چکیده
با گسترش فناوری ساخت افزایشی، تنوع دستگاههایی که بتوان در محیط های کوچک اداری و تجاری و یا آموزشی مورد استفاده قرار داد بیشتر می‌شود. در این پژوهش هدف ساخت یک چاپگر سه بعدی رومیزی با فناوری تف جوشی انتخابی لیزر است که برای امور پژوهشی قابل استفاده بوده، قطعات آن ساخت داخل بوده و یا از بازار داخلی قابل تهیه باشد و همچنین با نرم افزارهای متن باز رایج چاپگرهای سه بعدی سازگار باشد. چاپگر سه بعدی ساخته شده توانایی کار با انواع پودرهای پلیمری رایج را دارد. علاوه براین به راحتی می‌توان میان افزار دستگاه را با توجه به نیاز پژوهشگر بروزرسانی کرد. این دستگاه با پودر گلوکز، پودر موم پارافین و ترکیبات مواد گرمانرم - سرامیک تست شده و در حال حاضر برای پژوهش‌های ساخت قطعات سرامیکی با تف جوشی انتخابی غیر مستقیم لیزر مورد استفاده قرار می‌گیرد.

چکیده English

With the development of additive manufacturing technology, the quantity of devices that can be used in small office with the commercial or educational purposes increases. In this research, the goal is to build a desktop 3D printer with selective laser sintering technology, which can be used for research purposes. The main concentration is focused on fabrication with parts that can be manufactured in the country or can be procured from the domestic market. It is also tried to make the 3D printer compatible with the common open-source additive manufacturing softwares. The fabricated 3D printer has the ability to work with all kinds of common polymer powders. In addition, it is easy to update the device's firmware according to the researcher's needs. The capabilities of the device was tested with Glucose powder, paraffin wax powder, and thermoplastic-ceramic material combinations. It is currently used for research on fabricating ceramic parts with indirect laser sintering.
