| 摘要: | 隨著現代科技的發展，材料的使用種類及產品設計需求明顯增多且複
雜。以材料的發展而言，學者專家致力於追求重量更輕、強度更高與成本更
低等特性之材料。而產品的設計，更是越趨複雜以因應越來越多的外在條件
下之作用。然而，複雜的設計於過往經常造成工業製造上的極大挑戰，與極
大的成本支出。為了能有效克服此困境，積層製造技術便應運而生，而此技
術也在近二十年間在各工程領域（如汽車、航太和生醫等）都有蓬勃發展，
甚至被稱為第三次工業革命。
INGROWS PU 簡稱為IPU 為近年來由可成生技公司新研發之線材，其
系與積層製造常用線材TPU (熱塑性聚氨酯)有相似特性，亦同屬熱成型塑
膠類材料；然而，因此線材於一般文獻中不易找到精確的材料參數，且無法
確認在不同列印方式，甚至是環境因素下是否會對材料特性及參數造成影
響。故此本研究主要欲結合積層製造與IPU 線材，探討IPU 線材成型之力
學特性。主要探討方式將由實際試驗與數值模擬同時著手，探討材料成型後
之受力行為與其相對應之彈性與塑性特性。實際試驗系利用計有泛能試驗
機進行抗拉與抗壓試驗；數值分析則使用物質點法。此外，本論文亦將深入
分析各材料參數，如楊氏模數與塑性階段時之切線模數。
綜上所述，此一系列之IPU 線材成型後之力學試驗與數值分析成果均
可作為後續產品設計與開發時之重要參考依據。;With the advancement of modern technology, the variety of materials used
and the demands of product design have significantly increased and become more
complex. In terms of material development, scholars and experts are dedicated to
pursuing materials that are lighter, stronger, and more cost-effective. Product
design has also become increasingly intricate to meet the growing number of
external conditions and requirements. However, complex designs have
historically posed significant challenges and incurred substantial costs in
industrial manufacturing. To effectively overcome these difficulties, additive
manufacturing technology emerged. Over the past two decades, this technology
has flourished in various engineering fields, such as automotive, aerospace, and
biomedical industries, and has even been referred to as the Third Industrial
Revolution.
INGROWS PU, abbreviated as IPU, is a newly developed filament by Acme
Biotechnology. It shares similar properties with TPU (thermoplastic
polyurethane), a material commonly used in additive manufacturing, and belongs
to the category of thermoplastic materials. However, precise material parameters
for this filament are difficult to find in common literature, and it is unclear whether
different printing methods or even environmental factors might affect its
IV
properties and parameters. Therefore, this study aims to combine additive
manufacturing with IPU filament to investigate the mechanical properties of IPU
filament formation. The main approach will involve both experimental testing and
numerical simulation to examine the material′s behavior under stress and its
corresponding elastic and plastic characteristics. The experimental tests will be
conducted using a universal testing machine for tensile and compressive tests,
while the numerical analysis will employ the Material Point Method. Additionally,
this thesis will delve into various material parameters, such as the Young′s
modulus and the tangent modulus during the plastic stage.
In summary, the results of the mechanical tests and numerical analyses of the
IPU filament series can serve as important reference data for future product design
and development. |
