Dummies Guide To Miniature Radial Ball Bearings And Their Types

Published on in Category Basics

In this article we will see in details about the roller/radial bearings, and its types and dimensions. Parts in Bearing ##Seals and Shields To help retain bearing lubrication and prevent contamination from the environment a seal (contact) or shield (non-contact) can be employed. Often no seal (Open) is required when the bearing will be housed and externally lubricated or when operated in a vacuum. Seal Identification Type Symbol Properties Cost Description Shield Z They have fair dust resistance and poor water resistance.


Troubleshooting PLA Jamming in All Metal Hotend

Published on in Category 3DPriting

PLA Jamming happens in any all metal hotend, even with E3D, Prusa Nozzle, Printrbot Metal Hotend, etc,. PLA jamming in all metal hot end is common issue, but this does not happen with PEEK based JHead Hotends. Metal Hotend can print High temperatures filaments without any problem, this includes high temperature filaments like ABS, Nylon, Ninja Flex, etc., Here we try to list down the most command reason for jamming and solutions for the same.

3D Printer Extruder Troubleshooting Guide

Published on in Category 3DPriting

In this guide we will list down the most commonly known issue with extruder and their solutions. Extruder Skipping Steps Extruder starts skipping steps or tick tick sound comes from extruder, then try one of this to solve the issue. Check #1: If this issue occurs only in the first layer few layers? Solution: Hotend Nozzle very close to the print bed, offset 0.1 mm or more Check #2: Check the hotend temperature


Top Reasons Filament Jams During 3D Printing

Published on in Category 3DPriting

There are many reason for the filament jam to occur, the effect of filament jam during large print is the worst. In this article let us examine the most common reason for the filament jam and their solution. Active Cooling Solution: All Metal hotends will need active cooling system, like mini Fan or. Without active cooling the heat at the nozzle creeps up to and filament is starting to soften prior to getting to the hotend chamber.


How to dehydrate PLA Filament

Published on in Category 3DPriting

After 6 or more months, PLA Filaments become brittle and break easy. This make the filament not suitable for use. In our observation we found it happens irrespective of your region/climate or manufacture. Only the time may wary based on atmospheric parameters of the place where the filaments are stored. The main reason for brittleness of filament is due to moisture absorption. ABS, PLA, and other common filament materials are mildly hygroscopic, so they will readily absorb moisture from the air.

How To Store PLA Filament

Published on in Category 3DPriting

PLA filament is a bio-plastic, it is susceptible to moisture. As the filament starts attracting moisture, That moisture can attract dirt and dust and spool it right into your print head The filament can expand and jam the head It can become brittle and broken like glass So it is best idea keep the PLA filament as airtight as possible. Thingiverse user and 3D printing enthusiast, Stephen Hall responded to this storage challenge by creating an airtight filament deliver system which is little more than a plastic storage bin (he used the Lock & Lock Handy Rectangular 12ltr container from Amazon), some 5mm push fit connectors, and some 3D printed holders he designed for the connectors.


How to reduce 3D printing time and material

Published on in Category 3DPriting

Unlike 2D printing 3D Printing is a time consuming. A slicer can be configured in such a way that it will fill less in each layer, thus speeding up the print and using less filament. In this article we will see how to speed up thing when using Slic3r for slicing. Fill density Fill density under Infill is the one which controls the layers density. Value Range: This value range for Fill density is 0.


Cleaning blocked extruder nozzle in 3D printers

Published on in Category 3DPriting

Many of you don’t like the nozzle clogs and blocks, We too. Even the smallest contamination can block the 0.4mm nozzle, You can use a 0.4mm or smaller drill bits to clean up the aperture while the hotend is hot. But sometime (many time) the contamination would come back and block the nozzle. That’s very bad especially when your are in the mid of big prints. Nozzle block or clogs can identified via below symptoms, - filament are not extruding uniformly - extrude very thin filament than usual - Or the filament is not at all coming out from nozzle.
