 The below code is written in MATLAB it gives the coordinates when any object in an STL file is sliced at a desired height. Input: STL file. Output: Slice profile at a given height.   clc; clear all; FV = stlread('A3.stl'); %d the stl file [F,V,N]=stlread('A3.stl'); %d Reading Stl file sz= F.Points; %d Reading the cordinates ma= max(sz(:,3)); mi= min(sz(:,3)); disp('Z must be between'); disp(ma); disp('and') ;disp(mi); z= input('Enter Z height:'); km= F.ConnectivityList; l=size(km); i=l(1); ka=1; for j=1:i p=km(j,1); q=km(j,2); r=km(j,3); k1=sz(p,3); k2=sz(q,3); k3=sz(r,3); g1= max([k1,k2,k3]); g2= min([k1,k2,k3]); if ((g2<=z) & (z<=g1)) if ((sz(p,3)<=z) & (z<=sz(q,3)) | ((sz(q,3)<=z) & (z<=sz(p,3)))) m= ((z-sz(p,3))/((sz(q,3)-sz(p,3)))); ...

                                            Role of Microstructure on Hardness                                      Key words- Selective laser melting (SLM), 316L Stainless steel (316L SS), Cold spraying (CS), and Cold rolled (CR).   I.     I NTRODUCTION T he Hardness is the measure of a material’s resistance to deformation by surface indentation or by abrasion, some even say it is the quantity that describes strength & heat treatment, some say it is the resistance to permeant deformation but here I will be taking hardness as the resistance to surface indentation.   So here I will be discussing various ways to increase hardness by changing the microstructure of the material, which can be sai...
