v4.6

Minor Versionm

by Isaac Loux Rattey

Introduction

Main Objectives:

  • Learn about RPL processes and gain an understanding of the research machines
  • Receive RPL staff contacts to expand your network
  • Gain awareness of post-processing parts from different printers
  • Learn about the RPL structure and positional needs
  • Receive hands on knowledge of SLS and a sample part
  • Receive knowledge of the Nanoscribe

Ask questions if you don't know something!

  1. Fire alarms are outside Fire extinguishers are inside Location of the first aid kit
    • Fire alarms are outside

    • Fire extinguishers are inside

    • Location of the first aid kit

    • Dangers of Nylon and Inconel powder

    • You must wear a PAPR when working with the ProX

    • Stay out of the area marked with caution tape when someone is using the ProX

    • You must use the ProX vacuum when working with Inconel powder

    • Nylon powder is less dangerous, but you are required to use a mask and gloves when working with the Fuse

  2. Learn how the Nanoscribe works Two-Photon Polymerization printer which uses microscope objectives to selectively cure resin
    • Learn how the Nanoscribe works

    • Two-Photon Polymerization printer which uses microscope objectives to selectively cure resin

    • These violins are 30 um long. A human hair is approximately 70 um wide

    • View some example Nanoscribe prints using the Jeweler's lens

    • Large Testudo

    • Eiffel Tower

    • Make sure to wear gloves anytime you are in the Nanoscribe room. All surfaces could be contaminated with resin

  3. Learn how the Fuse 1 works Two parts: Printing and Post-processing The Fuse uses Selective Laser Sintering (SLS) and prints in Nylon powder
    • Learn how the Fuse 1 works

    • Two parts: Printing and Post-processing

    • The Fuse uses Selective Laser Sintering (SLS) and prints in Nylon powder

    • The printer lays down a thin layer of Nylon powder and uses a laser to sinter (melt) the powder together

    • The un-sintered powder supports the parts as they are printed so there is no need for supports

    • The Fuse is great for rapid, cheap prototyping

    • Make sure you wear a mask and gloves when working with the Fuse to avoid contact with Nylon powder

  4. Learn how the ProX works Uses Direct Metal Printing (DMP) technology. Similar to how the Fuse prints Very high accuracy and precision
    • Learn how the ProX works

    • Uses Direct Metal Printing (DMP) technology. Similar to how the Fuse prints

    • Very high accuracy and precision

    • Prints in Inconel

    • Wear a mask when working with the ProX, and be mindful of the caution tape on the floor

    • The caution tape shows the area that could be contaminated with Inconel powder

  5. Learn how the Taz works
    • Learn how the Taz works

    • The Taz is a traditional Fused Filament Fabrication (FFF) printer

    • Our Taz is fitted to print using Virtual Foundry Filamet, which is a combination of plastic and metal powder

    • This allows the Taz to print parts just like any other traditional 3D printer

    • Then, the parts can be baked in a furnace to cook off the plastic and product a fully dense metal part

    • Good for cheap, metal printing

  6. Learn about general LM responsibilities and expectations
    • Learn about general LM responsibilities and expectations

    • Lab Managers will be trained on all machinery in the lab and will help assist in completing customer/researcher requests. They will have the ability to focus their job on one of three tracks as a potential replacement for the Powder SME, Nanoscribe SME, or RPL LC.

    • Lab Managers are also assigned specific projects throughout and work on a personal design project throughout the semester.

    • The RPL LC is in charge of keeping the lab operational, ordering consumables for the lab/machinery, attending TW LC meetings, initial POC for external research, and scheduling employees.

    • The SMEs are in charge of keeping the machines operational, working with customers/research to provide the highest level of consultation, as well as training new employees and researchers on the machines.

    • Learn about the structure/hierarchy of the RPL

    • The RPL is different from other labs in that the LC and SMEs are on the same level and share many responsibilities

    • Learn about the RPL team members and receive contact information for future interest/questions

  7. RPL Lab Managers have the opportunity to use free time during their shifts to work on a personal project that they find interesting. Throughout the semester, they can prototype and iterate their design on the Fuse
    • RPL Lab Managers have the opportunity to use free time during their shifts to work on a personal project that they find interesting.

    • Throughout the semester, they can prototype and iterate their design on the Fuse

    • They may print their design in Inconel once they have finished designing it

  8. Post Process your part using the Sift and Bead Blaster Bring your part to your PDM
    • Post Process your part using the Sift and Bead Blaster

    • Bring your part to your PDM

  9. Get a brief introduction to the printers in the RPL Learn about the hierarchy of the RPL and how it is different from other Terrapin Works labs Learn about the design project that RPL staff work on
    • Get a brief introduction to the printers in the RPL

    • Learn about the hierarchy of the RPL and how it is different from other Terrapin Works labs

    • Learn about the design project that RPL staff work on

    • Get some hands on experience post-processing Fuse parts
