Here’s data from differential scanning calorimetry (DSC) for ABS and PETG. These are amorphous plastics with no true melting point – they just gradually get less viscous with temperature. That’s one reason they are so much harder to use

Expand your 3D Printer creation sizes (beyond your print-bed) with a technology I invented!

I invented a modular interlocking element technology. I like to call them, Extruded Elements. (U.S. Patent Pending)Overview-https://youtu.be/jX-aoQJb2-M(Jump to 4:38 in the youtube video to see my Stand-Up Paddle Board I’m 3D Printing)​Dad’s Bust & Extruded Element Examples (left); 1/3 of Stand-up Paddle Board (right)​I am sharing the ability to create with Extruded Elements free for non-commercial and personal use.​To make prints larger than your print bed or simply create extruded elements…You need-OpenSCAD (https://ift.tt/2OjKsIM Extruded Element Library from EELCC’s gethub repository (https://ift.tt/2In7s41 can simply download or paste the text from eellc_lib into OpenSCAD and press F6 to render your first Extruded Elements.​Head over to r/ExtrudedElement to share your creations, ask questions, and share ideas…​Extruded Element Videos for workflow and instructions-Workflow-https://youtu.be/ZQWPYnA3EcgInstructions-https://youtu.be/LaUyAL2Gcfg​​Check out my ongoing personal projects using Extruded Elements:- Stand-up Paddle (SUP) Board4’ of 12.5’ final length complete (currently @ ~500 total hours of print time)See through for aquatic observationCarbon fiber face sheets for high pressure regionsCould be accomplished with 150 feet of extrusion length (vs. > 1500 hrs of Print time))- Bust Sculpture Up-scalingDigital editing in progressPlanned for Black and Carbon color filamentscaling from sculpture (~0.5 X Human Head)…to 1.5 X human head via Photogrammetry(18″ Tall from Tip-of-Head to Tip-of-Chin)​Check out full details on http://www.extrudedelement.com/​​Edit – Bulletized numbering was off.Edit 2 – Numbering changed to “-” after double-fail.​ https://ift.tt/2zDzw09

Interesting little bit of material science explaining the difference between PLA and PLA+. My theory is that PLA+ contains a second polymer besides PLA to change crystallization behavior. Description in comments!
