Over the summer, students moving our 3D printers to and from the AggieSTEM summer camp sessions accidentally dropped three 3D Printers into a pit due to on-campus construction they were trying to lift the cart over, resulting in various types of damage to the MakerBot Replicator, RostockMax delta and MendelMax cartesian printers.

 

 

 

In order to prepare to give the free 3D Printing classes for Element14, I began repairing the three printers to get one into operational shape. The first printer to be fully recovered to operational status has been the MendelMax cartesian-format 3D printer based on the Prusa Mendel RepRap design. The first few items were visible as obvious damage to the printer itself - the LCD controller was knocked off, while the bed level probe was crushed, the hob was damaged by impact with a stronger material (the hob was made from brass), while the extruder hotend's nozzle was crushed by impact that closed the 0.4mm aperture.

 

Hob

 

The hob was replaced after my wife's observation of metal debris jamming the grub screw, which was ferrous and wiggled free using strong rare-earth magnets, allowing replacement with a spare hob.

 

e3DHotEnd

 

Because the J-head's nozzle cannot be separately replaced, I was able to obtain an all-metal E3D v5 hotend that was compatible with the J-head's mounting flange with some shimming.

 

MechanicalEndStop

 

Once replaced, the original hall-effect (magnetic) Z axis endstop was revealed to have been damaged as well, but after discussion with the original designer, I was able to replace it with a mechanical endstop using locally-available switches and a simple 3D printed replacement bracket shared with me via Git.

 

BrokenBuildPlate

 

After replacing the endstop, during test of the new extruder's elements, the filament slipped and yanked the spool holder from the top of the machine, shattering the borosilicate glass (Pyrex) build plate. While waiting on the replacement glass, my wife tried to bend the extruder's lower guidler and snapped it in half, revealing an internal break that was flexing as the extruder advanced and allowing filament to twist up in a void created by the broken extruder's guidler bracket being partially hollow.

 

BrokenLowerGuidler

 

Through judicious use of plastic-compatible epoxy, Super Glue and spare washers, I was able to return the printer to basic operation while I designed a thicker lower guidler that includes the shim needed by the v5 E3D hotend and ordered a copy from a 3D Printing service while I waited for the epoxy to harden.

 

GuidelerAndAdjustableTension


After the temporary repair, I was able to create a replacement for the flawed part. Once the new thicker lower guideler was installed together with an adjustable tension adaptation to the spring, I also fabricated a replacement for the upper guideler.

 

UpperGuidler


This allowed easier alignment between the filament and the new extruder hob, while I also reprinted Z axis caps to make everything the same color when I talk about additions to the printer (students noted the previous purple was hard to identify).

 

ZCap


While repairing the more solid extruder guidler components, a washer fell out, rolled the length of the replacement build plate, bounced off the frame and through a tiny slot in the power supply where it bridged 110VAC with the DC supply for the electronic control board, "letting the smoke out" of the chips and requiring a replacement.

 

FanMesh


To prevent further such issues, I sealed all of the power supply's vents using mesh screens for case fans.

 

RAMBOboard


I first tested an Arduino MEGA + RAMPS + Pololu stepper motor controllers, but settled on an alternate RAMBO controller board so that my replacement LCD could connect properly to the alternate bus structure.

 

AutoLevelProbe


After re-wiring the auto bed leveling probe to reflect the board's reversed and poles from a Servo standard connection, I was able to get the new electronics and auto bed level probe re-installed.

 

GLCD


After printing a case and mounting adapter for the GLCD, I was able to get this installed and working together with the 3D Printer so that the printer can operate stand-alone from the SD card without needing the host computer for basic operation.

 

RasPiBModels


Expanding beyond this, my students wanted to install one of the new Raspberry Pi B+ boards configured with OctoPi, WiFi and a Web-cam to allow wireless management and monitoring.

 

OctoPi


After designing and printing a case for the model B+, I was able to get this configured and installed, allowing remote access and control of the original MendelMax. Finally, after many steps, the "mildly damaged" 3D printer was returned to full capacity plus new capabilities and is used in my 3D Printing classes for demonstration of the use of 3D Printers in creating cases for Arduino, RasPi, and other electronics. Now, to get the other printers repaired in turn!

3D printing has brought serious innovation to all industries that rely on manufacturing processes. With electronic production generally being outsourced and not so much under personal control, the oversight and specification of electronics is more-so a take it or leave it kind of market. Customization in hardware is usually expensive, or hard to come by if not and requires some sort of insider connection.

 

With 3D printers and additive manufacturing technologies, there is no doubt that personalization is now more possible than ever. As 3D printing technology is more accessible to individuals and business alike, the capability for an array of people to choose what and how they produce things is ideal for the experienced makers and the novice as well.

 

Graphene is a conductive material that is able to be printed along with plastic, with this ability the sky is the limit. Manufacturing your very own circuit boards, lamps, or even a gaming system is possible for those inclined.

 

3D Printing with Graphene Filament is making waves for us makers, do some research on the topic and find out that there is so much to look forward to in circuitry.

3D printing has rapidly expanded in capability and accessibility not only to businesses but individuals alike.

 

Additive manufacturing technologies are changing the way that things are produced and manufactured. From food to airplane parts 3D printers have taken the manufacturing industry and flipped it on its head.

 

Cubify's 3D printers are no exception to the progressive technology shift that is being seen in publicly accessible and affordable 3d printing technologies. With an interface that gives an ease of use Cubify is friendly for children whether education is what you're seeking, or entertainment is the main goal.

 

Ease of 3D printing is ever becoming more possible. Cubify strives for industry leadership that is unmet by most 3D printer provider.

 

"Getting there is easy with instant-load cartridges. Instant material loading is now easier than changing an ink cartridge. The new non-clog technology and moisture-lock cartridges ensure extended shelf life and total material usage, improving print quality and sustainability. The printer detects material type automatically based on the cartridge, eliminating the need to change print settings. The cartridges are easy to load and store while preserving the life and quality of the materials. Preloaded filament jets and an auto-leveling print pad for 70 micron high-resolution ensure beautiful, effortless prints every time."

 

The Cube 3D Printer for Kids is recommended for children 8+ and meets IEC Home Printer Certification 60953 (TUV). Making this 3D printer a no brainer for parents and teachers alike.

3D printed Saxophone fully assembled. (via Professor Olaf Diegel's ADD Guitars)


Ah, nothing beats the sultry, silky tones of an alto saxophone in the midnight hours.... unless they're playing 'Careless Whisper.' Nonetheless, saxophones can be expensive due to the materials used. Professor Olaf Diegel of

Lund University, in Sweden decided to change that by creating a nylon 3D printed saxophone. While the nylon material may remind you of being forced to play the recorder in grade school, the sound from this sax is far from horrible. In fact, this 3D printed saxophone sounds pretty good. The timbre certainly isn't equal to that of a brass alto saxophone, but it has a decent sound. Judging by the video, it seems to run a bit flat and sound a bit tinny on the higher notes, but that could also be due to poor saxophone playing.

 

I remember when I was learning to play the alto saxophone with a brass sax I got for $150. I could belt out some decent notes, but not consistently and I blamed it on frayed pads. My teacher couldn't tell if it was me or the saxophone, so he lent me his for the day. Well, it was definitely me. Why am I telling you this story? Because I still can't tell whether this 3D printed sax is half decent, or whether Professor Olaf is just a half decent player.

 

In any case, if the cost was low enough, it could be worth using as a practice saxophone. For now, the keys are supported by rubber bands, which is unseemly. But Diegel intends to redesign the print to account for the nylon material. The new design due in a couple of months, according to Diegle, is supposed to address air leak issues and have better pads, not to mention an integrated spring system for the keys. For now, this is simply a testament to what 3D printing can do. Hopefully, the new design will also be able to compensate for the nylon material and produce a deeper, richer sound-. It would probably be impossible to replicate a brass sax, but if constructed well, a nylon sax could produce a sound all-it's-own.

 

Hey, look at The Vegetable Orchestra (which performs on instruments made of fresh vegetables)! There is a time and place for all sorts of kooky instrument variations.
