How To Succeed with OBC 3D Printing Filament

From Dow Chemical, OBC combines versatile and inflexible into one distinctive materials with properties of each.

OBC 3D printing filament is a breakthrough 3D printing materials from the chemists at Dow Chemical. Designed for high-performance 3D printing, OBC is constituted of a singular polyethylene-based mix that brings polyolefin materials properties to 3D printing. By mixing these two collectively, not solely does it have wonderful dimensional stability and superior chemical resistance, it extremely straightforward to print and its light-weight. Step into a brand new world of expanded capabilities for 3D printing supplies with OBC.

Let’s break it down-

Let’s break it down.


OBC stands for Olefin Block Copolymer, which is an uncommon materials throughout the world of 3D printing. It’s a proprietary mix of plastics that makes OBC straightforward to print and grants it some chemical resistance and suppleness. This mix has very low density with out sacrificing energy and toughness. Density will get difficult with regards to filament that’s accessible by weight, and in OBC’s case, it implies that 100 meters of filament will weigh 30% lower than 100 meters of PLA or PETG filaments. OBC has a density of 0.9 grams per cubic centimeter whereas PLA has a density of 1.2 grams per cubic centimeter. That implies that a 350 gram spool will print as many components as a 500 gram spool of PLA or PETG – regardless of their totally different weights, they each have round 320 meters of fabric on the spool. What this all means is that components 3D printed in OBC will float on water with out even making an attempt.

Versatile But Inflexible

OBC has a low flexural modulus which suggests OBC presents flexibility that different filaments simply cannot match. Its excessive fatigue resistance permits you to print issues like dwelling hinges that may be repeatedly exercised forwards and backwards with out fatigue. OBC’s mechanical properties may be tuned by particular design purposes – that’s: versatile when skinny however may be stiff when printing thicker cross sectional space components. In the long run, OBC’s uniqueness as a fabric is that practical components may be designed with sections which might be robust and inflexible, however have a flip closed lid that’s all a part of the identical 3D print.

OBC can be flexible or rigid depending on specific design considerations.

OBC may be versatile or inflexible relying on particular design issues.

Simple to Print

OBC is straightforward to print and requires little or no effective tuning along with your printer. It’s one of some versatile 3D printing supplies that’s approachable to inexperienced customers. The place different supplies can buckle within the printer’s extruder, as a filament this materials is inflexible sufficient to be simply extruded by principally any extruder kind. Although straightforward to print, it nonetheless boasts breakthrough options that solely Dow Chemical might design.

Printing OBC is simple; unlike other flexible 3D printing materials, it won't buckle in an unconstrained extruder.

Actual World Functions

The place a chemically resistant materials is required for a 3D print or a dwelling hinge that can be utilized again and again, OBC is the filament of selection. For instance, the same polyethylene may be present in merchandise like milk jugs and chopping boards, that are inflexible even at their thinnest level, and polypropylene, one other comparable materials, is utilized in contact instances and meals storage containers that are versatile and might snap shut again and again with out fatiguing. 

There are many real world applications of polypropylene and polyethylene, from food to chemical safety,

{Hardware} Issues

Printing temperatures for OBC are decrease than could be anticipated. Relying on the precise printer setup, splendid temperature is anyplace between 160°C and 200°C and 60°C and 100°C for the mattress. Which means that most printers on the market are able to printing this materials, with the temperature of the mattress being the limiting think about some instances; some printers can’t attain 100°C however can get shut sufficient to work. An necessary factor to notice is that OBC could be very particular with regards to mattress adhesion. The place different filaments work properly with quite a lot of adhesives, OBC will solely work with packaging tape, particularly polypropylene packaging tape. As soon as it’s utilized to the 3D printer’s mattress floor, prints will stick exceptionally properly.

Unlike other 3D printing materials, hardware considerations are pretty simple: a standard hotend and a very hot bed will work just fine.

Not like different 3D printing supplies, {hardware} issues are fairly easy: a regular hotend and a extremely popular mattress will work simply effective.

With its various set of properties, OBC is a magical filament with many alternative use-cases, and coming from Dow Chemical you possibly can belief they’ve completed their analysis into creating the best materials for 3D printing filament that’s straightforward to print and may be stiff or versatile primarily based on the design. OBC is out there in a number of colours in each 1.75mm and 3mm diameters so you may get printing instantly. To order your spool in the present day, take a look at the gathering: right here.

Comfortable printing!
