Dyndrite releases new advanced toolpath API to democratize previously impossible versions
The preselections for the 2021 3D Printing Industry Awards are open to vote, give your opinion now.
3D printing software developer Dyndrite has introduced a new and improved raster and vector toolpath API that enables the creation of transparent and shareable toolpath recipes.
Tool sets are now available under license to machine OEMs and end customers looking to develop and qualify new machines, materials and geometries, without requiring them to disclose their intellectual property (IP) or employ large software teams.
The Toolpathing API also allows these companies to develop print recipes for versions that were previously impossible or difficult to print.
âGenerating toolpaths or instructing a machine on exactly how to build your part is critical to the ultimate success of that part, especially as the types of parts, materials and capabilities of the part. machine evolve, âsaid Harshil Goel, CEO of Dyndrite. âMachine builders and their customers need more sophisticated tools to be able to consistently deliver quality parts, especially, for example, heat exchangers, turbines and other difficult-to-print geometries, to faster speed.
âThe innovations provided by Dyndrite far exceed the capabilities of the most advanced OEM software available today, and are just the beginning of a much-requested and long-awaited upheaval. “
Dyndrite AM Software Capabilities
Dyndrite was founded in 2016 and ran in stealth mode for three years while developing its fully native GPU geometry engine, the Dyndrite Accelerated Geometry Kernal (AGK). Soon after, the company launched its Additive Manufacturing (AMT) Toolkit at AMUG 2019, designed to facilitate a streamlined CAD-to-print workflow for industrial additive manufacturing.
By using AGK, Dyndrite’s AMT program is able to easily handle specific calculations such as arrays, media, and wafer generation, reducing time wasted redesigning parts.
Since then, Dyndrite has sought to accelerate the wider adoption of its software through its Developer Program, created to provide tools and resources to users of its AGK. The founding members of the development program included EOS and HP, and now include 3D Systems, SLM Solutions and ExOne.
In August last year, Dyndrite extended its strategic partnership with HP to license its AGK for use with the multinational printing company’s next-generation additive manufacturing portfolio. Months later, the two companies announced the development of HP’s Universal Build Manager (UBM), which is powered by Dyndrite and leverages the company’s GPU-accelerated geometry engine.
UBM is designed to help HP customers simplify, automate and accelerate construction readiness across their 3D printing workflows, while enabling mass customization of parts, automation of complex workflows and scalability.
More recently, Dyndrite released a new set of software APIs designed to make it easier for 3D printer manufacturers to implement advanced features like 3D printing without support. The toolsets were developed in partnership with the Company’s Developer Council and OEM customers, and are available as part of Dyndrite’s Accelerate Computation Engine (ACE) tool path API.
Dyndrite Raster and Vector Toolpath API
Dyndrite’s latest tool sets are available under license from manufacturers of 3D printers developing raster (DLP, LCD, binder jet) or vector (DMLS, SLM, SLS) processes, and who seek to accelerate development and the qualification of new machines, materials and geometries without having to reveal their IP.
For additive manufacturing to support mass production, Dyndrite says, the toolpath needs to be more sophisticated and automated. As such, the company’s new toolpath API offers capabilities that the 3D printing industry has long demanded and that other toolpath offerings fail to detect. An important feature of the API is its volumetric segmentation of 3D parts for the detection of upskins, downskins, inskins and other features.
This new capability would surpass existing layer-by-layer Boolean toolpath methodologies, which typically provide a â2.5Dâ preview of a part, by leveraging its GPU-based voxel engine to enable true 3D geometric queries. The True 3D Segmentation feature allows volumetric assignment of parameters for each segment of a part based on multiple variables, such as distance from faces up or down, while avoiding inefficient “2.5D” calculations .
Toolpath capability also generates “feature sensitive” machine tiles while using geometry to determine finely graduated process parameters and perform precise calculations. In addition, True 3D segmentation can create an unlimited number of thresholds to provide precise parameters for different construction conditions, and assign colors to distance thresholds to ensure that the correct parameters are deployed for difficult geometries like thin walls and overhangs.
âTrue volumetric analysis allows us to identify features that cannot be found using 2.5D analysis of layer data,â said Steve Walton, product manager at Dyndrite. âIt also allows us to develop more sophisticated toolpath strategies near fine features generated using any method: CAD geometry, mesh data from 3D scanning or implicit geometry.
âIt goes way beyond the Boolean layers used to determine upskin and downskin. We can now use 3D fields to assign parameters throughout the construction.
Dyndrite Toolpathing API Additional Features
In addition to volumetric segmentation of 3D parts, Dyndrite’s new toolpath API also allows offsets to be applied to contours and outer areas to improve part accuracy. The API also assigns geometric and tool parameters to each area, segment type, and layer in a part, and can programmatically apply tiling parameters regardless of the number of areas in place.
The API is further able to apply process mosaicism and micro-hatch geometry to prints, while merging, sorting and filtering previously created mosaics to determine tool usage and exposure based on filters. metadata, queries, sorting and machine constraints like gas flow.
âUsers don’t want black box solutions,â Goel said. âThe lack of transparency and democratization is holding back the additives industry, and Dyndrite’s goal is to make a difference by putting toolpath development and math within the reach of users. Users of additive manufacturing devices are often much more sophisticated than machine suppliers realize, and âsecretsâ prevent the adoption, success and qualification of new applications.
âThis knowledge should not be blocked by existing or newer machine suppliers. “
