ARQQ Heat Bed Mosfet Tube Hot Bed Power Module Expansion for 3D Printer Heating Bed Accessories(Pack of 2)

Details: Dimensions: 60*50mm
Net Weight: 40g
Color:Black
Max Current: 25A(Enhance heat dissipation)
Wire’s color is random

Summary:
1. Remove basically all ouside screws for your anet a8 control box
2. Take pictures of existing board wiring
3. Unscrew two large 12/14GA wires on the board labeled “hot bed”
4. Screw these two wires into the new mosfet board labled “hot bed”
5. Connect the small jumper wires (white) to the control board where you just removed the two wires and screw them down. Note the polarity on each board. Match (+) to (+) and (-) to (-)
6. FInd 2x 6-8″ pieces of 12 or 14 AWG wire. Most cheap extension cords are 16AWG (too thin). Your local home depot / menards / ace will have this as cut-to-length
7. Run one of the 6″ wires to the power supply (+), screw in; and the other side to the (+) DC IN on the new mosfet board. Repeat for the negative wire (-) to (-)
8. Many people use velcro to secure the new board to the top of the control box. Others print off a holder from thingiverse
9. Put everything back together
10. When complete, you’ll see a blue light activate for signal from inside the box when the bed heater is activated by the control board

Package Included:
2xHot bed MOS Tube Power Module Expansion

Product Features

  • Work with anet a8 3d printer heat bed
  • Completely solve the hot bed power is too large and the load current issue
  • Under the premise of normal cooling, it work stable under I(Max)=25A, the current must not exceed 25A while the process working
  • General Add-on Heated Bed Power Expansion Module
  • Note: Any issue please contact us before, we will always here to help!

Stainless steel takes the heat off difluoromethylation

Continuous flow difluoromethylation with fluoroform

Researchers have 3D-printed a flow reactor out of stainless steel for performing a rapid exothermic reaction that turns a Teflon waste product into a synthetic building block.1

Led by Oliver Kappe at the University of Graz in Austria, the team made the metal reactor specifically to convert a known batch reaction – the difluoromethylation of a lithiated nitrile2 – to a scalable continuous process.

Fluoroform is a large-volume waste product from the production of fluoropolymers such as Teflon. While nontoxic and ozone-friendly, it’s also a greenhouse gas 11700 times more potent than CO2. Overcoming its very low reactivity for large-scale use in organic synthesis would reduce waste and pollution, but this requires harsh reaction conditions incompatible with polymer resins previously used to print bespoke reactors.

Instead, the team combined the flexibility of 3D printing with the high thermal conductivity of steel to make a flow reactor for a multistep nitrile lithiation and difluoromethylation with gaseous fluoroform. Including a cooling element in the reactor design made it possible to perform the process at cryogenic temperatures.
