Many people are scared to try this… and I want to help you succeed.\u003c\/p\u003e\u003cp\u003eSupport Magic is a 3D model that has multiple different tests and is designed to be used with mixed-material supports. A typical example is the PLA\/PETG combination, although many others are possible. Such “breakaway” supports offer typically excellent finish quality because of the dissimilar materials, and the fact that you can print with no Z-gap.\u003c\/p\u003e\u003cp\u003eSupport Magic tests the quality of your support material setup between the two materials by testing the removal, durability, and surface finish of each section. Support Magic can help you achieve perfect supports with easy removal and without scarring for your 3D printing projects.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003ci\u003eBambu Slicer Users:\u003c\/i\u003e\u003c\/p\u003e\u003cp\u003eI've done the settings work for you for a good print already.

Bambu Slicer and Orca Slicer are good examples.

For example, if printing the model in PLA, and interface in PETG, your settings should look like this:\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/li\u003e\n\u003cli\u003eFor PLA\/PETG, in particular, to avoid extruder jams:\u003col\u003e\n\u003cli\u003eSet the bed to the lowest temperature you can afford with good adhesion (~65-70). This will minimize jamming, particularly with PLA supports for PETG prints.\u003c\/li\u003e\n\u003cli\u003eIf your printer is enclosed, open the doors and\/or vent the top of the printer by taking the top off (for Bambu printers).\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003c\/li\u003e\n\u003cli\u003eMultiple different styles of support work fine, but the I find that Paint-on supports, with Normal (not tree) and “Snug” style often work well.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA note on purge volumes \u0026amp; strength\u003c\/strong\u003e: Lower purge volumes can cause issues with layer adhesion, particularly when switching back to the main model filament. Accordingly, you may wish to increase the purge volume when switching back to the \"main\" (model) filament from the support interface filament. This will ensure you've got rid of most of the other filament and will have strong layer bonding. My profiles here have left defaults.. but some people suggest you may wish to use numbers as high as 600-700 if you are concerned about the next layer's Z-bonding strength. For example, if your main filament were black w\/ green PETG as support, you might set the matrix like this:\u003c\/li\u003e\n\u003c\/ol\u003e\u003cfigure class=\"image image_resized image-style-align-center\" style=\"width: 44.61%\"\u003e\u003cimg src=\"https:\/\/makerworld.bblmw.com\/makerworld\/model\/DSM00000000036554\/design\/5e336a62-b018-4317-a3b5-7d2a54dc8f47.png\"\u003e\u003c\/figure\u003e\u003cp\u003eDesign by Adam L on MakerWorld (license: BY-SA).\u003c\/p\u003e","brand":"Mymadmanlab","offers":[{"title":"Default Title","offer_id":67398332383536,"sku":null,"price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/0809\/5280\/files\/0_d0971bb2-e8f0-45d5-ba8e-947d1a294b2e.png?v=1784882237","url":"https:\/\/mymadmanlab.com\/products\/support-magic-a-support-test-for-mixed-materials","provider":"Mymadmanlab.com","version":"1.0","type":"link"}
