Biomedical 3D Printing

Good morning, I bought an octopus v1.1 mainboard, I configure the marlin normally but the motor connected to input E0 does not work, the status of the motor and the cable are fine, I checked it by connecting to other inputs on the card but the extruder does not work,My petg 3d printer filament cannot come out of the nozzle either I have looked for different sources and no solution works, when connecting the motor it does not rotate, but it does not vibrate either, the current connection of the extruder is in motor 4. Could you help me?

Choosing a 3D printer within your budget of 1000€ that can handle both small and large prints can be a bit challenging, If you frequently need to print items larger than 50cm x 50cm, a larger printer like the Creality CR-10 V3 or Artillery Sidewinder X1 would be more suitable.If you're willing to assemble larger items and value detail for smaller prints, a smaller but high-quality printer like the Prusa i3 MK3S+ could be a better choice.Remember to also factor in the cost of filament, especially if you plan on printing a lot, as this can add up over time. In addition, I would like to recommend PLA filament to you,PLA is an easy-to-print biodegradable material that is affordable, although it has lower strength and heat resistance. However, it remains a cost-effective choice for some medical modeling and non-implant medical product printing.

The other day I took my daughter to have her teeth orthodontic, and I found that with the continuous progress of technology, 3D printing technology is more and more widely used in the medical field, especially in the dental field. So I conducted an in-depth study in this area. FDM (Fused Deposition Molding) 3D printing technology is changing the traditional dental treatment and manufacturing process with its efficient, precise and personalized characteristics. One of the applications of FDM 3D printing technology in dentistry is to make crowns and Bridges. The 3D printing filament used in different parts are also different, The traditional process of making the crown and bridge is complicated, which requires multiple molds and adjustments, which takes a long time. With FDM 3D printing, doctors can first digitally scan a patient's mouth and then use that data to quickly generate an accurate digital model. The 3D printer then stacks the material layer by layer to create a crown and bridge that perfectly matches the patient's mouth. This method not only improves the production accuracy, but also greatly reduces the treatment time. Another application is to create personalized dentures. The production of traditional dentures usually requires hand carving and multiple tries, which is a complicated and inefficient process. Using FDM 3D printing technology, doctors can design and print dentures that fully meet the requirements of patients according to their oral structure and needs. This personalized manufacturing not only improves the comfort of dentures, but also reduces the number of visits and enhances the overall patient experience. Applications of FDM 3D printer technology in dentistry also include the production of surgical guides and orthodontics. The surgical guide can help doctors accurately control the position and orientation of the implant during the implantation surgery, reduce the surgical risk and shorten the treatment time. Orthodontics can be customized according to each patient's tooth condition to achieve accurate correction. With the continuous development of materials science and 3D printing technology, the application of FDM 3D printing in dentistry will be more extensive. From personalized dental restorations to complex surgical guides, 3D printing technology is driving dental medicine to a more efficient, accurate and personalized direction. In the future, we can expect more innovative applications to bring better oral health and treatment experiences to patients.  

Today, with the increasing maturity of 3D printing technology, PLA filament is one of the most common printing materials, and its use and management are becoming more and more important. Among them, the rewinding process of bulk PLA filament is a link that cannot be ignored. First, the return shaft of the bulk PLA filament helps to save costs. For many 3D printing enthusiasts and professional users, the use of filament is large, and the remaining filament can be reused through the back shaft to avoid waste, thereby reducing printing costs. Secondly, the return axis of the filament can keep it clean and orderly. In the 3D printing process, the filament often becomes disorganized, which not only affects the beauty, but also may lead to printing failure. After the return axis, the filament is neatly arranged, easy to manage and use, and improves the efficiency and success rate of printing. In addition, the return axis of the filament helps to reduce environmental pollution. With the popularity of 3D printing technology, the disposal of waste filament has become an environmental problem that cannot be ignored. Through the return shaft, the service life of the filament can be extended, the generation of waste can be reduced, and the concept of environmental protection can be met. Finally, the return axis of the filament is also a protection for the properties of the material. In the process of returning the shaft, the damage or pollution of the filament can be found and treated in time to ensure that it can maintain a good printing effect in the next use. So the return shaft of bulk PLA filament is of great significance in saving cost, keeping clean, environmental protection and material protection, and is worthy of our attention and promotion.

bulk filament is a key production material, and its regular inventory is of great significance. First of all, the inventory quantity and status of the filament can be accurately grasped through regular inventory, and the problem of excessive storage or shortage can be found and dealt with in time. This helps companies optimize inventory management to avoid affecting production schedules due to insufficient filaments or taking up too much capital due to excessive inventory. Secondly, regular inventory can ensure the quality of the filament. Through regular inspection, it can be found in time whether the filament is damaged, expired and other problems, so as to take corresponding measures, such as replacement or repair, to ensure that the production of the filament are in line with the standard, improve product quality. In addition, regular inventory also helps enterprises to control costs. Through accurate inventory management, enterprises can better predict the demand for filament, rationally arrange procurement plans, avoid paying excessive prices due to emergency procurement, and further reduce production costs. To sum up, the regular inventory of bulk filament plays a vital role in the production management, product quality and cost control of enterprises, and is an indispensable management link of enterprises.
