Where to find information on 'fast' or 'professional' 3D printers?

I work for a company that makes items from plastics. Many or our current runs are between 500 and 5000 copies, but knowing the company, if we find a good method to do smaller runs, they are willing to see if it is a good commercial option. At the…

Are 3D printed gears applicable for industrial use?

Are 3D printed gears applicable for industrial use? I want to print some gears with ABS. What will their lifespan be? How long will they last if I use them, for example, every day?

What type of fire alarm/smoke alarm should my printer have?

I know you should, like an infant, never leave your printer without surveillance. But sometimes we all do, trusting our double thermistors and heat runaway configurations. But electronics fry and who says there is no danger even after the print job…

How do you assure that you print layers that bond correctly?

I'm fairly new to 3D printing but I'm getting the steam up and I chug out pieces without much hassle. One thing though is that I have the impression that sometimes, parts are easily broken, and I suspect bad adhesion between layers. I'm printing…

Are there any methods of limiting exposure of hazardous fumes and odors emitted by heating the plastics?

When using thermoplastic-filament, this can be potentially hazardous, since constant printing can emit hazardous fumes and odors that may be emitted by heating the plastics. I understand it normally should be used in well ventilated areas. However I…

Small part bed adhesion

I am trying to print a model that has (at the start of the print) several small parts attached to the bed. Some of these parts have bed contact 2.5mm x 20mm. After a few layers, if there are any imperfections in the previous layer, the hotend is…

missing small sections of layers after a retraction

So I am missing small sections of a layer when it prints, after a retraction for a layer change or a move, the extruder stops moving (no it isn't clicking or anything else. Just not moving). Which is fine for a few millimeters because the pressure…

Managing LEDs with NanoDLP

I'm building my own DLP printer with UV LEDs. I use a 20A relay to power them on, since they require high power and can't be directly driven by arduino or Raspberry. I'm planning to use them with NanoDLP on Raspberry + GRBL on Arduino. Is it…

Raise3D Wi-Fi Protocol

I am interesting in connecting my RepRap printer to ideaMaker using the same Wi-Fi protocol they use for their Raise3D printers. I am sure I could emulate it using a Raspberry Pi if I knew the format of the protocol (I suspect it is pretty…

How do people load filament, prime the printhead, flush out the old filament when changing colors when using a standalone 3D printer?

I am wondering how people that use standalone 3D printers (printers that have the ability to print autonomously from SD Card) feed in filament, prime the printhead and/or change filaments without a laptop ? Do the printers have a menu to arrange all…
