Za razliku od izotropnih materijala, +kod kojih su mehanička svojstva jednaka u svim smjerovima, FDM dijelovi pokazuju značajnu razliku u čvrstoći između slojeva (po osi izgradnje slojeva, tj. Z-osi).\\ +Glavni uzroci slabosti među slojevima su:\\ + +\begin{enumerate} + \item \textbf{Ograničena difuzija molekula}\\ + Tijekom taloženja slojeva, novi sloj rastopljenog filamenta dolazi u kontakt s već ohlađenim slojem ispod. Prava kemijska veza između slojeva može nastati + samo ako dođe do \textit{difuzije polimernih lanaca} preko granice slojeva \cite{sun2008effect, rods2001diffusion}. Ako je razlika u temperaturi prevelika, + ili je vrijeme kontakta prekratko (zbog velike brzine kretanja mlaznice), dolazi do mehaničkog prijanjanja te nastaje "hladan spoj" dvaju slojeva u + kojemu nema stvarne kemijske veze između slojeva. + \item \textbf{Temperaturni gradijenti i brzina hlađenja} \\ + Brzo hlađenje prethodnog sloja sprječava djelomično taljenje pri dodavanju novog sloja, što rezultira slabijom vezom \cite{coogan2017thermal}. + Uspješno međuslojno prianjanje ovisi o toplinskoj vodljivosti materijala, viskoznosti rastaljenog polimera i vremenu difuzije. + \item \textbf{Geometrijski i reološki faktori} \\ + Parametri poput visine sloja, širine ekstruzije i brzine taloženja utječu na oblik i površinu kontakta između slojeva. Veće visine sloja i manja širina + traga smanjuju površinu kontakta, čime se povećava vjerojatnost loma na slojevima \cite{aoyagi2002viscosity, basgul2017layeradhesion}. + \item \textbf{Zračni među-prostor (voids)} \\ + Nedovoljno preklapanje tragova i slojeva može rezultirati stvaranjem \textit{mikropraznina} koje djeluju kao koncentratori naprezanja + \cite{kuznetsov2018strengthPLA, bellini2003mechanical}. One su često inicijalne točke loma pri mehaničkom opterećenju. + \item \textbf{Efekt taloženja pod kutom} \\ + Kod nagnutih ili kompleksnih geometrija, slojevi se ne talože ravno jedan na drugi. To dodatno smanjuje efektivnu nosivu površinu, što posebno dolazi + do izražaja kod savijanja ili smičnog opterećenja \cite{sun2008effect}. + +\end{enumerate} + +\subsubsection{Ponašanje u smiku i vlačna čvrstoća}\label{ponasanje_u_smiku_i_vlacna_cvrstoca} + +Zbog prirode taloženja slojeva u FDM tehnologiji, 3D printani dijelovi pokazuju snažno anizotropno ponašanje u pogledu mehaničkih svojstava. Najveća razlika očituje se pri usporedbi čvrstoće u smjeru paralelnom sa slojevima (X-Y ravnina) i smjeru okomitom na slojeve (Z-os), posebno pri različitim vrstama opterećenja. + +\begin{itemize} + \item \textbf{Vlačna čvrstoća} u X-Y ravnini najčešće je značajno veća od one u Z-smjeru, jer se u ravnini sloja ostvaruju kontinuirani tragovi filamenta koji su dobro povezani. Pri vlačnom opterećenju u Z-smjeru, čvrstoća ovisi isključivo o kvaliteti međuslojnog prianjanja \cite{aulia2021tensileanisotropy}. + + \item \textbf{Smična čvrstoća} još je osjetljivija na anizotropiju. Kod opterećenja smikom, osobito u Z-X ili Z-Y ravnini, deformacija se odvija duž granica slojeva gdje su veze najslabije. Studije pokazuju da smična čvrstoća može biti i do 70\% niža od vlačne u X-Y ravnini \cite{panoto2019shear}. + + \item \textbf{Karakter puknuća} također varira — kod vlačne sile u Z-smjeru lom se često događa iznenada i duž granice slojeva, dok je u X-Y ravnini lom postupniji, jer materijal ima veći kapacitet deformacije prije loma \cite{zandi2020mechanical}. + + \item \textbf{Utjecaj parametara ispisa} (poput visine sloja, postotka ispune i orijentacije modela) izraženiji je kod smičnog opterećenja jer ovi parametri direktno utječu na povezanost između slojeva i tragova unutar slojeva. +\end{itemize} + +Zbog navedenog, odabir parametara ispisa mora se prilagoditi vrsti opterećenja kojoj će dio biti izložen. Ako se očekuju sile savijanja ili smicanja u Z-smjeru, preporučljivo je koristiti manje visine slojeva, veću širinu ekstruzije i više slojeva stijenke kako bi se poboljšala kohezija među slojevima. + + + + +\subsection{Taguchijeva metoda} \label{subsec:taguchi_metoda} + +Taguchijeva metoda je eksperimentalna strategija za analizu utjecaja više ulaznih parametara na neki izlazni odziv sustava, s ciljem optimizacije performansi uz minimalan broj eksperimenata.

Najčešće korištene su matrice tipa L9, L18, L27 itd., ovisno o broju faktora i razina. + + \item \textbf{Signal-šum omjer (S/N omjer):} Kvantitativna mjera kojom se procjenjuje kvaliteta odziva. Povezuje korisni signal (željeni odziv) s neželjenim šumom (varijacijom). Za slučaj kada se želi maksimizirati odziv (npr. čvrstoća), koristi se S/N omjer za kriterij "što veće, to bolje": + + \begin{equation} + \text{S/N} = -10 \cdot \log_{10}\left( \frac{1}{n} \sum_{i=1}^{n} \frac{1}{y_i^2} \right) + \end{equation} + + gdje je $y_i$ izmjerena vrijednost odziva u $i$-tom ponavljanju, a $n$ broj ponavljanja eksperimenta za danu kombinaciju parametara.\\ +\end{itemize} + +\begin{flushleft} +\textbf{Zašto se koristi u optimizaciji procesa:} + +U klasičnom pristupu, ako postoji $k$ faktora, svaki s $l$ razina, potrebno je provesti $l^k$ eksperimenata za potpunu faktorsku analizu.
