Questions tagged [heated-bed]

Use this tag for questions about the Heated Build Platform or Plate (HBP) for 3D printers.

A Heated Build Platform (or Plate) is an additional piece of hardware that provides an additional heating element in the build platform. It is a required piece of hardware for plastic filaments that shrink considerably. As the extruded plastic cools, it shrinks, and when unevenly cooled down because of the geometry of the print, it can result in a warped part lifting from the platform. At elevated temperature, shrinkage is less and more evenly when the bed temperature is close to the glass temperature of the plastic resulting in higher quality prints.

Why do the corners of my ABS object lift off the bed?

I print ABS on a LulzBot Taz 5 and frequently have issues with the corners of objects lifting off the bed. My extruder is at 230 °C and the bed is at 90 °C for the first layer and 100 °C for the rest of the layers. I have experimented with using ABS…

Ideal print bed: Glass or Aluminium?

Glass is always level, easy to clean, easy to work with. Aluminium allows for the addition of automatic bed leveling with an inductive sensor and distributes heat a little more evenly. When printing mostly ABS and PLA, which one is better?

Why keep the bed heated after initial layer(s) with PLA (or PETG)?

I'm printing on an Ender 5 with the default flex/magnetic build surface. I read that PLA and PETG may sometimes be printed without any bed heating at all and also that bed heating is the main contributor to the power consumption of a printer. As I…

Using dollar-store picture glass for print bed on top of original heated aluminum bed?

I'm having a really hard time printing on my aluminum heated bed... Cleaning it just results in it being scratched (trying to scrape dried hairspray/glue/etc off) and I don't think it is particularly flat either. I was thinking of stopping by the…

My heated glass print bed keeps chipping and cracking. How can I prevent this?

My thermoplastic FDM printer has a heated bed and uses glass as the printing surface. Sometimes the glass will chip or break entirely when I'm removing my print. This happens most often when the print has a large area in contact with the glass. What…

Heated bed - what are the benefits? Why use one?

When using a heated bed with your printer, I have seen claims of running temperatures of 90c throughout the print. That seems like a fairly high power use to keep a large slab of, say, aluminium at 90c for long print times (ie multiple hours). Is…

How to center my prints on the build platform? (Re-calibrate homing offset)

When I print large prints close to (but not exceeding) the maximum dimensions of the heated build platform on my Anet A8, the brim or skirt or the print itself is printed outside the heated bed, while there is some space left at the opposite sites.…

PLA and bed heating?

I've read different things about PLA and heat-bed. Some say it is not needed, others recommend 60-70°C, but not for the first layers. For larger objects I often have the problem that the object does not stick to the blue-painters-tape-covered…

Why doesn't PLA stick to heated bed?

I have a basic Creality Ender-3 with a black rough bed cover. I'm printing with PLA. After assembly, I printed 3 or 4 small toys sliced by Cura with basic settings. All were printed very well! However, after that, extruded filament would not stick…

Can a heatbed PCB (Prusa Mk2) be straightened out?

I have a really bent heatbed PCB, the middle is elevated about 3 mm with respect to all edges. I have found this thread Warped PCBs, where a heating method is applied by baking a PCB in the oven, as described here: 3.2 Bow and Twist Repair. Can this…

Clamps / clips for glass on heatbed

I'm looking for clamps to fix the glass on my heatbed. After some search I found that some people use clamps printed of PLA. Can I use PLA clamps for a heated heatbed (~60 °C)? I also tried foldback clips but they block my nozzle. The Anet A8…

How do skirts aid print bed adhesion?

In cura one of the options under "build plate adhesion" is "skirt", which seems to simply print a loop around, but not touching, my print. How is this supposed to help my prints stick to the bed?

Issue with weird heated bed temperature fluctuations

I have a strange issue with my heated bed. It has been working well for a long time, but recently it has developed an issue where the temperature reported by the thermistor will occasionally jump by around 10 degrees. My setup is a 600W, 240V…

Why is a heated bed important?

I hear that heated beds can help with removing finished prints, but not all printers have them! Is this a nice to have or must have feature? Are there any downsides to heated beds?

What is the power consumption of the heatbed and hotend?

What is the power consumption of your heatbed (size) and hotend (model)? I want to verify that it is possible to use a battery to power them.
