Prusa Releasing In-House 3D Printing Filament

Fresh off the multi-material upgrade for its Prusa i3 MK3/MK2.5, Prusa has more good news – this week, the company released its new filament, Prusament, which is made entirely in-house. CEO and Founder, Josef Průša, said that the company was not happy with the over-exaggerated quality and specs that “most filament companies claim but don’t deliver,” which continued to cause its users to have issues poor print quality and jams.

“So we built a factory and just started to sell our own filament,” Průša told 3DPrint.com. “It took us over a year but we have something pretty special. We guarantee 20µm precision and every spool is traceable on our website, where you can see the full inspection report. I believe we are the only one to do this and hope to set a precedent.”

Check out the sample spool of Prusament for yourself – you’ll see that Prusa isn’t messing around.

Cincinnati Incorporated Launches New Carbon Fiber Material

Cincinnati Incorporated has developed a new material for its SAAM that is ideal for custom tooling and fixture applications. The carbon fiber resin creates a high strength-to-weight ratio and superior surface finishes.

Another company with a new 3D printing material launch this week is Cincinnati Incorporated (CI) – it just released a new carbon fiber resin material for its SAAM (Small Area Additive Manufacturing) 3D printing system. Because it’s been reinforced with carbon fiber, the lightweight, impact-resistant material is durable, stiff, and has low warping, along with accurate parts featuring advanced inter-layer adhesion results. It also has excellent surface finish, making it a good choice for applications in assembly, CMM, CNC fixtures, custom tooling, and has a very high strength-to-weight ratio.

 

 

 

Morgan Motor Company Turns to Stratasys 3D Printing for Prototyping

Family-owned British motor car manufacturer Morgan Motor Company is no stranger to 3D printing, and recently turned to the technology again for help with prototyping on the factory floor. In order to get rid of the endless talks with suppliers and lower the time to market, the company, which manufactures roughly 1,000 vehicles per year, invested in a Stratasys Fortus 250mc from Tri-Tech 3D, a Stratasys reseller in the UK.

“Since the introduction of 3D printing, using the Stratasys Fortus 250mc, Morgan have been able to try more daring designs within research and development,” said Tom Morris, a CAD technician with Morgan Motor Company. “It’s given us the opportunity to take these designs, trial them early on, giving us physical samples, which essentially cuts out the whole quoting process of liaising with suppliers, delivering these parts back to Morgan. Morgan are a low volume vehicle manufacturer, so the ability to be able to design parts on CAD, 3D print them, and take them to the shop floor at a very quick rate is vital to our success as a business.”

Fixing Nintendo 64 Joystick with Reverse Engineering and 3D Printing

California Polytechnic (Cal Poly) student and retro video gaming fan Nam Le was tired of having to find replacement controller joysticks for Nintendo 64 systems – a common problem many Nintendo fans have dealt with. So he took matters into his own hands, and contacted 3D Hubs for help fixing the problem. Le ended up reverse engineering the nearly 20-year-old components, 3D printing them, and redesigning the entire joystick system. It took him three months to disassemble the original controller, measure the components, and design them in CAD – a very impressive task, as he’d only ever taken a basic 3D modeling introduction class.

He determined that the joystick’s whole assembly would wear down over time, causing part failure, and designed the new components so that they were very sturdy and easy to replace. Le 3D printed the gear teeth and housing with Visijet M3 Crystal material, and 3D Hubs manufactured his redesigned joystick out of Nylon PA12 material on an HP Multi Jet Fusion 3D printer.

“Generally, harder materials won’t be worn by materials of a lower hardness,” Le explained about his material choice. “The result is having only one part wear compared to every old component wearing. Every once in a while the stick will have to be replaced, but it takes a longer time to wear and is a better cheap alternative than buying a new controller.”

Six months in, Le’s 3D printed prototype joystick controller shows no signs of breaking.

3D Print with Five Materials with New Prusa Upgrade, Plus More New Features

One of the reasons that Prusa has so many fans is that it is constantly working to improve and update its products. One especially popular upgrade in the past couple of years was the multi-material upgrade for the Prusa i3 MK2 3D printer. According to a customer survey, more than 73% of respondents would recommend the multi-material upgrade to friends or relatives, but as Prusa founder Josef Prusa says in a blog, the company wanted to improve the feature further and so redesigned the unit completely, making it simpler and more efficient. They also added an automated filament-cutting blade and physical buttons for manual controls.

The new hardware also features a direct drive, a single extruder motor, and print recovery – and it can print with five materials, instead of four.

“What we have here is a one-of-a-kind multi-material printing addon that is fully integrated with the printer, so everything is perfectly synchronized and the whole thing works seamlessly as a single unit,” Prusa says. “It’s just like printing on the standard MK3 – slice the model, export the G-Code, put it on an SD card and you can start printing right away without any hassle.”

The Multi-Material Upgrade 2.0 can be ordered for $299, with shipping anticipated in November.

New firmware 3.4.0 for the Original Prusa i3 MK3 and MK2.5 has also been released. One of the biggest new features for the MK3 is a filament sensor, allowing for auto-loading, stuck filament detection or pausing the print when material runs out.

“Now, the part of the software responsible for analyzing the filament flow has been completely rewritten to improve the precision and reliability of the sensor,” Prusa says. “It means that the sensor can recognize filament runout with greater accuracy and the number of false detections drops significantly. In the past, MK3 and MK2.5 printers shared the same values for the evaluation process, which sometimes led to incorrect results. Firmware 3.4.0 fixes this issue.”

Another improved feature for the MK3 is more reliable power panic/blackout protection. In addition, users can now choose from four beeper options: loud, for failure and user input notifications; once, which is the same as loud but beeps are played only once; silent, which is only error notifications, and mute, which is completely silent, no matter how serious the error is.

“To decrease the load on the printer’s CPU, we have introduced further optimizations for feedrate and acceleration values,” Prusa adds. “Up until now, the feedrate and acc values were compared to hardcoded limits with every movement throughout the entire print. In the new firmware, the checks for G-codes M201 and M203 are performed only at the beginning of the print. If the input values are smaller than hardcoded values, no action is triggered. In case the values from G-code are greater, the firmware replaces them with the default (hardcoded) ones.”

M-84 G-code is also available. The code can write or read a pin on the mainboard, which can be used to trigger a camera’s shutter so that users can create timelapses of their prints.

Several minor tweaks and bug fixes have been made to the new firmware as well, and you can read about it in more detail here.

Prusa will be in attendance at World Maker Faire, which is taking place in New York on September 22nd and 23rd.
