A quick Wiki search reveal the following companies as competitors:
Centerline[24]
HERMLE AG[2]
Impact Innovation GmbH[25]
Inovati[26]
Plasma Giken[27]
SPEE3D[28]
TITOMIC[29]
VRC Metal Systems[30]
GE (I added this)
Of these, some are more impressive than others. I must admit I like SPEE3D (Aussie private company), GE and Impact Innovation gmbh (Germany). Spee3d is a serious contender and is also based in Melbourne. A quick glance on their website they also work with the Australian Army and Navy; and has offices in Darwin, Michigan (USA), and are setting up offices in Lubeck (Germany), and NSW.
It also achieved many great milestones, including 3d printing of copper parts to kill Covid19. https://www.spee3d.com/?post_type=post

However, I believe Spee3d and TTT are ultimately targeting different sectors, with TTT patent in 3D titanium and special alloy printing for large industrial parts (with theoretically unlimited in size), where as Spee3d is targeting smaller parts and mostly made from copper but at "warping speed". You can't go with a promotional video like this! https://www.youtube.com/watch?v=y4vaxBrILFQ&feature=emb_logo

Finally, if this is the future of industry 4.0, I believe this space is too big for TTT to tackle alone. So I support both companies to transform our manufacturing capabilities and quietly hoping that they will merge in the future to form a giant.
