Curved Layer Fused Deposition Modeling

Current Fused Deposition Modeling (FDM) technologies deposit material as flat layers. The result is a “stair-case” effect on non-vertical or horizontal surfaces, and compromised part strength because of weakness between the laminations. This paper describes a FDM method through which layers of build material are deposited as curved layers following the shape of the part, thus removing the stair...

تدوین راه کار های کاربردی برای ساخت قطعات به روش fused deposition modeling با کاهش هزینه ساخت

فرآیندهای ساخت به روش افزودنی از دسته فرآیندهای تولیدی نوین صنعتی است که بر خلاف روش های مرسوم تولیدی، مانند جداسازی مواد(تراشکاری, فرز کاری و ...) و فرم دهی(کشش عمیق، اکستروژن و ...)، بر اساس افزودن لایه لایه مواد بر روی یکدیگر، تولید قطعات را انجام می‏دهند. فرآیندهای ساخت به روش افزودنی بر اساس نوع ماده مصرفی به سه دسته مایع پایه، پودر پایه و جامد پایه تقسیم بندی می شوند. فناوری مدل سازی با ر...

Anisotropic Mechanical Properties of ABS Parts Fabricated by Fused Deposition Modelling

Dual-color mixing for fused deposition modeling printers

In this work we detail a method that leverages the two color heads of recent low-end fused deposition modeling (FDM) 3D printers to produce continuous tone imagery. The challenge behind producing such two-tone imagery is how to finely interleave the two colors while minimizing the switching between print heads, making each color printed span as long and continuous as possible to avoid artifacts...

Extruder path generation for Curved Layer Fused Deposition Modeling

Extruder path generation for a new rapid prototyping technique named “Curved Layer Fused Deposition Modeling” (CLFDM) has been presented. The prototyping technique employs deposition of material in curved layers in contrast to flat layers as in Fused Deposition Modeling (FDM). The proposed method would be particularly advantageous over FDM in the manufacturing of thin, curved parts (shells) by ...
