Manufacturing ESD-safe tools can be extra expensive and time-consuming. Find out how you can produce ESD-safe tools more quickly and affordably in our recent blog post https://t.co/ShIZmI1jup

@CNC_Kitchen @Joel_Driver @MarlinFirmware @BigTreeTech Take a look at the M5 Pro from Smart PID, it’s an amazing value and works great for these kinds of projects. https://t.co/L07wQ1dRhb

@schild0r @CNC_Kitchen Annealed PET-CF would be a better choice for this part. Long term heat resistance up to 155C (205C for lighter loads) after annealing.

@CNC_Kitchen @schild0r Fiber reinforced amorphous thermoplastics generally have similar creep performance as their unfilled counterparts, go above the Tg and it will rapidly deform. Semicrystalline polymers benefit from fiber reinforcement and have much better creep performance above Tg.

@harvardmed @jrsoucy @HMSeye Look at you @jrsoucy I see that Trudge hat!

@thejackbeyer @NASASpaceflight That’s an expensive firework! 💥🎇

[Charles B Sweeney @sweenzorrr]

@VisionMiner Let’s get some PCTG and HTN-CF25 on there!

@SliceEngineer Great white paper!

[RAPID + TCT Event @RAPID_Event]

We’re proud to have @Essentium3D at RAPID + TCT this year! Essentium will be at booth E7625 & they will be showcasing the world’s first industrial 3D printer with independent dual extruders – the HSE™ 280i HT. Attend RAPID + TCT to see more. https://t.co/VS7PLkDtLa

@BigRep Also might want to check your math. -55C dew point at 25C is 0.11% humidity, not 0.01%…

We are thrilled to announce we have signed an LOI to acquire Collider!

@Mobile_Dom @3dpNero @CNC_Kitchen @toms3dp Makes PP more printable with less warp. Stiffer and stronger. Primary use cases: low cost highly chemical resistant, and low surface energy material for low pressure molding with good release properties.

@BigRep How do you see what filament is inside?

Essentium Acquires Collider & its Hybrid DLP 3D Printing Technology https://t.co/Fu7qinuuY5 #3DPrinting #Business

[Charles B Sweeney @sweenzorrr]

@MicahJGreen I think the real questions are: 1) is it single layer or multilayer GO and 2) what aspect ratio/particle size distribution. Maybe Pfizer cracked the code on high quality low cost GO production. Hummers method is a pain!

[Vision Miner @VisionMiner]

PA-CF from Essentium with a Perfect First Layer using Nano Polymer Adhesive👌Printed on the Funmat HT, All Available on our Website 🧐💪🧵

@SliceEngineer Also check out the overmolded microfit 3 cables, very convenient and reliable.
