新款尼龍塑料進入3D Printer戰局！（義大利製）
New Nylon filament for 3D printers, made in Italy
義大利公司 3ntr 發表一款新的尼龍塑料，是為 3D Printer 量身訂製的。這款 3mm polyamide 6 filament 成分是 99.9% 的 PA6 Polymer（聚醯胺 6，一種特殊的工程塑料），不參雜任何的塑化劑與玻璃纖維，剩餘的 0.1% 是肥皂，用來簡化加工。這款塑料不同於 Taulman's Nylon 具有彈性，其特性是讓列印出的材料對靜載重與活載重有更佳的對應性。
Italian company 3ntr has launched a new nylon filament developed specifically for 3d printers. This 3mm polyamide 6 filament is made up of 99.9% PA6 Polymer, no plasticizers, no fiberglass, and 0.1% soap to ease processing. It is not as flexible as Taulman's Nylon, but it is aimed to print structural parts that must be able to resist static and dynamic loads.
根據 3ntr 公司的說法，polyamide 6 的列印設定趨近於 ABS，只有列印的溫度不同（240-280°C，高於ABS的220°C），列印厚度只要設定 0.25mm 就可以得到最佳的列印結果。
此外，polyamide 6 在黏稠度上具有不同的特性（相較於 PLA 與 ABS 等常見的家用 3D Printers 塑料），該公司建議使用者使用電木（[法] bachelite／[英] bakelite ）或是尼龍作為底板，以得到最佳的列印效果。使用這種塑料時，並不用開啟加熱底板，在列印第一層的時候，厚度設定為標準層的 80% 就夠了。最好的列印速度是 70 mm/sec，如果要獲得最佳的附著性，速度要降為 40 mm/sec。
According to 3ntr, settings for printing polyamide 6 are similar to ABS, only the printing temps should be 240-280°C, and the best printing results can be obtained with layer thinner than 0.25mm.
In addition, Polyamide 6 has different adhesion properties from other common use plastic for 3D printers (PLA or ABS), 3ntr suggests users to use bachelite or nylon bed for the best result. And it is not necessary to heat the plate, in this case setting the first layer thickness to be 80% of standard layer is enough. The maximum advisable speed is 70 mm/sec, though the best adhesion is obtained at 40 mm/sec.
3ntr 成立于五十年代末，當時主要在生產緊身衣部件。現任的行政總裁 Davide Ardizzoia 先生是一名紡織工程師，同時也是 3D 繪圖軟體 Rhinoceros 的資深用戶（超過12年），具有電腦圖形背景，在幾家機器人和電腦控制的公司都有涉略。
＂真逗趣，我們沒有使用上最新的技術 （直線電機、 雷射器、 機器人、 超聲波焊接機、 微粉化的聚合物、 熱熔系統）"，Ardizzoia 說。"七年前我們一腳踩進快速成型的世界。對於這項技術的可能性實在讓我們感到驚訝，但也付出了巨額的費用＂。根據 Ardizzoia 口述，一些獨立的測試者報告指出，polyamide 6 有近似於 Taulman 618 的列印特性，差別是 polyamide 6 較不容易捲曲。
3mm polyamide 6 filament 目前只有白色可以選擇。黑色尼龍仍處於調教的過程，希望能獲得一致性的結果。價格是每線軸（450克）25€（33美金，約一千台幣）。以下是一些列印的聚醯胺 6 的測試：
3ntr was established in late fifties to make corsetry parts. Current CEO Davide Ardizzoia was a textile engineer, an early user of Rhinoceros (12+ yrs), with a computer graphics background, peppered with several stages at robotics and machine control companies.
"Funny enough we end up using latest technologies (linear motors, lasers, robots, ultrasonic welders, micronized polymers, hot melt systems)", says Ardizzoia. "Seven years ago we stepped into rapid prototyping. We were amazed both from the possibilities of the technology but also from the huge costs involved." According to Ardizzoia, some independent beta testers reported that polyamide 6 has more or less same printing behavior as Taulman 618, only polyamide 6 is a little less "warpy".
The 3mm polyamide 6 filament is currently available in white color. The black nylon is still in its fine-tuning process to get consistent results. The price is 25€ ($33) per spool (450 gr).
