BASF Ultrafuse 316L - Workflow

June 22, 2020

This blog post will cover the logistics and steps of how you go from 3D printing Ultrafuse 316L to having a stainless part in your hands. Please read the steps carefully. 

The workflow is fairly simple:

  1. 3D print the green part
  2. Package it
  3. Send it out to DSH for debinding and sintering (D&S)
  4. Wait for the sintered stainless part to arrive back

 

It is best to send parts in batches or increments of 1kg. Each coupon for D&S is for 1kg. Note that if your green parts weight 1.1kg, you will need to purchase two coupons, and if your parts weight 0.5kg, you will still be charged the full 1kg price. 

Here is a detailed step by step guide:

Step 1: Make sure you understand the limitations of 316L by reading the design guidelines here. Not everything that can be 3D printed will post-process. If you are still not sure, contact our team. 

Step 2: Once the design has been checked, go ahead and 3D print it. Printing guidelines here. Pay close attention to the part scaling factors.

Make sure to record the following parameters for every single part:

  • Maximum wall thickness
  • Infill %

These parameters are crucial for DSH to set the correct debinding and sintering time.

Step 3: Fill in the work order (if you haven't received this document when you purchased the filament, please contact us) and print two copies, one goes inside the box, and the other goes outside of the box.

Step 4: Weigh all of your parts before packaging and record that number

Step 5: Wrap each of your parts individually and once in the box, ensure that the parts do not shake as the parts are brittle in their green state. 

  • Do not let the parts rattle in their shipping container
  • Do not let the parts rub against one another or their packaging

At this point, you can ship the parts directly to DSH if you have a FedEx account. You'll need to purchase a D&S coupon here. 

If you don't have a FedEx account, continue reading.

Step 6: Send or drop off the package at Shop3D. We will aggregate a specific amount of parts and send them out to DSH for you. If this is the method you are going with, please take a look at this product instead of the regular DSH coupon

Step 7: Wait for your parts to arrive back! 

Leadtimes

  • Parts must arrive the Friday before the D&S day
  • DSH Tech processes parts twice a month on the 2nd and 4th Tuesday of every month. 
    • Parts will ship out on the Friday of the same week.
