Your Finished Model well kind of finished Built

Your Finished Model! (well. . . kind of finished) Built Models often require love and care after printing to really make shine. 1. Removing supports and struts 2. Smoothing and polishing 3. Gluing and assembling 4. Painting and sealing

Removing Supports and Struts – Dissolvable Filaments

Removing Supports and Struts – Dissolvable Filaments HIPS (High Impact Polystyrene) and Dissolving in Limolene • Probably the most common dissolvable support material • Limolene is a fruit-based oil • Use a glass jar or chemical container • Follow use and disposal instructions • Can make your plastic more brittle

Removing Supports and Struts – Dissolvable Filaments PVA (Poly Vinyl Alcohol) and Dissolving in Water • Water based support filament type • Relatively new material for 3 d printing • Needs to be stored in a very dry location! • Warm water that is replaced regularly • Use a glass or plastic container

Removing Supports and Struts – Dissolvable Filaments Proprietary Solutions • What is it? What’s in it? How does it work? • Usually tailored specifically for each 3 d printer type • Can be more expensive, but generally work with little or no trouble

Removing Supports and Struts – Dissolvable Filaments What is This? ? Wave. Wash 55 Stratysus’ most compact support removal system. It lets you quickly remove support material without tedious cleaning, by simply dissolving it away in a water-based solution.

Removing Supports and Struts Supports made using the same material as the actual model

Removing Supports and Struts Just a reminder, your support settings can dramatically change how easy or difficult this step is!

Removing Supports and Struts • Start with the low hanging fruit! • Peel away the bottom and the easily accessible areas. • Be careful to support the model when cracking away supports so as not to delaminate layers

Removing Supports and Struts • Pull away remaining chunks • With needle nose pliers clear away nooks and crannies with x-acto blade (CAREFUL)

Removing Supports and Struts • Sand at your own risk. . . • Mixed results • Reduced color clarity (white)

Smoothing and Polishing What if you want your model to look, like, really cool?

Smoothing and Polishing ABS Plastics will smooth/dissolve with acetone

Smoothing and Polishing Now. . . you can sand. Sanding Bead Blasting / Sand blasting Dremel

Smoothing and Polishing To Start with. . . Keep it Simple! – Simple Acetone Jar • Clean off and sand part • Fill up a glass or chemical container with a half inch of acetone • Uncap the jar to expose the acetone to air (do in a well ventilated area!) • If possible, slightly heat the jar – suggested to about 100°C • Lower or hang the model in the jar for 5 -15 minutes (rotate if necessary) https: //www. youtube. com/watch? v=Xj 53 P 2 Yz. YGM

Smoothing and Polishing Getting Fancier and Bolder – Heated Dip • Deep fryer / slow cooker • Dipping works MUCH faster but can give a more even finish • Caution with all these home-made approaches!

Smoothing and Polishing Insanely Fancy – Evaporation System • More work! • Might become commercial product http: //www. 3 dprinterworld. com/ article/smooth-like-butter-mass-finishing -for-abs-and-pla-prints-magicbox

Gluing and Assembling Complex shapes and parts can be built separately and assembled

Gluing and Assembling Basic Cyanoacrylate Glues Work. . . usually

Gluing and Assembling Don’t like holding things for 20 minutes while they dry?

Gluing and Assembling Using Acetone to Fuse ABS Plastic Parts

Gluing and Assembling For those fancy rubber or Ninja Flex Parts

Gluing and Assembling The Sky is the Limit • Adhesive (cyanoacrylate) • Adhesive (silicone) • Solvent (acetone) • Adhesive (epoxy) • Hot air plastic welding • Ultrasonic spot welding • Fasteners (mechanical)
