
If you are planning to buy a machine for service, please read this paragraph
The cost of printing is usually expressed in terms of the cost per unit volume. Even if the same 3D printer is used, due to the influence of the structure of the molded part, the cost of a single molded part is very different. Therefore, the quotation of 3D printing services is often presented at the typical object printing price or the average price, which is not difficult to understand NS. If you need to compare the quotations, you can provide a set of STL data of your own classic samples for the supplier to make a quotation, and clearly know what is included and not included in the different quotations, so as to choose the most cost-effective supplier.
The quotations provided by some suppliers only include the cost of the model materials required for the molded parts, and do not include the support materials or other losses incurred during the 3D printing process. This quotation is not a true and final quotation. The material utilization rate of different 3D printing processes varies greatly. Therefore, the actual material usage cost is another important reference for measuring the quotation.
The price of the machine is discussed here. In fact, if you buy from the Internet, it is recommended to buy directly from the manufacturer’s official flagship store. Do not buy from a third-party platform, because the manufacturer can still cut the price appropriately, or send more consumables. Normal; and the after-sales service will be more secure; to get back to the point, the price of the machine in China is currently ranging from 500 to 30,000, I am talking about fdm desktop 3d printers; you can choose according to your actual ability;
PS: If it is used for work, the recommended price should not be less than 5000 yuan for the machine.
3. the accuracy of the 3D printer:
If it is fdm, the machine error is generally between 0.2-0.4, but it is not ruled out that there is a machine with an error of 1mm; how to distinguish this, as a novice who does not know anything; the method is very simple if you want to know how much the real error is , You can directly find a model for the seller to try to print, and send the printed finished model to you. You can directly measure the caliper to know the true error; this printing fee will also be refunded to you when you buy the machine, but remember first After comparing a number of comparisons and finding a favorite to print, the cost is generally not more than 200 yuan; here to add, the printing accuracy of the printers with the same price is really similar and not too big; if you buy a very cheap machine, Please skip the trial printing step directly, or it will be a waste of money.
