It delves into the distinctions between subtractive and additive manufacturing, highlighting the advantages and disadvantages of each. The text elaborates on two primary additive manufacturing methods: Fused Deposition Modeling (FDM), which uses filament, and Stereolithography (SLA), which utilizes resin. FDM is described as suitable for large models with fine detail, though slower and non-toxic, while SLA excels in producing extremely fine details for smaller models, albeit involving hazardous chemicals and moderate speed. The document further details the resin printing process, involving exposing resin to UV light to achieve hardening, and the steps for preparing and executing a print from a 3D model file. It also mentions the potential for 3D printing in manufacturing, contrasting it with injection molding in terms of startup costs, unit costs, and optimal production volumes. The document suggests resources for finding 3D models, particularly for ham radio enthusiasts, and lists various components that can be printed.","# 3D Printing:What's It All About?\n\nPaul Holzworth,KD4BFNHPH@NC.RR.COM  \n# Make Things\n\n▶ Ham Specific  \n▶ Cases▶ Knobs  \n▶ Antenna Components▶ Brackets▶ More….  \n▶ https://www.thingiverse.com/search?q=ham+radio&type=things&sort=relevant&page=1  \n# Two Fundamental Ways to Make\n\nThings  \n▶ Subtractive-Start with a block of something and remove pieces▶ Saw▶ Lathe▶ Mill /CNC  \n▶ Additive-Start with nothing and add pieces▶ Injection Molding▶ 3D Printing  \n# Additive Manufacturing\n\n▶ Injection molding▶ High startup costs▶ Inexpensive unit cost  \n▶ Optimal for large volume manufacturing▶ Low startup costs▶ Higher unit cost▶ Slower manufacturing▶ Optimal for small(ish)manufacturing runs  \n▶ 3D Printing  \n3D Printing in manufacturing  \n# Types of 3D Printing\n\n▶ SLA-Stereo Lithography (i.e.resin)▶ Extremely fine detail (jewelry)▶ Small models▶ Moderately fast▶ Hazardous chemicals  \n▶ FDM-Fused Deposition Modeling (i.e.filament)▶ Fine detail▶ Large models▶ Slow▶ Non toxic  \n# Types of 3D printing (cont)\n\n## ▶ Resin\n\n▶ Expose a resin to UV light to cause it to harden▶ Can use a UV laser to irradiate a bit at a time  \n▶ Can use a UV light source and mask to irradiate a layer at a time▶ Melt a filament and deposit it point by point  \n▶ FDM  \n# Resin Printing\n\nResin Printing  \nProcess  \n▶ Start with a 3D model (.sls file)  \n▶ Use software to slice it into layers and plot the path for the printhead or laser▶ Download file to printer and go","cbCaiudpY7KLZTLf","https://ap.wps.com/l/cbCaiudpY7KLZTLf","pdf",8595841,1,29,"English","en",105,"# 3D Printing:What's It All About?\n# Make Things\n# Two Fundamental Ways to Make\n# Additive Manufacturing\n# Types of 3D Printing\n## ▶ Resin\n## ▶ FDM\n# Types of 3D printing (cont)\n# Resin Printing","[{\"question\":\"What are the two fundamental ways to make things?\",\"answer\":\"The two fundamental ways to make things are subtractive manufacturing, which involves removing material from a larger block, and additive manufacturing, which involves adding material layer by layer.\"},{\"question\":\"What is the difference between SLA and FDM 3D printing?\",\"answer\":\"SLA (Stereolithography) uses UV light to harden resin and is known for extremely fine detail, suitable for small models and jewelry, but involves hazardous chemicals.
